I say option 1 ..... If you look at most classful protocols such as igrp
/ rip 1 ... They always take only the original as defined "Classfull"
network definition , which is defined by the first few bits , so when
ipv4 was being developed they had to be fair , and have a solution to
give the most efficient netblock to requesting orgs ... So I believe
everything is still off of that original classfull definition so this
reinforces option 1 which you stated it is a "Class A network , using X
number of subnet bits" I like this option also because it is less
confusing.... And preserves history.. Hope you win
