How do I set up reverse DNS for my IPs?
Use the Reverse DNS link located in the Main Menu of the Portal (https://portal.arpnetworks.com). You can create, modify and delete PTR records for your IP(s).
You may also delegate reverse DNS to your own name servers by creating NS and/or CNAME records. This does not require using RFC 2317.
If you do want to use RFC 2317, we can set up the delegation for you manually.
