That was kind of my point. You are unlikely to encounter such a large L2 domain outside of an exchange point.
I've seen such large networks in private industry (and governements, not just the US) several times. And IPv6 has been designed (poorly, it would now appear) for huge "LAN"s -- LANs are supposed to be /64, after all. One of them "had" to have such stupid large L2 domains because they used RIP (v1) EVERYWHERE. (all networks had to be /22's) They made a god aweful mess trying to switch to OSPF, got fined by a three letter regulatory agency, and are probably still running RIPv1 to this day.
