- Plesk for Linux
- Plesk server is acting as hidden DNS master server: external NS servers are specified in Tools & Settings > DNS Settings (or DNS Template) and all zones created in Plesk are propagated to these servers. They are serving all DNS requests for domains hosted on the Plesk server.
- One of this external NS servers is added to a SOA record as a primary master nameserver.
- Changes in DNS zones (or notifies) are not sent to the NS server specified in an SOA record.
This is the expected behavior of the BIND DNS server. The following can be found in the BIND 9 Administrator Reference Manual:
PLESK_INFO: Normally a NOTIFY message is not sent to the SOA MNAME (SOA ORIGIN) as it is supposed to contain the name of the ultimate master.
On Plesk servers using BIND as the DNS server, the “notify-to-soa” option is in effect since Plesk 18.0.42.
As a workaround, the following actions can be performed:
Add the line
notify-to-soa yes;to the field Additional DNS settings in the menu Tools & Settings > DNS Settings > Server-wide Settings and click OK or Apply to apply the changes.
