-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2020-3cfd38fefd 2020-05-24 03:27:16.087566 --------------------------------------------------------------------------------
Name : unbound Product : Fedora 32 Version : 1.10.1 Release : 1.fc32 URL : https://nlnetlabs.nl/projects/unbound/ Summary : Validating, recursive, and caching DNS(SEC) resolver Description : Unbound is a validating, recursive, and caching DNS(SEC) 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.
