I've just started playing with nsd, it appears very promising. It offers authoritative serving only (only primary and secondary no caching or proxying). It uses a database for all primary zones (fast startup). It seems to have been designed for security and reliability.
It has basic compatability with BIND zone files, although I suspect that it may not handle bad zone files as well (so you just have to get them right ;). I'm thinking of putting it on some of my servers in the near future. So this leaves DNS caching as the only reason for BIND. Is there a DNS server that does caching better than BIND? -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
