A name server is a Domain Name System (DNS) server that serves DNS records for a domain. DNS records are often used to specify server IP addresses for domains.
When you type in digitalocean.com
into your browser’s URL bar, the browser sends a request to local DNS servers, known as DNS resolvers, asking for the IP address of digitalocean.com
. If the resolver does not have the IP address in cache, the resolver forwards the request through a structured hierarchy of other DNS name servers to locate the authoritative name servers for digitalocean.com
and return the IP address.
When you add a DNS record to your domain on the DigitalOcean platform, you are adding the record to an authoritative name server that is responsible for storing and serving your domain’s records.
