Domain Name System is a crucial part of the internet. It is the system that harnesses your communication between you and your computer. When you type a domain name, the system converts it into an IP address that the server can use to search for it in the network. The system saves you from the complicated task of memorizing IP address which is in the form of numbers. The DNS system consists of servers that store information of various domain names and their domain records. In another word, these servers are known as nameservers or DNS servers. Several types of DNS servers are available and perform a different task. Here are the top three types of Domain Name Servers:
Zone Master Server
This server consists to date of domain names and DNS records for a particular region. It is a point of contact for a person searching for information in a specific zone. Due to this, it’s an authoritative server as it is a database for websites in a given location where every computer in that area routes. For instance, there can be Zone master servers for North America, Central, and South America. Also, zone master servers exist for Europe, Africa, Asia, and Australia. This server consists of a primary master server and secondary slave servers.
Caching-only name server
As the name suggests, this name server function is caching. This server stores information of query results. When you search for the information in future, you will not have to wait as no DNS lookups will happen. The caching-only name servers are only permitted for queries only. The essence of this server is to make faster future searches. So, it is an essential component in harnessing your website loading speed.
This server is the foundation of the DNS system. It is the initial point of translating a domain name into an IP address. The role is DNS namespace resolving. The main function of root servers is receiving requests and directing the TLDs servers. Also, they publish the website files on the internet. Hence, this server is essential in initializing computer network communications.
As you can see, several types of DNS servers exist. Each of this server has its unique role in facilitating the accessibility of the content on the internet. As a site owner, you need to understand how the name server works to enhance your DNS management.
