If that is a frequent need, it would be reasonable to add an API
address = ipaddr.IP(input, allow_mask=False)
which would raise an exception if a mask was specified (as an
old-style bit mask, or in CIDR form).

With the current API, you don't need to write it in such a quirky
way. Instead
if address.numhosts != 1:
raise TypeError("Expecting IP address, not network")
would do as well.

Well, you deliberately make it appear more quirky than it actually is.
