I don't know too much about RBL DNS servers, but changing the number
sequence around for an IP should be pretty easy:

#!/bin/sh

IP='192.168.1.2'
echo $IP|sed -r
's/^([0-9]+)\.([0-9]+)\.([0-9]+)\.([0-9]+)$/\4.\3.\2.\1/'

Essentially, it performs a regular expression replace. It finds the four
groups of numbers and reverses the order (#4 goes first, #3 second,
etc.).
