this depends on the end-user allocation size though, I make 20m
customers with /56's (which may be the 'right' answer for cable/dsl
users) 1.2 /32 equivalents, so call it a /28 if you like the nibble
boundary method.  Right?

it's 308ish /32 equivalents or a /20 (really a /23, but nibbled up to a /20)
