Re: Rogers Canada using 7.0.0.0/8 for internal address space

This is the business reality of the IPv4-scarce era.  Diluted IPv4 is
not new to many places and will become common in many more places.
Furthermore, it is a calculated business risk.  IPv4 services
will/have become the 2nd class (NAT444...)  services as IPv6 ascends
to first class status with e2e restored and more and more services
supporting IPv6 (World IPv6 day in a little over 2 week!...).


Diluted IPv4 is one thing. Hijacking space allocated to another entity
is another. As long as they keep it contained within their network,
it's pretty much up to them to break their own environment however
they see fit, but, if they start leaking 7.0.0.0/8 or subset announcements
on to the internet in general, I wouldn't want to be them or one of the
companies that was accepting their routes.

Don't get me wrong, IPv6 has a long way to go in terms of
availability, peering, and application support.  But make no mistake,
the tide is turning.  Rogers is doing what they have to do proactively
to stay ahead of the curve of complete exhaustion.

I don't think they have to hijack space from DoD. I think there are a
number of other options available to them. They might cost more, but,
they also come with somewhat lower risks.
