Abstract:
1. A method of redirecting a Domain Name Server (DNS) request packet generated by an application, the method comprising: reading an Internet Protocol (IP) address of an infrastructure-based Domain Name Server that is initially stored in the operating system of a client node at start up; replacing the IP address of the infrastructure-based Domain Name Server with an IP address of the client node such that the operating system interprets the infrastructure-based Domain Name Server as being located at the IP address of the client node; running a second application at a Transport Layer Protocol (TLP) port which listens for packets addressed to the Transport Layer Protocol (TLP) port designated for Domain Name System Servers; generating, at the application in the client node, the DNS request packet based on a requested domain name; redirecting the DNS request packet to the IP address of the client node; determining, by the second application, whether to forward the DNS request packet either to the infrastructure-based Domain Name Server or at least one other node in an autonomous ad hoc network based at least in part on a network identifier associated with the requested domain name; and forwarding the DNS request packet to either the infrastructure-based Domain Name Server or the autonomous ad hoc network.
