This is a poor way to do dynamic DNS.

I think you're probably trying to solve the wrong problem here, but you
can add a "command=/usr/bin/dowhatever" directive to the line for your
key in authorized_keys, and when that key is used to log in, that's the
command that gets run. This will reduce your risk somewhat.
