I guess I didn't phrase my question well enough.  I'm looking for
software to *provide* dynamic service.  My understanding of how this
works is that a client program sends a sort of "authenticated ping"
periodically to the server, which checks the client IP address against
Apache's DNS records & makes changes if necessary.

I feel like this is probably more complex than it seems, though, and if
turnkey or (ideally) open-source scripts existed to set up a server in
this manner, I'd love to know about it.
