performed, so that with nonzero target-fetch-policy it fetches forwarder addresses and uses them from cache. Also updated that delegation point cache fill routines use CDflag for AAAA message lookups, so that its negative lookup stops a recursion since the cache uses the bit for disambiguation for dns64 but the recursion uses CDflag for the AAAA target lookups, so the check correctly stops a useless recursion by its cache lookup.
Unbound
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. Don’t 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. If building from the repository source you also need flex and bison 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 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.
