How to lookup SOA records

Jump to

SOA records can be configured by the owner of a domain name. They are used to store information in the DNS, which can be looked up by anyone. Each record type has a different purpose. The purpose of SOA records is to announce that a new DNS zone starts somewhere in the tree of DNS names. An example is the delegation from a top level domain (e.g. .com) to the owner of a domain name (e.g. example.com). This start of authority contains some information about the child zone, which we explain in detail in our article about SOA records.

SOA records are configured in DNS. But how can you look up these SOA records? That depends on the operating system you are using. Windows, Linux and Mac all have a different way of finding SOA records. The sections below contain instructions for each operating system.
