What is this?
An IP address can be compared to a phone number. It allows computers to exchange data over the Internet as a human would phone another knowing his phone number.
To get IP addresses, computers ask the Domain Name System (DNS) to resolve human-readable names (eg: dnstoolkit.net) into an IP address. Like a Phone book would allow you to "resolve" a family name into a phone number. More about DNS lookup on the dns lookup page.
