adding "fake" DNS server

[Andrew Kaplan]

One of my co-lo customers is concerned that MY nameserver appears when his
clients runs a 'whois'. I am trying to figure out a way to create a fake
second name server to appease his fears.

Could I add 'ns1.paranoidcustomer.com' to my DNS and point it to the same IP
address as my REAL name server. I would then register the new name server,
modify all the domains to the new nameserver.

Would this work,

TIA,
