Perhaps you've heard of IPv6 [snip]
Perhaps you've heard of turd polishing?
Find something that supports IPv6 that isn't a security nightmare. They exist. Isn't that your job as a netadmin, anyway? It's because of lazy-assed admins that keep following turds like BIND -- religiously -- that it remains #1 in market share when it should have been kicked to the curb long ago for being the bloated, slow dog that it is.
And I think I've already made my point about the relative easy[sic] [snip]
Security isn't always easy. You've made your deal with devil. Tell me all about it when he calls the tune and your BIND box gets rooted on a weekend or while you're on vacation.
Even if you *did* have to do something custom for a BIND alternative, you only have to do it once and never worry about it again. You make it sound like you have to write the daemon yourself from scratch. Lazy.
Enjoy your patch cycle and watching over your shoulder while I enjoy restful sleep.
