Aux root

Alt-rooted means that something other than the priced name system is in force see en:Alt root

As used here it means peering with the name servers here, which is automated like in letsencrypt as part of the SSO/user provisioning setup.

The easiest way to do this this is add the following servers, which are non-recursive, to the top of your resolver config such as resolv.conf:

• daclips.meansofproduction.biz
• malta.meansofproduction.biz

or their ip addresses if your resolver requires that.
