I think the best solution for you would be some form of VPN,
perhaps IPsec, or vtund (if you're using *nix).

Generally, when you change your IP, you will lose the connection.
And you also have to tell that machine that you changed the IP,
either manually (ssh to server, as you wrote) or automagically
(using the script which will ssh, change the file, signal the DB).

If you set a VPN, you will always have the same IP address, say
192.168.111.111, no matter what your ISP has selected for you now,
and connections to that address can persist your IP changes
(depends how VPN is set up, but it's doable).
