If all you're after is DNS hosting, check out cloudflare.com. They offer DNS hosting as part of their free CND setup. I'm using it for all of my websites, super simple interface, but offers all the DNS features you'd ever need.
EDIT: OK, that'll learn me to not visit the website first… Apparently they aren't offering DNS hosting.. HODOR!!
