## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to the field of network communications, and more particularly to determining a network address of a computing device.
A computer network is a telecommunications network that allows computers to communicate and exchange data. In a computer network, networked computing devices pass data to each other through data connections. The data connections (e.g., network links) can be established utilizing cable media, and/or wireless media. A common example of a computer network is the Internet.
The Internet Protocol (IP) is a set of rules for sending information between computers on the Internet. Each computer that utilizes Internet Protocol has at least one IP address, which identifies the computer to other computers over the Internet. An IP address is a numerical label that is assigned to a computing device (e.g., a desktop computer, a laptop computer, a printer, etc.) that is communicating via a computer network, using Internet Protocol. IP addresses provide an identification of a host or network interface, and location addressing. IP addresses are binary numbers, but can be typically stored in text files and displayed in human-readable notation (e.g., 111.22.333.4). The Dynamic Host Configuration Protocol (DHCP) is a networking protocol used on Internet Protocol networks for dynamically distributing network configuration parameters, such as IP addresses for interfaces and services.
SUMMARY
Aspects of the present invention disclose a method, computer program product, and system for determining network information. The method includes in response to a computing device connecting to a computing system, the computing device identifying network information that corresponds to the computing system, wherein the computing system is configured to pass network information to the computing device while the computing system is powered on, but not logged in. The method further includes the computing device determining at least one network address for the computing system utilizing the identified network information that corresponds to the computing system. The method further includes the computing device displaying the determined at least one network address for the computing system.

DETAILED DESCRIPTION
Embodiments of the present invention allow for determining and displaying a network address for a client device. In one embodiment, a computing device establishes a connection to the client device and identifies network information corresponding to the client device. Utilizing the identified network information the computing device determines and displays one or more network addresses of the client device.
Some embodiments of the present invention recognize that computers belonging to an organization, and connected to the network of the organization often store confidential data. Only privileged users are able to access the sensitive data (e.g., via user ID and password authentication). A single user in the organization can own multiple computers, which can be located in different locations. To access a computer remotely, the user may need the corresponding Internet Protocol (IP) address of the computer. The IP address may be allocated to the computer using the Dynamic Host Configuration Protocol (DHCP).
The present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram illustrating data processing environment 100, in accordance with one embodiment of the present invention.
An embodiment of the data processing environment includes network 110, client device 120, and computing device 130. In one embodiment, client device 120 and computing device 130 communicate through network 110. Network 110 can be, for example, a local area network (LAN), a telecommunications network, a wide area network (WAN) such as the Internet, or any combination of the three, and include wired, wireless, or fiber optic connections. In general, network 110 can be any combination of connections and protocols that will support communications between client device 120 and computing device 130 in accordance with embodiments of the present invention.
In one embodiment, client device 120 is secure computer operating in a network of an organization (e.g., network 120). In various embodiments of the present invention, client device 120 may be a workstation, personal computer, personal digital assistant, mobile phone, or any other device capable of executing computer readable program instructions in accordance with embodiments of the present invention. In general, client device 120 is representative of any electronic device or combination of electronic devices capable of executing computer readable program instructions. Client device 120 may include components as depicted and described in further detail with respect to FIG. 3, in accordance with embodiments of the present invention.
Client device 120 includes user interface 122, operating system 124 and serial port 126. User interface 122 is a program that provides an interface between a user of client device 120 and a plurality of applications that reside the server computer (not shown). A user interface, such as user interface 122, refers to the information (such as graphic, text, and sound) that a program presents to a user and the control sequences the user employs to control the program. A variety of types of user interfaces exist. In one embodiment, user interface 122 is a graphical user interface. A graphical user interface (GUI) is a type of user interface that allows users to interact with electronic devices, such as a computer keyboard and mouse, through graphical icons and visual indicators, such as secondary notation, as opposed to text-based interfaces, typed command labels, or text navigation. In computing, GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces which require commands to be typed on the keyboard. The actions in GUIs are often performed through direct manipulation of the graphical elements.
