This is a whole lot of cc:s to people who aren't even part of this group/list. One wonders with this many cc:s, how many bcc:s there also were, and to whom.
There are several thousand people on the NANOG list, and public web archives. I don't think this is a useful question. FWIW, I also don't think that repurposing 240/4 is a good idea. To be useful it would require that every host on the Internet update its network stack, which would take on the order of a decade, to free up some space that would likely be depleted in a year or two. It's basically the same amount of work as getting everything to work on IPv6. R's, John
