Abstract
The configuration and maintainance of DNS zones offer many degrees of freedom and thus several opportunities for making mistakes. Most DNS zones today are small and have to be set up and maintained by non-experts.
1. Conventions used in this document
Domain names used in this document are for explanatory purposes only and should not be expected to lead to useful information in real life [RFC 2606].
2. Background
Various DNS surveying activities show that the vast majority of today's DNS zones are populated by very few hosts. In most cases there is only an HTTP server announced under the common name "www", sometimes accompanied by distinct mail or DNS servers or a bastion host.
4. Remarks and Explanation
The values presented in the example.com SOA RR are discussed in detail. One main goal was to provide for fixed cut-and-paste values wherever possible instead of intervals to reduce the chance of operational problems caused by unfortunate combinations.
4.1 The MNAME Value
The DNS specification explicitly states that the primary master server be named here. The value must be determined and used. Especially it is a mistake to repeat the zone name here, unless this also leads to a valid address of the primary master.
4.2 The RNAME Value
The RNAME is to publish a mail address of a person or role account dealing with this zone with the "@" converted to a ".". The best practice is to define (and maintain) a dedicated mail alias "hostmaster" [RFC 2142] for DNS operations.
4.3. The Serial Number
The most important issue is that this value be incremented after any modification to the zone data. For debugging purposes it has shown to be helpful to encode the modification date into the serial number.
