Traceroute an IP and the last entry gives me the host the IP resolved to. How do I change that?

Is it LAN or WAN IP? Do you have control of? – quanta Aug 13 '12 at 03:59 — quanta, Aug 13 '12 at 03:59
Simple, just traceroute a different IP address. – John Gardeniers Aug 13 '12 at 05:20 — John Gardeniers, Aug 13 '12 at 05:20

You need to change the PTR record for that IP. If this is an RFC1918 IP block or is a net block allocated or SWIPed to you, then you can do this yourself. If not, then you'll need to contact your ISP or whomever owns that netblock.

I just learned this after posting the question. I have some servers with SoftLayer.com and I see they have an option to update my RDNS. I looked it up and that's exactly it! Thanks again! – Aco Strkalj Aug 13 '12 at 04:02

You change the result of the reverse lookup by changing the PTR record in the reverse lookup zone - the owner of the IP range controls where that record's delegated to.

If you have access to the in-addr.arpa zone for that IP range, then change it there. If you don't, ask your ISP.
