Can't access some websites using their IP address

I have windows 10.

To get the IP address of some website I type ping somewebsite.com in cmd.

For example if I say ping google.com, cmd shows Pinging google.com [216.58.206.206] with 32 bytes of data: and some lines after that. If I type that IP provided (216.58.206.206), that gets me to Google.

But some websites aren't like this. For example for website codeforces.com I get 213.248.110.126, but this doesn't get me to the website, instead shows some error 404 Not Found .

Why it doesn't work and what is the best method to get IP addresses of websites in Windows 10?

Thanks.
