Reverse IP lookup resolves to old domain

Question

A site I administer recently rebranded under a new domain name. I updated the DNS to forward the old to the new, but reverse IP lookups are still resolving to the old domain. I don't see anywhere in my DNS settings where this could be a problem. Will this take longer than a regular DNS update or is there something else I can do to fix this?

Thanks!

The reverse DNS isn't usually set on your server but by the host datacentre that manages your server. When I setup a new server I usually send a message to the support saying, "Please set reverse DNS for host.example.com to 123.123.123.123 and please remove reverse DNS for old.example.com."
