We're working through some DNS transitions at the office. On Friday I spent too long looking for a slick way to use record generators or something similar in BIND to create forward DNS entries for 750 addresses that I needed to create. It wasn't until too much later that i realized the simple solution.... It takes a few seconds to use Excel to create the records. Simply set up the first two records with sequential numbers in them and then copy away. It has to be done once for each subnet, but in a few seconds all 750 addresses were done.
