The DNS record type responsible for translating domain names into IP addresses is the "A record" (Address record). The A record is used to map a domain name (such as example.com) to the corresponding IPv4 address (such as 192.0.2.1).
When a user enters a domain name in a web browser or attempts to access a domain through any network application, the DNS resolver contacts the DNS server to resolve the domain name into an IP address. The DNS server looks up the A record associated with the domain name and returns the IP address to the resolver. This IP address is then used to establish the necessary network connection to reach the desired web server or network resource.
A typical A record consists of two essential components:
1. Domain Name: The domain name for which the A record is being created. For example, "example.com" or "
www.example.com".
2. IPv4 Address: The corresponding IPv4 address linked to the domain name. It is represented as a series of four numbers separated by periods, such as "192.0.2.1".
In addition to the A record, there are other DNS record types that serve different purposes, such as AAAA records for IPv6 addresses, MX records for mail server configuration, CNAME records for aliasing one domain to another, and more. Each record type has its own specific use in the DNS system, but the A record is primarily responsible for the translation of domain names to IPv4 addresses.
