Information: - In telecommunications networking, a residential gateway (home gateway) allows the connection of a local area network (LAN) to a wide area network (WAN). The WAN can be a larger computer network (such as a municipal WAN that provides connectivity to the residences within the municipality), or the Internet. WAN connectivity may be provided through DSL, cable modem, a broadband mobile phone network, or other connections. - The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. - dhcpd ( an abbreviation for '' DHCP daemon '' ) is the name of a program that operates as a daemon on a server to provide Dynamic Host Configuration Protocol ( DHCP ) service to a network Clients may solicit an IP address ( IP ) from a DHCP server when they need one . The DHCP server then offers the '' lease '' of an IP address to the client , which the client is free to request or ignore . If the client requests it and the server acknowledges it , then the client is permitted to use that IP address for the '' lease time '' specified by the server . At some point before the lease expires , the client must re-request the same IP address if it wishes to continue to use it . Issued IP addresses are tracked by dhcpd through a record in the dhcpd.leases file . This allows the server to maintain state over restarts of the dhcp service , which could otherwise lead to duplicate IP addresses being issued when server issued the same IP address again while another client still has the right to use it . This reference implementation of DHCP is developed by the Internet Systems Consortium and is supported on Linux , Mac OS X , FreeBSD , Solaris , AIX and HP - UX . Remote access to a running instance of dhcpd is provided by the Object Management Application Programming Interface ( OMAPI ) . On the server side , this interface allows for editing of registration information for managed nodes . Uses on the client include fetching configuration information , releasing and renewing leases , and changing which interfaces are managed by the DHCP client . - A network administrator maintains computer infrastructures with emphasis on networking. Responsibilities may vary between organizations, but on-site servers, software-network interactions as well as network integrity/resilience are the key areas of focus. - The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks. The DHCP is controlled by a DHCP server that dynamically distributes network configuration parameters, such as IP addresses, for interfaces and services. A router or a residential gateway can be enabled to act as a DHCP server. A DHCP server enables computers to request IP addresses and networking parameters automatically, reducing the need for a network administrator or a user to configure these settings manually. In the absence of a DHCP server, each computer or other device (e.g., a printer) on the network needs to be statically (i.e., manually) assigned to an IP address. - An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there." What object entity has the relation of 'instance of' with the subject 'dhcpd'? Choices: - administrator - area - communication - computer network - emphasis - home - internet - internet protocol - ip address - key - label - municipality - name - network - principal - protocol - route - router - software - suite - wide area network
