I am sure it has come up a number of times, but with IPv6 you can
make up fancy addresses that are (almost) complete words or phrases.
Making it almost as easy to remember as the resolved name.

It'd be nice in a weird geek sort of way (but totally impractical) to
be able to request IPv6 blocks that have some sort of fancy name of
your choice.

2001:db8:dead:beef::
dead:beef::
dead::beef

As seen on http://en.wikipedia.org/wiki/Magic_number_%28programming%29
"DEADBEEF     Famously used on IBM systems such as the RS/6000, also
used in the original Mac OS operating systems, OPENSTEP Enterprise,
and the Commodore Amiga. On Sun Microsystems' Solaris, marks freed
kernel memory (KMEM_FREE_PATTERN)"

Bonus points if your organisation's name only contains HEX characters.

Not quite dead beef, but spotted this when testing connectivity using
a site from one of the rackspace guys:

ipv6.icanhazip.com.    7200    IN    AAAA   
2001:470:1f10:d57:feed:beef:cafe:d00d

like c15c:0d06:f00d seen on ipv6 day (tail end of cisco's website v6
address) (among several others with lots of deadbeef's and cafe's)
