IPv4 vs IPv6: The Future of the Internet

What is an IP Address?

Every device on the internet has a unique IP address, similar to a home address.

The Problem with IPv4

IPv4 addresses are nearly exhausted. There are only 4.3 billion possible addresses — not enough for every device.

IPv6 as the Solution

IPv6 offers 340 undecillion addresses. That's enough for every device until the end of time.
