DNS and Bind is traditionally the 'DNS Bible', the one book that people turn to as a DNS reference.

This domain -- DNSbook.com -- was originally purchased to promote a DNS book that never was published.
The author, however, thought that it would be nice to have an easy source to what remains the best DNS book out there.

Although DNS and Bind has not been updated in quite a few years, no other DNS book has replaced its legacy among IT professionals.
