It's called a "dynamic DNS (DDNS) client" and runs on your router (it sends
the new IP to the DDNS server whenever your router gets one).

Most home routers come with built-in support for some DDNS protocols.
Of course, I recommend upgrading your router to a firmware like OpenWRT
if at all possible, and not just so you get a large choice of
DDNS clients.
