Auto reverse is the default option that works by AAISP filling in a PTR record for each IP4 address and a corresponding forward A record as well so that all of your IP addresses will have a valid reverse entry automatically. This is mainly for customers who are not interested in setting up any reverse entries but need something in place to avoid problems with some servers. If you also use A+reverse records in a domain then your IPs will have two PTR records, both valid.
Most ADSL customers will have a small block of IPs which they can delegate using CNAME if they want. However all ADSL lines also have a single IP address for the external (WAN) side of their [[ADSL Router|ADSL router]]. This is always delegated as a single zone for the IP address.
Where you have a domain that we manage in our DNS, and want an IP we manage to refer to and from that name. To do this you can create an A+reverse record or an AAAA+Reverse in your domain DNS entries (instead of simply an A or AAAA record). This will automatically complete the corresponding reverse entry in our DNS mapping the IP address back to the name.This is usually the simplest way to handle reverse DNS when you also have a domain with us.
