IB doesn't resolve it, it passes it to the network layer. Winsock 1 (which is on the Win95 workstations) treats an IP address as a string, so e.g. for a Win96 w/station presenting a server name of you get a long delay while it queries the network for a server with the *domain name* "" before, eventually, it will analyse the string and break it down to an IP address.

AFAIK, this doesn't happen with Winsock2...
