SOA Configuration Form

The SOA settings for a zone are as follows:

• Name Server (Listed only for zone-specific SOA). The name of the server on which the zone resides.
• Administrator Email. The email address of the administrator responsible for the master DNS name server.
• Refresh interval. The frequency (how often), in seconds, the slave name server checks with the master name server for updated lookup information.
• Retry interval. The frequency (how long), in seconds, a slave server must wait before retrying a failed zone transfer from the master name server. Normally, the retry interval is shorter than the refresh interval.
• Expire interval. The upper limit, in seconds, that a slave name server can use the lookup data it currently has before the data expires.
• Minimum Time To Live. The length of time, in seconds, the slave name server can cache data.
