IPv6 Explained: Why the Internet Is Moving Beyond IPv4

IPv4 has powered the internet for more than 40 years, but with only 4.3 billion available addresses, it can no longer keep up with global connectivity demands. IPv6 solves this limitation with a vastly larger 128-bit address space and improved networking features.

Why IPv6?

• Massive address space: 340 undecillion possible addresses
• Native security via mandatory IPSec support
• Simplified routing with hierarchical addressing
• No need for NAT thanks to abundant public addresses

IPv6 Adoption

Adoption continues to rise as ISPs, cloud providers, and mobile networks fully enable IPv6. Google reports that more than 45% of users now access services over IPv6.
