It is a very simple but very useful example. You can use UE Studio’s Regular Expressions to catch and change anything very easily.

In order to capture an IP Adress you can use this regular expression: ^([0-9]+^).^([0-9]+^).^([0-9]+^).^([0-9]+^)

Once you capture the date, you can use ^x1 ^x2 to replace the changes so for this example in order to convert A record to PTR record, you can follow this:

Find What: ^([0-9]+^).^([0-9]+^).^([0-9]+^).^([0-9]+^)
Replace With: ^3.^2.^1.in-addr.arpa ^4

This will give change this 172.22.101.10 into this 101.22.172.in-addr.arpa 10
