Custom DNS resolvers
Configure DNS server addresses for DNS monitor checks.
DNS monitors can run their lookups through specific DNS servers. Enter up to five unique IPv4 or IPv6 resolver addresses, comma-separated, in the DNS resolvers field of a DNS monitor. Leave the field empty to use the worker's operating-system resolver behavior. Hostnames and malformed addresses are rejected.
Resolver configuration is part of the monitor's saved configuration, so it survives edits, cloning, export/import, templates, bulk creation, and editor recipes.
