That sounds like a job for a dynamic dns client.

existing Debian packages:

ddclient (multiple backend services supported)
ddupdate (also supports multiple services, more plugin-oriented)
dyfi  (Finnish users only)
dyndns   (multiple services)
ez-ipupdate (multiple services)
ipcheck (dyndns protocol specific, but many services use it)
isc-dhcp-client-ddns  (adds dynamic dns to DHCP)

Don't reinvent the wheel, when it looks like it already has
seven versions already.
