I'm using Name.com as my domain registrar, and they provide all of my DNS with the registration, and I've been very happy with their service so far. (No barrage of ads or other nonsense - just to the point.) I don't believe they have any of the kinds of limits you referenced, and the prices vary by TLD and are quite reasonable. A number of years ago I used a free DNS-only service called ZoneEdit, which is still around. That was limited in number of domains and/or subdomains in some way - I don't remember the specifics. - Tony Yarusso
