IPv4 vs IPv6: What's the Difference?

The internet is running out of IPv4 addresses. This is why the transition to IPv6 is critical.

IPv4

IPv4 uses 32-bit addresses, allowing for about 4.3 billion unique addresses. Example: 192.168.1.1.

IPv6

IPv6 uses 128-bit addresses, providing a virtually infinite number of addresses. Example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

Key Differences

• Address Space: IPv6 is vastly larger.
• Security: IPv6 was designed with security in mind (IPsec support is mandatory).
• Efficiency: IPv6 simplifies packet processing by routers.
