DNS Blacklists and Whitelists

Overview

RFC 5782, “DNS Blacklists and Whitelists”, is an Informational document published in February 2010 by J. Levine. The canonical text is published by the RFC Editor.

Abstract

The rise of spam and other anti-social behavior on the Internet has led to the creation of shared blacklists and whitelists of IP addresses or domains. The DNS has become the de-facto standard method of distributing these blacklists and whitelists. This memo documents the structure and usage of DNS-based blacklists and whitelists, and the protocol used to query them. This document is not an Internet Standards Track specification; it is published for informational purposes.
