Zone resource records

Using the DNS Manager, you can define resource records to hold the following information about a zone:

• Mail exchangers and their relative priorities (MX records). These are the machines that normally handle mail sent to this domain.

• The administrator for the zone (RP record).

• A description of the hardware and operating system of the host machine for the master server (HINFO record).

• A free-text description of the zone (TXT record).
