Subject: Classful Boundaries.
OK you big heads. Someone explain this to me.
Does the term "classful boundary" currently refer to:
A: The range into which a given addr falls that differentiates it from one
that falls into another, ie:
This network, 10.10.10.248/29 is a Class A subnet.
(since 10.x.y.z falls under the pre CIDR class A)
OR
B: The bit boundary closest to the bitmask in eight bit increments, ie:
This network, 10.10.10.248/29 is a Class C subnet.
(since the closest bit boundary is /24)
You will be settling a bet, so DON'T gimme that "both answers are right" or
"it depends on the context" or "just let the cat go unharmed and we'll sort
all this out without police involvement" stuff.
Which interpretation is more relevent?
