The SOA (start of authority) record is the most crucial record in a DNS entry. It conveys more information than all the other records combined. This record is called the start of authority because it denotes the DNS entry as the official source of information for its domain.
The SOA record is one of the most complex entries available. It specifies a lot about a domain: the name of the master nameserver ('the primary'), the hostmaster and a set of numbers indicating how the data in this domain expires and how often it needs to be checked.
Every zone file must contain a SOA record.
Together with DNS templates that define the default structure of the rest of resource records, the ability of SOA record templates creation and specifying a particular TLD a SOA template is to be applied allows you to explicitly specify the structure of domain zone files created automatically.
One of the SOA record templates can be specified as a default one. This record is to be applied to all TLDs that do not have a specific SOA record template assigned.
To add a default SOA template, enter no TLDs into a SOA configuration form.
You can create one SOA record template per one TLD.
Each SOA template has an owner account (i.e., a vendor) specified. By default, the owner is Provider account if a SOA template is added from Provider Control Center, or Reseller account, if a SOA template is added from Reseller Control Center. The Owner field in a SOA record configuration form is read-only.
