How do you do nslookup for a domain?

To perform an nslookup for a domain, open your command line interface (Command Prompt on Windows or Terminal on macOS/Linux) and type nslookup, followed by the domain name you want to query (e.g., nslookup example.com). Press Enter, and the tool will return the IP address associated with that domain, along with other DNS information. You can also specify a DNS server by appending its address after the domain (e.g., nslookup example.com 8.8.8.8 for google's DNS).
