Yeah, it's a good idea. Gnus should kill off all network connections
when the IP address changes.
It's not a 100% solution (you may be tethered behind a device that
changes address, and they you won't discover the situation because your
own IP address doesn't change), but it's better than nothing.
However, I wonder whether this could be done more generally? That is,
allow functions to "register" actions to be done when the IP address
changes, so that we don't have to duplicate this code in several
packages...
