DNAME is a DNS RR Type that lets you basically CNAME? an entire domain. For instance with

test.meta.net.nz. IN DNAME wlug.org.nz.

looking up www.test.meta.net.nz gives www.wlug.org.nz. Support of this feature is somewhat fractured. DJB? refuses to implement it. Windows doesn't seem to even mention it1?, as far as I can tell only BIND support it.

However, since BIND supports it, when you query BIND for www.test.meta.net.nz it will also serve you a CNAME?, so most resolvers should be fine with dealing with this. Windows still seems to get confused however.

ie

test.meta.net.nz. 86400 IN DNAME wlug.org.nz. www.test.meta.net.nz. 0 IN CNAME www.wlug.org.nz. www.wlug.org.nz. 80464 IN CNAME hoiho.wlug.org.nz. hoiho.wlug.org.nz. 80464 IN A 203.97.10.50
