2 Click the domain name you need.
3 Click the DNS icon.
4 Click SOA Preferences.
5 Specify the desired values:
TTL. This is the amount of time that other DNS servers should store the record in
a cache. Plesk sets the default value of one day.
Refresh. This is how often the secondary name servers check with the primary
name server to see if any changes have been made to the domain's zone file.
Plesk sets the default value of three hours.
Retry. This is the time a secondary server waits before retrying a failed zone
transfer. This time is typically less than the refresh interval. Plesk sets the
default value of one hour.
Expire. This is the time before a secondary server stops responding to queries,
after a lapsed refresh interval where the zone was not refreshed or updated.
Plesk sets the default value of one week.
