This gets confusing for the new Top Level Domains

http://NA.NOG

http://NANOG.GURU

What happened to NEW.NOG ?

There are only 256 members of NANOG ?
http://www.nanog.org/membership_main.html#list

Could (Does) each member *manage* a /8 ?
http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.txt

Many /8s are not used and many others are wasted. Why is that ?
Are people really paid $400,000 per year to manage that list ?
