You misunderstand how it's working.
The hesitation inherent in DNS lookups when telnetting to another system,
whether telnetting by IP or name, isn't on the local system. It's on the
remote system, to which you're telnetting.
The remote system is trying to lookup the name of the system from which
you're are telnetting.
There's a possibility that your problem could be related to the two NICs,
but I doubt it.
Try putting an entry on the server in the /etc/hosts file for your
computer's IP address, and then try telnetting in, again. It will
probably work much better.
