DNS Service Overview
The Domain Name System (DNS) is a distributed database that maps IP addresses to domain names so your clients can find the resources by name rather than by numerical address.
If you don't have an ISP to handle DNS requests for your network and any of the following is true, you need to set up DNS service:
- You don't have the option to use DNS from your ISP or other source.
- You plan on making frequent changes to the namespace and want to maintain it yourself.
- You have a mail server on your network and you have difficulties coordinating with the ISP that maintains your domain.
- You have security concerns regarding giving your network's computer names and addresses to an outside organization (your ISP).
