What is a Forward DNS Lookup?

A forward DNS lookup (also called forward DNS resolution) is the standard process the internet uses to connect you to websites. DNS stands for Domain Name System. It converts domain names, like google.com, into their corresponding IP addresses, like 142.250.74.14.

Forward DNS lookup is a 5-step process:

  1. You type a website into your browser.
  2. Your device asks a DNS server: “Which IP address corresponds to this domain?”
  3. The DNS system looks up the record.
  4. It returns the IP address.
  5. Your browser connects to that IP address and the website loads.

It’s basically the translation between domain names (the language humans use) and IP addresses (the language computers use).

The opposite of forward DNS lookup is reverse DNS lookup. Rather than starting with a domain name and translating to IP address, reverse DNS lookup starts with an IP address and translates to a domain name. You can use DNS lookup tools to find out what the domain name or IP address for a website is.
