Frontier DNS Services

Reverse DNS

We will modify reverse DNS for Business Class DSL and Dedicated Internet customers [BDSL/SDSL/FND/ABCS] who have static IP addresses assigned to them. We are not able to modify reverse DNS for ADSL or Dialup customers.

For Dedicated Internet and Cyber Center customers we will delegate Frontier assigned IP space to your name servers on request for /24 netblocks and larger.

If you have a Frontier-assigned IP netblock smaller than a /24 (less than 255 addresses) Frontier will host the reverse DNS records (PTR's) of the subnet for you. Send an e-mail to with names and IP addresses.
