It works for me. One thought though: someday someone might want to get
around to allowing a DNS name in the host field, too. Can we define a
test that handles all three cases? Perhaps do this:

* If IP address contains only 0-9 and dot (easily coded with strspn()),
then it's old-style IP address; expect netmask as next field.

* If IP address contains only 0-9, dot, and slash, then it's CIDR;
there's no separate netmask field.

* Otherwise IP address is a DNS name; there's no separate netmask.
(This case can error out for now, unless you're feeling ambitious.)
