Hey Harry,

If I a not mistaken if you change your nameservers to FreeDNS you will
be able to have that dynamic IP Address that way. So your reverse lookup
should work just fine.

Only problem is that if your IP address changes, you would have a short
amount of time that your server would not respond (because of the IP
change). The default TTL on FreeDNS is 3600 seconds (1 hour).

Reading on the front page it says that you can edit the TTL if you add
your own domain. I don't know for sure how it all works because I have
never added on. It doesn't hurt to try and it seems like it would be a
lot better than what you are using now.

Hope this helps.
