8 Unbound is a validating, recursive, caching DNS resolver. It is designed to be
9 fast and lean and incorporates modern features based on open standards. If you
10 have any feedback, we would love to hear from you. Don’t hesitate to
11 [create an issue on Github](https://github.com/NLnetLabs/unbound/issues/new)
12 or post a message on the [Unbound mailing list](https://lists.nlnetlabs.nl/mailman/listinfo/unbound-users).
13 You can learn more about Unbound by reading our
14 [documentation](https://unbound.docs.nlnetlabs.nl/).
18 Make sure you have the C toolchain, OpenSSL and its include files, and libexpat
19 installed. Unbound can be compiled and installed using:
22 ./configure && make && make install
25 You can use libevent if you want. libevent is useful when using many (10000)
26 outgoing ports. By default max 256 ports are opened at the same time and the
27 builtin alternative is equally capable and a little faster.
29 Use the `--with-libevent=dir` configure option to compile Unbound with libevent
32 ## Unbound configuration
34 All of Unbound's configuration options are described in the man pages, which
35 will be installed and are available on the Unbound
36 [documentation page](https://unbound.docs.nlnetlabs.nl/).
38 An example configuration file is located in
39 [doc/example.conf](https://github.com/NLnetLabs/unbound/blob/master/doc/example.conf.in).
