We have an internal root hint server and several nameservers for different domains. Let's say we have 3 domains with different nameservers example.com, solo.example.com, dmz.example.com. So each of the domains have 2 NS records.

My question. Is there a way for me to hint towards dmz.example.com and solo.example.com while still hinting towards example.com? So that if example.com is not reachable then dmz.example.com and solo.example.com could still be reachable.

Example of what the root hints file COULD look like.

.      6000              IN    SOA   root.example.com. admin.example.com. (
                               2023071420
                               1D
                               1H
                               1W
                               1D)
                         IN    NS    root.example.com
root.example.com.        IN    A    172.16.1.10

example.com.             IN    NS   ns1.example.com.
example.com.             IN    NS   ns2.example.com.
ns1.example.com.         IN    A    172.16.10.1
ns2.example.com.         IN    A    172.16.10.2

solo.example.com.        IN    NS   ns1.solo.example.com.
solo.example.com.        IN    NS   ns2.solo.example.com.
ns1.solo.example.com.    IN    A    172.16.15.1
ns2.solo.example.com.    IN    A    172.16.15.2

dmz.example.com.        IN    NS   ns1.dmz.example.com.
dmz.example.com.        IN    NS   ns2.dmz.example.com.
ns1.dmz.example.com.    IN    A    172.16.17.1
ns2.dmz.example.com.    IN    A    172.16.17.2

As it turns out there is no solution for this. DNS simply doesn't work this way.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
