For this purpose, this type of DNS record receives various types of information.ĭNS records generally consist of several fields. The way the zone transfer is supposed to proceed is regulated by the SOA record. servers situated lower on the hierarchy) synchronize their data with that of the “master” server. In order for the zone files to remain current on all servers, a zone transfer must be performed regularly. ![]() Instead of shouldering the load for all requests, the requests are distributed among different devices. The SOA record is especially important in the case of server clusters. The record accordingly provides information on a number of issues, such as whether or not the addressed server is even responsible for the request. In order to establish the different authorities, each zone file must contain an SOA record. ![]() ![]() These are simple text files in which all of a zone’s DNS records are listed. For this purpose, the DNS server administers zone files. The DNS is a decentralized, hierarchical system: Name servers don’t supply information to just any server on the internet, but to those located in an allocated zone.
