HOWTO Disable Named

If you already have an authoritative DNS server on your network, make sure your DNS server list in hieradata/simp_def.yaml doesn’t include your machine’s local IP address. SIMP should automatically turn off the named service.

However, if you are running an alternative DNS provider on SIMP and need to keep your IP address in resolve.conf, set simplib::resolv::named_autoconf: false in Hiera.
