Of course, any forwarding adds a additional hop and therefore additional delay
and an additional possible point of failure.
But this is true for any net

No, you would never get rid of a valid delegation of a child zone; why *reduce*
the resolvability of that zone? Whatever you do to get around this connectivity
issue would be *in*addition*to* the delegation, not as a
connectivity. But now we’re talking about multi-hop
recursive resolution, and that’s definitely sub-optimal.

This is strictly internal. There are no external clients or servers
involved. All three of the servers have recursion turned ON.
Server A has a domain (example.com.)

I have a child domain that is delegated to a second site. Pretty
straightforward situation. In the parent zone I have NS records that point
to the DNS servers at the second site.
The issue comes up when a slaved copy of the parent domain is running at a
third site and that third site doesn't have
16 matches
