Peter and all, Yep this is and will be a problem. So than they need to apply for additional private space again and hope it hasn't been put in other routing tables, or seek a different solution. FWIW, I can acquire plenty of IPv8 private space that I am very sure isn't in anyones public routing tables. Of course the price is VERY reasonable as well! >:) Routes great on any VPN as well... And amazingly enough those businesses won't have any ICANN, ASO, Ripe, ARIN, APNIC, of AFNIC worries to boot. >:) Additionally, encaptulates IPv4 public IP's and IPv6 IP's seamlessly. >:) With the passing of FISA, I'm getting quite a few new discrete inquiries... So all is not lost, just changing... Ya just can't stop progress, slow it down maybe, but never stop it... Peter Galbavy wrote:

Fortunately there are no secrets in the routing table! So, it is easy to see if any given space is being routed or not.
The only time there is a problem is if revoked space is still being routed by someone.
Some address space owners rely the uniqueness property. This applies to 3/8 and 9/8, for example, but I'm sure that it happens on a smaller scale, too.
And, more importantly, PI space that is not publicly routed but must be unique. On behalf of clients in the past I have applied for and had assigned PI space for intra-organisational and/or VPN space. These large, sometimes multinational, companies have public connectivity and use private address space internally and where they need a VPN or secure connection between themselves they do not want that in the public routing tables but cannot use private space.
If this space is reclaimed on the simplistic basis of "it wasn't in the public routing table yesterday (or ever)" then reassigned, suddenly the original assignee finds their private and confidetial traffic might start leaking out one of their public connections. Great.
Peter
