SOA Record
Stands for Start of Authority
The SoA record indicates that "this nameserver is the best source of information for the data within this zone".
- therefore, the nameserver that this record exists on is authoritative because of the SoA.
There can only be one SoA per zone.
This is the most important address record, and must be specified.
- Contains the authoritative master nameserver for the zone or domain, as well as an admin email that we specify.
- Also contains administrative information about the zone
- MNAME - the primary nameserver for the zone
