The answer is the Domain name System. Websites can register their IP addresses under a domain name (e.g. Facebook.com). When you search for this, your computer searches for that domain and retrieves its IP. After that, it takes you to the requested website.

The IP headers on data packets determine which IP the packets will go to.
