The goal is to plug in a domain name in the browser using Javascript and then to get out the IP address of that domain. For example, if I use https://www.whatismyip.com/dns-lookup/ to do it, I plug in netflix.com and I get IP address 3.211.157.115.

I've been able to do this with Python code fairly easily using the socket library.

import socket
domain = "..."    
ip = socket.gethostbyname(domain)

How can I do this in the browser using Javascript, preferably without using any APIs?

Does this answer your question? [Can I perform a DNS lookup (hostname to IP address) using client-side Javascript?](https://stackoverflow.com/questions/102605/can-i-perform-a-dns-lookup-hostname-to-ip-address-using-client-side-javascript) – Yevhen Bondar Dec 29 '21 at 18:40

There is nothing built into browser to do this. Would require an API. Make a request to your python server and do the ip lookup from there – charlietfl Dec 29 '21 at 18:40
I'm going to try and use my own Python server. Do you know which external API would be best if I end up using one? – George Adams Dec 29 '21 at 18:41
What's wrong with the one you are using with your python? Searching for such API's should be easy using your favorite search engine – charlietfl Dec 29 '21 at 18:46
There's nothing wrong. It's just that I'm making a chrome extension and therefore cannot use Python, so I was trying to do it using Javascript – George Adams Dec 29 '21 at 18:48
Look at DoH that standardizes DNS queries over HTTPS. – Patrick Mevzek Dec 29 '21 at 19:15
