DNS Subdomains clarification and record structure.


I am trying to understand the difference / requirements in the DNS resource record types required for a sub domain.

So I understand for a normal zone we need a SOA, NS and the various A records etc.

However I am confused about how a sub domain is meant to look as far as the record structure goes.

Could I please get some clarification on this and a simple example to illustrate and compare it to a normal domain.

e.g acme.com and sub1.acme.com

Below is a subdomain example


If you want to delegate the server to another DNS Server you would create a NS (Name Sever) record in your zone file

subdomain             IN NS
subdomain             IN NS

or with no delegation

www.subdomain  IN A

or you could use a CNAME.

hope this helps
