Software update: Knot Resolver 3.2.1

Jan

2019

Knot Resolver is an open source dns recursor written in C and LuaJIT. When you run a dns look-up, a recursor initially starts asking the look-up question to a dns root server. This can then refer to other servers, from where it can be redirected 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. This can be the case if the name does not exist or the servers do not respond. Knot Resolver is for example used by Cloudflare for their 1.1.1.1 dns service. The developers of CZ NIC have released version 3.2.1 with the following modifications:
