Abstract

This memo describes errors often found in DNS data files. It points out common mistakes system administrators tend to make and why they often go unnoticed for long periods of time.

Introduction

Due to the lack of extensive documentation and automated tools, DNS zone files have mostly been configured by system administrators, by hand. Some of the rules for writing the data files are rather subtle and a few common mistakes are seen in domains worldwide.

This document is an attempt to list "surprises" that administrators might find hidden in their zone files. It describes the symptoms of the malady and prescribes medicine to cure that. It also gives some general recommendations and advice on specific nameserver and zone file issues and on the (proper) use of the Domain Name System.
