What is a DNS SOA record?
The ‘start of authority’ record can store important info about the domain such as the email address of the administrator, when the domain was last updated, and how long the server should wait between refreshes.
Example of an SOA record:
| example.com | record type: | value: | TTL |
|---|---|---|---|
| @ | SOA | admin.example.com | 11200 |
The value here represents an email address ,which can be confusing because it’s missing the ‘@’ sign, but in an SOA record admin.example.com is the equivalent of admin@example.com.
