IPv4 vs IPv6: What's the Difference?

IPv4, the original internet addressing system, simply ran out of unique addresses to assign as the internet grew — IPv6 was built to solve that permanently.

The Core Difference

IPv4 addresses (like 192.0.2.1) support about 4.3 billion combinations — vastly insufficient today. IPv6 addresses are dramatically longer, supporting effectively unlimited unique addresses.

Does It Matter for Your Website?

Most hosting, including CyberNet's, supports both. Visitors reach your site correctly regardless of which protocol their device uses, since the transition happens transparently.

Why Full Adoption Has Taken Time

IPv6 isn't backward-compatible with IPv4, requiring infrastructure on both ends to support it — which is why both protocols continue operating side by side today.
