“Perfection is achieved, not when there is nothing more to add,

Deadwood is MaraDNS 2.0’s recursive resolver. As part of MaraDNS, it is
open-source, released under a BSD-style license.
Its goal is to be tiny—it is the smallest cross-platform currently maintained
DNS server. The binary can be 64k in size.
Deadwood is a complete from-the-ground rewrite of MaraDNS’ recursive
DNS server, sharing no code with MaraDNS. The design is by and large
the same (for example, the notes in the PDF document The Hitchhiker’s
Guide to DNS cache poisoning about MaraDNS 1.3.07 also apply to Deadwood),
except that Deadwood does not use threads.
The current stable version of Deadwood can be
downloaded from the “Stable” directory. Some other
resources, including documentation are also available.
Here is a listing of files here:
IMPORTANT: Like MaraDNS, I do not
support Deadwood via private email.
The "stable" directory has the most recent release of Deadwood.
The .tar.bz2 file is the CentOS 5 and Windows source code; the .zip
file is the Windows 7 binary.
There is a supplied document (Vista.txt) that describes one way
to get Deadwood to run in Vista and Windows 7.
The "tiny" directory has an older (but still maintained with security
and other critical updates) version of Deadwood which has fewer features
than newer versions of Deadwood, but has a smaller binary and works
well as a DNS load balancer (either with or without caching). Only use
this version if a 64 kilobyte binary is, for whatever reason, too big;
this release doesn't handle TTL aging correctly, which, in light of the
"Ghost Domain" attack, has security implications.
Deadwood 3.2 is MaraDNS 2.0's recursive resolver.
