[dns-operations] How Recursive Resolvers handle domains re-delegated at the same level

[Stephen Malone]

Hi Folks,

I’m looking to understand how recursive resolvers handle DNS domain re-delegations at the same level. For example:

=Parent zone: contoso.com=
@                            IN           SOA       ns1.contoso.com. hostmaster.contoso.com. (…
Subzone              IN           NS          ns1.IntermediateNS.com.

=Intermediate zone: Subzone.constoso.com; Name Server: ns1.IntermediateNS.com.=
@                            IN           SOA       ns1.IntermediateNS.com. hostmaster.contoso.com. (…
@                            IN           NS          ns1.RedelegatedNS.com.

=Re-delegated zone: Subzone.constoso.com; Name Server: ns1.RedelegatedNS.com.=
@                            IN           SOA       ns1.RedelegatedNS.com. hostmaster.contoso.com. (…
@                            IN           NS          ns1.RedelegatedNS.com.

Will any recursive resolvers products/versions break with the above configuration?

Thanks,
