FAQ

How are the data available?

Data are available via rsync as gzipped rbldnsd or BIND zone files, CSV or JSON files, or by private DNS query.

When a given host has multiple classifications, how is that represented?

A separate response for each classification is returned.

How are domains reduced?

Domains are reduced using Mozilla Public Suffix List with ICANN and Public Suffix List extensions. For use as DNS queries, no reduction is needed since domains are listed with wildcards which match domains and all their subdomains.
