I'm interested in a special use-case, where (say, in an emergency), access to most of the Internet (and hence the root servers) is cut off. In this situation, there is an emergency connected network consisting of several domains, each with known nameserver IP addresses. The hosts in domain aaa.com know (typically, via DHCP) about the nameservers for their domain, but nothing about domain bbb.com.

At first I thought that one should place "glue" NS records for domain bbb.com in the zone for aaa.com, so that hosts in aaa.com that use the aaa.com nameservers, will be able to refer to the hostnames in domain bbb.com.

I understand that one can do this for subdomains. However, a bit of research seems to suggest that a stub zone is the proper way to do this. Is this what a "stub" zone is for?
