Script to add IPV6

Hey Guys, I am wondering if anyone has written a bash script to add IPV6 to all their vips. I want to do dual stack on most if not all of my vips so since you need to recreate the vip with a new address, I was thinking about a script to do this and wondering if anyone already has one that they would be willing to share. I have done some bash automation scrips in the past to create sets of vips, but nothing with this many variables.

Thanks

Joe
