Target version:v6.7
Resolution: NEEDINFO:No

Description

Some DNSBLs limit the maximum number of queries coming from the same ip address. All common public DNS servers and ISP servers are usually blocked.
To overcome this limitation, we need a recursive non-forwarding resolver: unbound is the best candidate.
Dnsmasq will redirect certain queries for DNSBLs to unbound non standard port 10053.
