Liam,
Not altogether happy with the suggestion below. It works - for now.
A more generic solution might be to replace the hard-coded "9" with a call
to strrchr() on the last 'dot' character position (minus one). Then it
should work on any properly formed IP address.
Thereafter parameterise the subnet address portion and things become
mobile/re-usable.
Regards,
