Recursive DNS edit

The DNS recursor is ha-bind-recursor.esi.toolserver.org, which runs on the HA cluster in the bind-recursor resource group. This handles recursive queries from internal clients.

Authoritative DNS edit

We run auth DNS servers for these domains:

  • toolserver.org
  • wita.toolserver.org
  • 0.23.10.in-addr.arpa (reverse DNS for 10.23.0/24)
  • 1.24.10.in-addr.arpa (reverse DNS for 10.24.1/24)
  • 192-223.174.198.91.in-addr.arpa (reverse DNS for 91.198.174.192/27)

Except for wita.toolserver.org, these are all served by BIND. The primary server is a.ns.toolserver.org (turnera); secondaries are b.ns.toolserver.org (damiana) and c.ns.toolserver.org (amaranth).

The zone files are in /etc/opt/ts/namedb/master/ on turnera. After editing a zone, reload it (/opt/ts/sbin/rndc reload toolserver.org) or restart named (svcadm restart named).

toolserver.org is DNSSEC-signed. This means that after editing the zone file, you need to run zonesigner toolserver.org before you reload the zone. If you don't do this, your changes will not appear.
