We run DNS servers for a domain like child.parent.edu. The parent.edu domain has an NS record for the child and everything is working. An administrative error on the child domain turned off zone transfers to the parent. After some time users pointing to the parent domain or other outside domains could not resolve host names at child.domain.edu.
My question, is there a way to configure the parent domain's NS record for child.parent.edu so that the child domain does not need to do zone transfers to the parent?
When the child stopped doing zone transfers to the parent a nslookup using parent.edu's DNS server would only return the host names of child.parent.edu's DNS server with no IP addresses. Consequently DNS request to the parent were not forwarded to the child and generated errors on the parent. When the zone transfers were restarted everything went back to working.
