Corporate Domain Manager:
more DNS info

Primary and secondary DNS services: You can use Concentric for your primary DNS platform, or for secondary DNS if you want to run your own DNS server.

Configure Address (A) records with DNS Manager. If you delegate your IP block to our nameservers, enabling the Pointer (PTR) flag means that the Reverse DNS resolution happens automatically, without you having to enter a separate PTR record.

Configure as many Mail Exchange (MX) records as you need with DNS Manager.

The DNS Manager Advanced Mode includes Forward Zone Transfers, so that Concentric nameservers can be "slaved" to a master nameserver for your domain, and thus receive any zone file changes made to the master for your domain name. Many other Advanced Mode commands are available.
