1. The name service

The "name service", hereafter referred to as DNS, can be seen (in simplified terms) as a simple database that links an IP address with a name and vice versa. Each name is attached to a domain name (called a zone). There is no limit to the number of zones and the number of objects they can contain, allowing an infinite number of entities to have their own private zone.

• Presentation

  To function, the DNS service relies on servers. Each of them is the authority on a zone, and can delegate this authority to all or part of its sub-zones. For those wishing to know more about the inner workings of DNS, please refer to Gilles Guette's article
