What is a PTR record?

What is a PTR (pointer) record?

 

A pointer record* resolves an IP-address to a fully qualified domain name (FQDN).

This is an example of a PTR record:

Entry Type

IP Address

Entry Name

PTR

192.168.1.1

Mail.mydomain.com

 

Why use a PTR?  Some companies use this as part of their security protocol.

A pointer record’s main use is to check whether a server name matches/associates with the IP address from where the connection was initialized.

 

To request a PTR record customer has to either contact our technical support team or send the following information to a moderator at the Comcast Business forum community.

  1. Full Name
  2. Account Number
  3. DNS Entry 
    1. EX: xxx.xxx.xxx.xxx  àmydomain.com.

 

* PTR records are also called Reverse DNS records.  To learn more about DNS, click here.