Operating system 124 collection of software that manages computer hardware resources of client device 120 and provides common services for computer applications. Operating system 124 is a component of the system software of client device 120. Serial port 126 is a physical communication interface that client device 120 utilizes to transfer data. In example embodiments, serial port 126 can be a Universal Serial Bus (USB) port, an Ethernet port, or other ports that are capable of utilizing serial communication.
Computing device 130 includes display 132 and network address program 200. In one embodiment, computing device 130 is a USB storage drive that is capable of communicating with client device 120 via network 110 or serial port 126. In embodiments where computing device 130 is a USB storage device, computing device 130 may include components as depicted and described in further detail with respect to persistent storage 308 in FIG. 3 (e.g., a removable storage device), in accordance with embodiments of the present invention. In another embodiment, computing device 130 is a mobile computer or mobile phone capable of communicating with client device 120 via network 110 or serial port 126. In embodiments where computing device 130 is a mobile computer or mobile phone, computing device 130 may include components as depicted and described in further detail with respect to FIG. 3, in accordance with embodiments of the present invention. In various embodiments, computing device 130 can be any other device capable of communicating with client device 120 (e.g., via network 110 and serial bus 126), and executing computer readable program instructions in accordance with embodiments of the present invention. Display 132 provides a mechanism to display data to a user of computing device 130, and may be, for example, a liquid-crystal display (LCD) screen. Display 132 can also function as a touch screen, such as a display of a tablet computer. Network address program 200 determines and displays a network address of a computer (e.g., client device 120), in accordance with embodiments of the present invention.
In various embodiments, computing device 130 can connect to client device 120 (e.g., via serial port 126) and communicate with operating system 124. In one embodiment, client device 120 runs an authentication program (not shown) that allows computing device 130 to communicate with operating system 124 without client device 120 being logged in. In another embodiment, client device 120 is configured to pass network information to computing device 130 while client device 120 is powered on, but not logged in. For example, client device 120 assigns computing device 130 to have administrator privileges relative to operating system 124. In an example embodiment, network address program 200 operates on computing device 130, which has administrator privileges on operating system 124 of client device 120, and is capable of communicating with operating system 124 without write access to client device 120. In one embodiment, client device 120 is logged in when client device 120 receives and authenticates (e.g., via user input into user interface 122) a set of authentication credentials that correspond an approval to access client device 120 and information stored on client device 120. In another embodiment, client device 120 is powered on, but not logged in when client device 120 is powered on and operating (e.g., in a boot-up phase), but has not received and/or authenticated a set of authentication credentials. For example, if client device 120 is displaying a log in prompt to access operating system 124, then client device 120 is powered on, but not logged in. In another example, if client device 120 is booting up and has not yet displayed a login prompt, and the login prompt is required, then then client device 120 is powered on, but not logged in.
FIG. 2 is a flowchart depicting operational steps of network address program 200, a program for determining and displaying a network address of a client device, in accordance with an embodiment of the present invention. In one embodiment, network address program 200 initiates in response to computing device 130 connecting to client device 120 (i.e., network address program 200 is an auto-run utility on computing device 130). In another embodiment, network address program 200 operates on computing device 130, which has administrator privileges on operating system 124 of client device 120.
