need advice on nameserver configuration

on a Red Hat server I am running name server (ns1.mynameserver.com , ns2.mynameserver.com) can anybody advice how to set my server so that it automatically forwards domains that have ns1.mynameserver.com , ns2.mynameserver.com as nameserver address to a specific url/page, without actually adding hosting or dns records for domains on a server manualy
for example: I have somedomain.com once I change its nameserver from domain's registrars(enom godday...) control panel to ns1.mynameserver.com , ns2.mynameserver.com domain automatically will get forwarded to some page/url
thanks
