Web Addresses

In the real world, we use physical addresses to help us find where a friend lives, where a business is located, or where a party is being thrown (well, I don't because I'm not invited to parties, but I digress).

In computing, web clients find other computers over the internet using Internet Protocol (IP) addresses. Each device connected to the internet has a unique IP address.

Domain Names and IP Addresses

When we browse the internet, we type in a human readable domain name. That domain is converted into an IP address. The IP address tells our computer where the server is located on the internet.

An IP address typically looks like a sequence of numbers separated by periods, ranging from 0 to 255.

Assignment

Cloudflare is a tech company that provides a cool HTTP server that we can use to look up the IP address of any domain.

I've provided a fetchIPAddress function that uses the fetch API to communicate with Cloudflare. The function takes a domain name as input and should return the IP address associated with that domain.

On line 12, the function is simply logging the entire object we receive from Cloudflare to the console. Run the code to see the structure of the object.
Update the code to return any one of the IP addresses from the response object, and remove the logging.

Troubleshooting

Failed to fetch - If you are having difficulty running this assignment make sure your browser is not blocking requests to third party domains!
