Favorite DNS?

[Steven Alligood]

I agree with a couple of these other guys that BIND is an important 
skill to know if you want "admin" on your resume.  It is widely used, 
and does a great job of everything you will want for DNS up to a few 
thousand zones.

At that point, it becomes slow to start, since it has to read in every 
zone during it's start, and management can become cumbersome.  I have 
used bind up to about 120,000 zones, and it would take about an hour to 
start.  Once started, it worked fine for a while, then would pound 
memory, or have odd hiccups, etc.

We moved to MyDNS, since everything is in mysql, with a MyDNS cache and 
a mysql cache, most of the well-used zones are always ready, and it 
starts in about 2 seconds.  That is saying something since we now have 
over 330,000 zones in it.  It is an incredibly good DNS server for that 
many records.  It is more work than BIND since you have to deal with 
mysql as well, but worth it for the advantages in handling large amounts 
of zones.

Of course, that is just for authoritative.  MyDNS isn't a resolver.  For 
resolvers, I haven't found anything that will do better than BIND 
(assuming you don't use the Redhat version, it's terrible).

I would suggest BIND for small installs, and MyDNS for large.  If you 
want to play with those lesser used DNS servers, go for it, but keep in 
mind that BIND is a resume builder; the rest are not.  And BIND will do 
everything you need or want.
