It’s World IPv6 Day today!
For those of you who don’t know, IPv6 is the next-generation Internet protocol, which offers a large number of IP addresses,
79228162514264337593543950336) times of what IPv4 has to offer. A typical IPv6 address looks like
2001:db8:cafe::1, compared to an IPv4 address
192.168.148.1. IPv4 space is quickly becoming exhausted, necessitating the migration to IPv6. You can read more about IPv6 in its Wikipedia entry or in the free book, The Second Internet. You can use IPv6 tunnels if your ISP does not offer IPv6 connectivity yet.
You can test your own IPv6-inessand see if you make the grade.
Bummer, I’m not on IPv6 right now. Today would be the day for it.
