[address-policy-wg] IPv4 reserved space

Yuri,

I wouldn't have a difficulty with it :) ...   I dont see a reason why it
wouldnt work ... although you would want everyone who is filtering bogons
manually from their routers and the 240.0.0.0/4 has been considered a bogon
for quite some time...  so alot of people who do rudimentary prefix
filtering on their border routers would have to update to make that range
usable ...  I have heard arguments that some Operating systems have that
range filtered out  and is non configurable...

but I doubt the IPv6 adoption advocates ...  or the IPv4  Sellers would
like that idea too much as it would cause the price per ipv4 to
collapse...


I reckon this question has been asked before and I'm sure someone will
point us to that discussion before...

Hope this helps,
