I have a root domain (say example.com) whose DNS is hosted on another provider. I want to delegate hosting of DNS of a subdomain (test.example.com) to opalstack's DNS servers so that I can create further subdomains off of that (e.g. www.test.example.com). I have set the name servers for test.example.com on the other provider to point to opalstack's name servers:
example.com. IN SOA ns.other-provider.com. user.other-provider.com. (...)
example.com. IN NS ns.other-provider.com.
example.com. IN NS ns2.other-provider.com.
test IN NS ns1.de.opalstack.com.
test IN NS ns2.de.opalstack.com.
test IN NS ns3.de.opalstack.com.
How do I configure DNS in opalstack so that its name servers appear as authoritative of test.examle.com (I cannot add NS or SOA records)
TIA,
Panayotis
