That's a nice place! Thanks Matthew.

I actually figured out I can run my own services for all my domains
on a dynamic IP without breaking any DNS related RFC.

I have 2 DNS servers, a master with static IP and a slave with dynamic 
IP (both can have a dynamic IP).
The resgistrar (godaddy) does not require IPs when defining custom DNS 
servers so one of the
DNS servers can run just fine on a dynamic IP as long as it's host has 
defined an A record and not a CNAME.
And as long as the Arecord for my domains is not set it should be fine.

But not having A records for the domains will of course mean that
I won't be able to access http://domain.tld , just http://www.domain.tld
But there is a solution to it too.
Having access to the master DNS I just can easly update all the A 
records with a script.
I use PowerDNS to host my domains and it's just a metter of running one
SQL query to have everything updated and working just fine.

All I have to do is to check if IP of my dyndns host has changed and run 
the SQL query
to update all the A records on the master server to match that new IP.


Thanks.

Marcin.
