We didn't choose it.  ARIN and other RIRs started handing
out that space, 
and if you didn't like it you were welcome to not have any
more IP space.

There's a huge difference between getting a handful of
networks to fix 
their outdated filters and getting "the internet"
to all upgrade their 
software or replace old non-upgradable gear.

Lots of 2500s can't run that code.  Where can I get a 240/4
compatible 
update of c5200-is-l.113-11a.AA.bin?

Interestingly, my unpatched Ubuntu 7.04 notebook would let
me install 
routes for networks in 240/4, but would not let me configure
an interface 
IP in 240/4.

although this is not linux-l , here is a hint for those
who keep
trying:

# /sbin/ifconfig eth1 240.1.2.3 netmask 255.255.255.0
SIOCSIFADDR: Invalid argument
SIOCSIFNETMASK: Cannot assign requested address
SIOCGIFADDR: Cannot assign requested address
SIOCSIFBROADCAST: Cannot assign requested address
# /sbin/ip add add  240.1.2.3/24 dev eth1
# /sbin/ip add show eth1
3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500
qdisc pfifo_fast qlen 1000
    link/ether 00:30:48:5d:0a:af brd ff:ff:ff:ff:ff:ff
    inet 240.1.2.3/24 scope global eth1

Now using this IP with the binaries that are of the same
vintage as
ifconfig(), that's really a discussion for linux-l .
