I worked alongside a company that used addresses assigned to the Syrian govt for their "guest" network. They were a pretty large org, presumably this was done to reduce risk - firewall rules, accidentally leaking guest prefixes to their internal nets, or just straight-up simplicity. They were in a pretty heavily regulated industry with restrictions on what companies they could do business with, so there probably wasn't a huge risk of reachability issues.

I just heard of thishappening with a large ISP and never really thought about it until now. every time I seen a traceroute with 11/8 22/8 26/8 in it I am duly impressed.Robert
