I find it easier to talk about (or ssh into) kafka than having to remember if it's called dns1, ns1 or was it just ns.

I also trained the colleagues at our biggest customer to just add another CNAME every time they can't remember a machines real name (which'd be something like sheakkesa01). Some of those boxes have over 20 CNAMEs now, but at least they never get it wrong, not even when the pager goes off at 3am.
