For many years, a large customer (telco/VOIP/ISP carrier that should have known better) of a former employer was using 11.0.0.0/8 as an extension of 10.0.0.0/8 and literally forced said employer to carry their routes to those prefixes in those tables (or lose an extremely lucrative contract). At the time, 11/8 was IANA resrved, and my point that it was likely to be allocated to an RIR and subsequently some real entitie(s) on the internet was utterly lost in the pursuit of the almighty dollar. I left that job for greener pastures before IANA allocated that prefix, but I’m sure there were some definite interesting results there when it happened.
