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
