That's actually what the excerpt above says will happen.

gethostname returns "b.com", removing everything up to the first period
yields ".com", and that removed from "a.b.com" gives you "a.b".

I don't care if it needs to be changed, but that does exactly what it
says on the tin so far as I can see.
