My suggestion would be to put a domain name there in the domain that hosts the domain, a hostname that can receive the traffic generated by any tool that uses the mname in the SOA for something.
In the interest of sanity, I'd suggest adding "should answer queries about said domain with the AA bit set" (in addition to swallowing/properly rejecting/processing updates and allowing/properly refusing zone transfers). That is the The Right Thing to do, IMHO, but it might be hard to get that kind of enforcement into any kind of document short of an ops memo inside one organisation. I for one require it for anything I operate. -- Måns Nilsson Systems Specialist +46 70 681 7204 cell KTHNOC +46 8 790 6518 office MN1334-RIPE
