This is was for *supporting* RENUMBERING not RENAMING. The whole section should just be excised from this RFC. It is just wrong to say you can't use DNAME in a part of the tree. It also gives the wrong impression that DNAME is deprecated when it is most definitely not. As part of the working group at the time this went through I apologise for dropping the ball by letting this section stay. If you talk to others in the WG you will find similar opinions. >It will indeed work, but not work everywhere. Redhat boxes for >instance apparently croak on it.

Broken resolvers need to be fixed. >I guess DNAME is getting used more for a purpose for which it >wasn't intended at first ;) No. RENAMING was a explicitly intended use. Mark
