Re: A good read and a question

There will definitely need to be some code updates for this to work. I've
had the same thought in the past and every device I've tried to configure
in this range has rejected it. This includes network gear and servers.

Rack1R1(config-if)#ip address
*Mar 4 20:06:20.013: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Loopback99
9, changed state to up
Rack1R1(config-if)#ip address 240.1.1.222 255.255.255.0
Not a valid host address - 240.1.1.222
Rack1R1(config-if)#
Rack1R1(config-if)#

A few minutes back I was day dreaming about the good old IPv4 Address
classes ;-) and a thought flashed my mind that the 240.0.0.0/4 class E has
always been reserved for future use. I then thought when would this future
arrive when we already have the IPv4 space almost depleted .. A google
search led me to this URL which does have certain information on how this
address space can/shall be used .

http://tools.ietf.org/html/draft-fuller-240space-02

While this is a good read , has anyone in here really had a chance to use
or
work on this address space..If yes, where and how ? how does the router
behave for such IP addresses ?
