An SOA(State of Authority) Record is an essential part of a Zone file. The SOA record is a way for the Domain Administrator to give out simple information about the domain like, how often it is updated, when it was last updated when to check back for more info, what is the admins email address and so on. A Zone file can contain only one SOA Record.
Here is an example of the content of an SOA record:
|ns1.dnsimple.com admin.dnsimple.com 2013022001 86400 7200 604800 300|
The SOA record includes the following details:
- The primary name server for the domain, which is ns1.dnsimple.com or the first name server in the vanity name server list for vanity name servers.
- The responsible party for the domain, which is admin.dnsimple.com.
- A timestamp that changes whenever you update your domain.
- The number of seconds before the zone should be refreshed.
- The number of seconds before a failed refresh should be retried.
- The upper limit in seconds before a zone is considered no longer authoritative.
- The negative result TTL (for example, how long a resolver should consider a negative result for a subdomain to be valid before retrying).
