→1. Auto reverse (The Default)
|
There are a number of ways to do this...
==1. Auto
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.
