The easiest solution then is just to configure your nameserver to be a
master for the ourdomain.com domain, and include machine.ourdomain.com
as an A record in the zone in addition to all the entries you have on
the "official" nameservers. Your LAN clients will get back answers from
your nameserver (which knows about machine.ourdomain.com) and the rest
of the Internet will get back answers from the official nameservers
(which won't recognise machine.ourdomain.com). Just be sure to keep your
private version of the zone in sync with the official one when you make
changes.
