I can think of other cases I'm not going to enumerate here, but

Actually, for the benefit of the use-cases draft, could you?

Take the end of EUNet as an example. There were some kind souls that kept the network up and running, and there were users behind the network. This space was routed by a variety of providers in the aftermath. The business risks would be higher today as a result (as a customer) and as someone trying to capture the business in the aftermath, there would be incredible pressure to get things done ASAP to bring a new customer online, possibly with their "old" space as the proper owner is not around to assert control/authority/objections.

typically transfers of customers and space take months if not years to sort out, while actual network control may happen more immediately. I

right, so "ownership" happens at a different time and space to network
origination? (That's been my experience, being in active takeovers of
companies where not upsetting the network and customers was the highest
priority - but still making sure the control was in hand)


This varies from company-to-company. I've seen it on the large telco scale and the small regional ISP scale over the years. Sometimes old staff is laid off as part of an asset acquisition, so it's hard to show proper authority for a period of time with your suppliers/vendors (SPs/RIR, etc)...

think we still have customers on "NTT" space that are homed on the
Cogent network from some prior transfers.


Can you elaborate in terms of ISP1 and ISP2 to protect the innocent?
Ie provide action timing? what happened when?

I think that real-life examples help explain the practicality of the process that ends up happening. We continue to forward security and abuse complaints as a part of the legacy. That happened in December 2004. Five years later there are still customers covered by this agreement.

Have to run for now, but this should help....
