DNS servers in China are a web server designed to connect with a massive database that stores all information about domain names and their corresponding DNS records.
These records include the registrant of the domain name, the hosting, active name servers and other information.
A domain name’s DNS servers are listed in the WHOis database and the hosting control panel, and appear as NS1.NAMESERVER.COM and NS2.NAMESERVER.COM.
There are thousands of DNS servers around the world containing pieces of the database. However, there are only 13 root DNS servers for China containing the total database on each server.
There are 2 types of DNS servers – primary and secondary. However, it’s necessary to notice that any DNS server can be used as a primary or a secondary server, depending on the preference of the sever administrator. It’s possible to have the same server that works as a primary server for one zone and a secondary server for another.
Primary master DNS servers
A primary master name server reads data for the domain zone from a file located on the web server of the hosting account. This server often sends information to the secondary server as well.
Zone data is the information specified by the server administrator telling the server how to communicate with other servers. When a primary server communicates with a secondary server, it’s called a zone transfer because zone data is being transferred from one DNS to another.
2 DNS are assigned to each domain to make administration easily and provide more security than a single server. Once zone data is created for a main server, it doesn’t need to be copied over to the secondary server because the 2 servers share zone data automatically.
Secondary DNS Servers
A secondary DNS server receives zone data from the primary server automatically after starting. In Microsoft’s DNS manager software, secondary China server DNS is referred to as the secondary. Every time a secondary server features, it requires information from its master server.
It’s essential to notice that a secondary server doesn’t need to pull data form a main server because another secondary server can be installed as the master server.
Secondary DNS servers are just as important as main servers because they provide security in the form of redundancy. They also lessen the load placed on the main server and make sure that there is a server working to deliver data. By diversifying the administrative structure of DNSs, the security of websites and the internet in general is guaranteed.
