DNS server with MySQL Backend

[Bob Pierce]

Just a quick question, 
Does anybody know of a good DNS server with MySQL backend? 
We're currently looking at MyDNS. 
Has anybody had any experience with MyDNS or other MySQL driven DNS
servers under heavy load? 
Also, can anybody recommend a good DNS benchmarking utility? 
Thanks for your help, 
Bob.
