Abstract:
1. A method for resolving a domain name resolution request in a communications system including a data processing system, and a network, comprising: initializing a PPP (Point-To-Point Protocol) connection between the data processing system and the network for establishing a session; during said initialization intercepting an IPCP Internet Protocol Control Protocol message containing a DNS (Domain Name Service) server address by an interceptor program, the IPCP message communicated between the data processing system and the network; copying said DNS server address from said IPCP message, storing said copied DNS server address, and replacing said DNS server address in the IPCP message with an alternative address; resolving said domain name resolution request by intercepting said request by an alternate application; substantially simultaneously sending the request to each DNS server for which an address was stored; and receiving a resolved IP address by said data processing system.
