Configuring and Maintaining Your Server 59
4 Confirm removal and click OK.
Plesk updates automatically the zone name, hostname, administrator‘s e-mail address,
and serial number, and writes the default values for the rest of Start of Authority record
parameters to the zone files it maintains. If you are not satisfied with the default values,
you can change them through the control panel.
To change the Start of Authority (SOA) record settings in the server-wide DNS
template:
1 Click the Server shortcut in the navigation pane.
2 Click the DNS icon in the Services group.
3 Click SOA Preferences.
4 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.
Minimum. This is the time a secondary server should cache a negative response.
Plesk sets the default value of three hours.
5 Click OK. The new SOA record parameters will be set for the newly
created domains.
By default, transfer of DNS zones is allowed only for name servers designated by NS
records contained within each zone. If your domain name registrar requires that you
allow transfer for all zones you serve:
1 Click the Server shortcut in the navigation pane.
2 Click the DNS icon in the Services group.
3 Click the Common ACL icon in the Tools group. A screen will show all
hosts to which DNS zone transfers for all zones are allowed.
4 Click the Add New Address icon.
5 Specify the registrar's IP or network address and click OK.
