  Okay, I don't know why virSocketAddrIsNetmask() code didn't work
for you, I'm sure I had tested it even on weird examples, but the
replacement looks fine to me.

  A following cleanup to this cleanup might be to remove all nwIPAddress
and just use virSocketAddr, I guess this would make the code simpler
too.

  Thanks for the cleanup, looks fine to me,