In step 202, network address program 200 establishes a connection to the client device. In one embodiment, computing device 130 connects to client device 120, and network address program 200 establishes a connection to operating system 124 of client device 120. In another embodiment, client device 120 is powered on, but not logged in (e.g., not logged into a user profile of operating system 124). For example, computing device 130 establishes a connection to client device 120 while client device 120 is displaying a log in prompt to access operating system 124 (i.e., client device 120 is powered on, but not logged in). In another example, computing device 130 establishes a connection to client device 120 while client device 120 is booting up and has not yet displayed a login prompt, and the login prompt is required. In many embodiments, to be logged into client device 120, a user or a program enters authentication information (e.g., passwords or other forms of identification), into a field of a login prompt of client device 120. In response to receiving this authentication information, client device 120 confirms whether the authentication information is valid. If the verification information is valid, then client device 120 allows the user or program access to and use of operating system 124. In some embodiments, the access to and use of operating system 124 for a given user or program is governed by a profile, such as a user profile. Such a profile provides the limits of privileges that are applied to a user or program that has been granted access to and use of operating system 124. For example, some privileges allow the use of certain functions of operating system 124, while other privileges dictate a format and display of a graphical user interface used by operating system 124. In an example embodiment, computing device 130 is a USB storage device that connects to client device 120 via serial port 126. In another example embodiment, computing device 130 is a mobile phone that connects to client device 120 via serial port 126 or network 110 (e.g., wireless network communications).
In step 204, network address program 200 identifies network information corresponding to the client device. In one embodiment, network address program 200 accesses and utilizes Basic Input/Output System (BIOS) routines (e.g., system calls) of client device 120 to identify network information from a network adaptor (not shown) of client device 120. In another embodiment, network address program 200 communicates with operating system 124 identifies information corresponding to network communications of client device 120. For example, network address program 200 identifies network information that includes an IP address associated with client device 120, a media access control (MAC) address associated with client device 120, or other information associated with network communications of client device 120. In one embodiment, network address program 200 is capable of communicating with operating system 124 through native commands associated with operating system 124. In an example embodiment, network address program 200, via operating system 124, queries a router (not shown) associated with client device 120, and receives network information that corresponds to client device 120. In this embodiment, a router associated with client device 120 is capable of providing network information that includes an IP address that is assigned to client device 120 (e.g., via Dynamic Host Configuration Protocol (DHCP)).
In step 206, network address program 200 parses the identified network information. In one embodiment, network address program 200 parses the identified network information corresponding to client device 120 (identified in step 204) to identify data that is associated with network addresses (e.g., an IP address, a MAC address, etc.) of client device 120. In an example embodiment, network address program 200 utilizes metadata included in the identified network information, which can provide an indication of network addresses of client device 120. In another example embodiment, network address program 200 parses the identified network information by isolating one or more sections of the identified network information that corresponds to network addresses of client device 120.
In step 208, network address program 200 determines one or more network addresses for the client device. In one embodiment, network address program 200 utilizes the parsed identified network information corresponding to client device 120 (from step 206) to identify one or more network addresses that correspond to client device 120. In an example embodiment, network address program 200 determines one or more IP addresses associated with client device 120. In this embodiment, network address program 200 can identify the one or more IP addresses associated with a network adaptor of client device 120 (e.g., identified utilizing BIOS of client device 120), and one or more IP addresses that a router has assigned to client device 120 (e.g., via DHCP). In another example embodiment, network address program 200 determines one or more MAC addresses associated with client device 120. In other embodiments, network address program 200 can determine any type of network address, or a combination of types of network addresses that are associated with client device 120. In another embodiment, network address program 200 stores the determined network addresses on computing device 130.
In step 210, network address program 200 displays the determined one or more network addresses. In one embodiment, network address program 200 displays the determined one or more network addresses for client device 120 (from step 208) on display 132 of computing device 130. In another embodiment, if network address program 200 determines more than one network address for client device 120 (in step 208), then network address program 200 sequentially displays the determined network addresses. For example, network address program 200 displays “IP Address=111.22.333.4” followed by “MAC Address=01-23-45-67-89-ab.” In other embodiments, network address program 200 can display the determined network addresses on a display other than display 132 on computing device 130 (e.g., a display not shown).
In another embodiment, network address program 200, via computing device 130, is capable of communicating with additional client devices (not shown) via network 110. In an example, in response to determining the IP address of client device 120, network address program 200 can provide the determined IP address to a user (on a client device not shown) via network 110.
