About DNS Unpacked

DNS Unpacked is an independent guide to how domain names and DNS work. It is written for people who run or are setting up a website and want to understand what their registrar or host is asking them to do.

Each chapter is researched from the relevant standards (the RFCs that define DNS), official documentation from registries and DNS providers, and reference works such as Wikipedia, and cites them so you can check the details yourself.

The site carries no advertising and no affiliate links, and it does not recommend paid products.
