I want to create a separate zone file for sub.example.com so that I can more easily manage host records such as host1.sub.example.com, host2.sub.example.com, etc., rather than having hosts in my parent zone such as host1.sub, host2.sub, etc.

I do not want to delegate the subzone to different nameservers, I just want to keep it on Linode with my parent zone. How do I achive this? Do I setup five nameserver records for sub.example.com and point them to ns1.linode.com, ns2, ns3, ns4 and ns5?

Do I need these "glue" A records I've been reading about?

If someone can clear this up for me, I'd appreciate it, thank you.

No one?

So, I went ahead and created another zone for the domain sub.example.com, set the A records and a host (test1.sub.example.com) and everything seems to be working. Then I tried going to my parent zone and created an A record for host (test1.sub) to see if it would override or something (it shouldn't), and it didn't. I assume this is all because I didn't delegate to different name servers?

Anyway, I think this is working and I didn't have to mess around with any NS records. If I did something wrong, someone please tell me. Otherwise, I guess I'm good to go.

This is basically what I did.
