unbound
A validating, recursive and caching DNS resolver
Unbound is a validating, recursive, and caching DNS resolver. The C implementation of Unbound is developed and maintained by NLnet Labs. It is based on ideas and algorithms taken from a java prototype developed by Verisign labs, Nominet, Kirei and ep.net. Unbound is designed as a set of modular components, so that also DNSSEC (secure DNS) validation and stub-resolvers (that do not run as a server, but are linked into an application) are easily possible.

Use flags of 1.25.2
- debug Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
- dnscrypt Enable DNSCrypt support
- dnstap Enable dnstap support
- +ecdsa Enable ECDSA support
- ecs Enable EDNS client subnet support
- gost Enable GOST support
- +http2 Enable HTTP/2 support for DoH via net-libs/nghttp2
- python Add optional support/bindings for the Python language
- redis Enable cache db backend which uses dev-libs/hiredis
- selinux !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
- static-libs Build static versions of dynamic libraries as well
- systemd Enable use of systemd-specific libraries and features like socket activation or session tracking
- test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
- +tfo Enable TCP Fast Open client+server
- verify-sig Verify upstream signatures on distfiles
