==1. Auto Reverse (The Default)==
Auto reverse is the default option that works by AAISP filling in a PTR record for each
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.
e.g.:
if you have the IPs <code>192.0.2.1</code> and <code>2001:DB8::1</code> reverses will be created of:
<code>1.2.0.192.in-addr.arpa</code>
<code>1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa</code>
