The SOA record holds the DNS zone's general settings. You usually don't need to touch it: keep the default values if you're not sure what they do.
To edit it open Domains → domain name → Manage DNS and click the SOA row.
| Field | What it means |
|---|---|
| Primary server | our main DNS server: it is fixed |
| Responsible email | the address of whoever manages the zone |
| Refresh | how often, in seconds, secondary servers check the zone |
| Retry | after how many seconds they try again if the check fails |
| Expire | after how many seconds without an answer they stop using the zone |
| Default TTL | how long negative answers are remembered |
Click Save. If a value is out of range, the field tells you.
