Download Unbound 1.16.3

When you perform a DNS lookup, a recursor initially starts by asking the lookup query to a DNS root server. It can then redirect to other servers, from where it can redirect to other servers and so on, until finally a server is reached that knows the answer or knows that the look-up is not possible. The latter can be the case if the name does not exist or the servers do not respond. The process of traversing several authoritative servers is called recursion. Unbound is a dns recursor with support for modern standards such as Query Name Minimization, Aggressive Use of Dnssec-Validated Cache and authority zones. The developers have released version 1.16.3 and a security vulnerability has been fixed.
