NXDOMAIN Resolvers

Wed Apr 20 09:07:09 UTC 2022

Good morning,
I am currently analysing the DNS resolvers (local and public ones) in terms
of protection and performance (in particular their speed).
I noticed that, in case of a malicious domain name, some local resolvers
send an NXDOMAIN and others a courtesy page address. Do you know if the
resolvers (for example TIM, Wind or Fastweb) can return an NXDomain in
order to protect their clients?

Thanks a lot
