Abstract

The present invention is directed at a method and apparatus of resolving an address location for a web site when connected with a virtual private network (VPN). Once the public host is connected to, or logged on to, the VPN, a software module within the public host monitors domain name requests and routes them to a domain name server (DNS) associated with the VPN. The VPN DNS then resolves the address Location request and returns the address location to the software module in the form of a domain name response. The software module then forwards the address location to the requesting public host.

Claims

1. A method for resolving a web site address when connected with a virtual private network (VPN) comprising the steps of:

receiving a domain name request from a public host;

resolving said domain name request at a domain name server (DNS) associated with said VPN; and

returning an address location corresponding to said domain name request to said public host.
