Click + ACMEv2 DNS-01 Nameservers to enter the list of DNS nameservers for DNS-01 validation for ACMEv2. Use the following syntax for each entry.

<ip>:<port>

Where:

  • <ip> is the IPv4 address of the DNS nameserver.
  • <port> is the port (typically port 53) of the DNS nameserver.

For example:

192.0.2.0:53

Mandatory: No. If this setting is absent, the ACMEv2 service will use the nameservers in the resolv.conf file.
