What Are Servers That Host Part of the Domain Name System Called?
The Domain Name System, or DNS, is the phone book of the Internet. It’s a distributed database that contains the mapping of domain names to IP addresses.
This system is essential to the proper functioning of the Internet.
Each time you type a domain name into your web browser, your computer contacts a DNS server to look up the IP address for that domain. The DNS server then responds with the IP address, and your browser connects to the website associated with that IP address.
DNS servers are just like any other type of server; they are computers that are connected to the Internet and store data. The data they store is the mapping of domain names to IP addresses.
When you type a domain name into your web browser, your computer contacts a DNS server and asks for the IP address associated with that domain.
There are many different types of DNS servers, but they can generally be divided into two categories: recursive and authoritative.
Recursive DNS servers
Recursive DNS servers are also called caching DNS servers because they keep a cache of recent queries and responses. When your computer contacts a recursive DNS server and asks for the IP address for a particular domain, the server will check its cache to see if it already has the answer. If it does, it will simply return the IP address from its cache.
Authoritative DNS servers
Authoritative DNS servers are also called name servers because they store data about specific domains. When your computer contacts an authoritative DNS server and asks for the IP address for a particular domain, the server will look up the answer in its database and return it to your computer.
In conclusion, when you type in a domain name, your computer contacts either a recursive or authoritative DNS server in order to find out whatIP address is associated with that domain. Recursive servers keep a cache of recent queries while authoritative servers have databases containing information about specific domains.
