Delegate sub-domain to another name server in bind…
Consider the following:
- You own/control your name server for your zone company.com
- You have a sub-domain you want to create as a separate zone and delegate/assign the responsibility of that sub-domain to another name server. In this case, let’s say geo.company.com is the sub-domain. The idea is that you want to create DNS records for the sub-domain (say ops1.geo.company.com) and manage those DNS records through a different DNS name server.
- You are running your zone company.com on a bind server running on Linux
It’s actually very simple, you add the following entries to your zone file for company.com:
; Delegating the geo.company.com subdomain to another NS – being gtm.company.com
geo IN NS gtm.company.com.
gtm IN A 10.10.1.20 ; this is the glue record
Don’t forget to reset named (rndc reload). You will get a warning unless you add a second NS record. So you should have:
; Delegating the geo.company.com subdomain to another NS – being gtm.company.com
geo IN NS gtm1.company.com.
geo IN NS gtm2.company.com.
gtm1 IN A 10.10.1.20 ; this is the glue record
gtm2 IN A 10.10.1.21 ; this is the glue record
