Unbound

Github Build Status Packaging status Fuzzing Status Documentation Status Mastodon Follow

Unbound is a validating, recursive, caching DNS resolver. It is designed to be fast and lean and incorporates modern features based on open standards. If you have any feedback, we would love to hear from you. Dont hesitate to create an issue on Github or post a message on the Unbound mailing list. You can learn more about Unbound by reading our documentation.

Compiling

Make sure you have the C toolchain, OpenSSL and its include files, and libexpat installed. Unbound can be compiled and installed using:

./configure && make && make install

You can use libevent if you want. libevent is useful when using many (10000) outgoing ports. By default max 256 ports are opened at the same time and the builtin alternative is equally capable and a little faster.

Use the --with-libevent=dir configure option to compile Unbound with libevent support.

Unbound configuration

All of Unbound's configuration options are described in the man pages, which will be installed and are available on the Unbound documentation page.

An example configuration file is located in doc/example.conf.
