We had a single reverse lookup zone in our 2008 DNS with the name:
220.10.in-addr.arpa (I'll call this the mother zone) which was hosting records from 3 different subzones / child zones:
10.220.0.x, 10.220.1.x and
In trying to separate records of one zone from the others, I created initially two zones,
1.220.10.in-addr.arpa that are replicating to all DNS servers in the domain. At first, these zones appeared at the same level as the
220.10.in-addr.arpa but then after a while two grayed out containers corresponding to each child zone showed up underneath the mother zone in addition to the individual ones I created.
Why are these containers grayed out and why did they not show up at the beginning? Does grayed out mean that they are delegated?
