IPv4 vs IPv6: The Simple Explanation

Every device on the internet needs an address. For decades, we used IPv4. Now, we are running out of those addresses, so the world is switching to IPv6.

The Main Differences

IPv4: Uses 32-bit numbers. Looks like 192.168.1.1. Limit: ~4.3 billion addresses.
IPv6: Uses 128-bit numbers. Looks like 2001:0db8:85a3.... Limit: Virtually infinite.
