For IPv4 and/or IPv6 domains

Stable release: DNSdoctor-1.0.1

Why DNSdoctor?

The DNS is a critical resource for every network application (mail, web, ...), and so it is quite important to ensure that a zone or domain name is correctly configured.

The DNS has been designed to be robust to errors, as a result you can pervert it so to have a working DNS even if you misconfigured it. But in such a case, a single additional error can result in your zone completely disappearing, and this additional error is not necessarily your fault!

So if you don't want to disapper from the Internet with emails and web servers due to, for example, one of the nameserver you use but don't manage, don't mess your initial configuration and use DNSdoctor to check your domain!

How can DNSdoctor help?

DNSdoctor is intended to help solving misconfigurations or inconsistencies. It will help you by looking for potential errors and give you a description of the problem and refere you to RFC or other documents; but of course it is still recommanded that you have some basic knowledge of how the DNS works.

The DNSdoctor configuration file reflect the policy to use. You can let it select the best test set to apply when checking a zone (use of a reverse delegation profile for .ip6.arpa or .in-addr.arpa, and a generic profile for other TLDs); but on the other hand, you can also force the use of a particular profile or create a new one (for example to test RFC compliance).
