ABSTRACT:
A method and system for resolving domain name system (DNS) queries in a multiprotocol communications network is disclosed. The disclosed method includes in one embodiment receiving a destination address from a DNS server utilizing a first protocol; and communicating with a network element associated with the destination address utilizing a second protocol. In another embodiment, the disclosed method includes maintaining a profile for the DNS server and selecting the DNS server from a plurality of DNS servers utilizing the profile. In yet another embodiment, the disclosed method includes requesting a first address from the DNS server, where the first address is formatted according to a primary protocol, detecting a request failure in response to the request, and requesting a second address from the DNS server, where the second address is formatted according to a secondary protocol, in response to detecting the request failure.
