Custom hostname instead ISP's

Question

I have setup a Centos 5.5 server and a domain name (say mydomain.com) pointing to it (using bind9) with custom nameservers (like ns1.mydomain.com and ns2.mydomain.com). Everything works fine but there is something more I would like to have and don't know if it is possible.

Is it possible to have the returned host to be mydomain.com (PHP gethostbyaddr()), not host-static-x-y-a-b.myisp-provider.com? And how do I implement it if it's possible?

You need ownership to reverse that IP or IP block. Chances are if this is a home provider they will not allow that to happen.

If you are at a datacenter they might give you the rights or you will have to let them know what you want it reversed to and they will do it for you.

They will do it for you / Or you through an API unless you have one more more C networks (256 addresses these days, /24). Reverse mapping assignment in DNS always works in /24, so smaller networks can not be delegated. – TomTom Jan 04 '11 at 13:12
@TomTom http://tools.ietf.org/html/rfc2317 outlines a method for delegating blocks smaller than /24. – BillThor Jan 04 '11 at 17:23
