Currently speaking we can in theory re-enter the same records multiple times.

Example

We query the A record for domainX.org
We get back a CNAME instead and store it as a CNAME

Later we query for the same domain's CNAME and of course we will get the same CNAME results and thus have two of the same record

Also this duplication check will come in handy once we start to query for the A/AAAA records of Mail servers and/or Nameservers

To reduce the amount of DNS queries we need to make, should implement a check that if no NZ records are found then skip the rest of the DNS RR types. Since if there are no NS records there 100% sure no other records either
