IPv6 addresses are the new domain hacks

Kevin Murphy, June 8, 2011, Domain Tech

It’s World IPv6 Day today, and a number of companies have decided to get a little playful with their new IP addresses, using them to spell out their brands.

IPv6 uses hexadecimal notation ā€“ the 10 digits and the letters A through F ā€“ so it’s possible to use them as “vanity” addresses using something like h4x0r-speak or license plate hacks.

Here’s a few IPv6 “hacks” I’ve found in AAAA records so far today:

BBC – bbc.net.uk – 2001:4b10:bbc::1

Facebook – facebook.com – 2620:0:1c18:0:face:b00c:0:3

Cisco – cisco.com – 2001:420:80:1:c:15c0:d06:f00d (Cisco dog food)

F5 Networks – f5.com – 2001:19b8:101:2::f5f5:1d

US Department of Commerce – commerce.gov – 2610:20:0:20:5ec:d0c:d0c:d0c

A few more, such as Daily Kos’ 2001:48c8:1:c::feeb:beef, seem deliberate but don’t seem to pertain particularly to the site’s brand.

I don’t think anybody’s going to use these addresses to navigate, but I suppose they make prove useful mnemonics for address administrators within those companies.
