Re: [isp-bgp] Most inefficient use of allocation list?

[Charles Gucker <cgucker@...>]

I feel that I should mention that there are plenty of companies with
publically unique space, who do not announce the space to the global
Internet but announce the space to other companies where RFC1918
space wouldn't scale for all companies involved.  Some can use double
NAT's to get around this, but again, it doesn't scale well.

Just because a company doesn't announce it's address space globally
does not mean it's not being responcible with the space.
