Can a top-level domain be all digits? If not, why not assume numeric if re.search(r".\d+$", addr) is not None?

I don't think anyone sane would create a top-level that's digits, particularly in the range of 0 to 255. That probably means that somebody is going to do it... ;-/

I think checking for 2 to 4 dotted octets in the range of 0 to 255 would be safest... Yes, you can probably get away with using the regex above, but I wouldn't want to.
