1. A method of deciding in which context a domain name system name should be resolved comprising:
- querying a domain name system resolver with a host name to resolve;
querying a context library for context information;
receiving the context information from the context library in response to the context query;
querying a domain name system for the IP address corresponding to the host name; and
receiving from the domain name system the IP address for the context information supplied for the queried host name in response to the domain name query.

Abstract
A system and method for deciding in which context a DNS name should be resolved. A SIP server implements presence functionality for use in context discovery of a DNS name. When the terminal is aware of the context to which the DNS name is related, the terminal may perform a correct DNS lookup for the specific DNS name and context. The DNS resolve library may be modified with the context for the DNS name.

8. A system for deciding in which context a DNS name should be resolved, comprising:
-
a terminal located within a domain and including a DNS resolve library;
a SIP presence server operatively connectible with the DNS resolve library, the SIP presence server including a profile; and
DNS infrastructure in communication with the DNS resolve library;
wherein the SIP presence server provides context for modification of the DNS resolve library for resolution of the DNS name via the DNS infrastructure using the provided context. - View Dependent Claims (9, 10, 11)
