uuid._ipconfig_getnode did not validate the maximum length of the value,
so long as the value had the same type of formatting as a MAC address.
This let it select DUIDs as MAC addresses. It now requires an exact
length match.

^ at the begin of the pattern is not needed since re.match() always matches at the start of the string.

You can use re.fullmatch() in Python 3.

Not a problem. Would it be better to use re.fullmatch() or stick with $ to ease backport to 2.7?

I think it is better to use re.fullmatch() in Python 3 and $ in the 2.7 backport.

I've made the requested changes (I think). I'm happy to do the work for the backporting, but my understanding is that those PRs would happen after this PR is merged?
