Abstract: A method and apparatus for resolving where to forward DNS (domain name service) requests for a user simultaneously logged into more than one service existing on a data communications network utilizes an active service list (ASL) to keep track of the services that the user is currently logged into. The active service list includes a list of services sorted in a particular order based on information about the service and sometimes the order in which the user logged into the services. Each service has a profile that defines, among other things, the IP Address space for the service and a Domain attribute. To determine the appropriate service and, therefore, the appropriate DNS server for a DNS request, the QName from the DNS request is compared to the configured Domain attribute(s) for each service in the order of the ASL. If a match is found, then the DNS request packet is modified to re-direct the DNS request to the DNS server configured for the matched service.
