IPv6 Day a success, comparatively speaking

Efforts to raise awareness of the need to move to the new Internet protocol version 6 (IPv6) through "IPv6 Day" were broadly seen to be successful with a big jump in traffic as people were encouraged to make the transition from the old IPv4 system.

However, the amount of traffic of the Internet using IPv6 remains tiny overall, representing just 0.1 percent (although that is an improvement on last year's 0.02 percent). The move to IPv6 is becoming increasingly important, warn Internet engineers, as addresses on the old IPv4 system slowly run out.

However, due to the fact that IPv6 is not compatible with IPv4, many companies are putting off the additional expenditure of moving to IPv6 until they have no other choice.
