If one wants to go back to the first formal attempt at a definition, the
NII defined an ISP as a seller of dedicated connectivity, which was
presumed to connect to one or more IXes for peering, and purchase transit
from one or more NSPs.  IAPs (Internet Access Providers) were assumed to
just retail dial-up, and be single-homed to an ISP.  NSPs were assumed to
be national or international in scale, wholesale only, and present at many
IXes.  It was assumed that all of these provided basic services like DNS,
mail servers, and news servers, but that the degree to which they focused
on application services like that would be higher, the lower they were in
the hierarchy.  Thus it would be a significant part of an IAP's service
package, and a very small part of an NSP's.

So yeah, that basically lines up with Kandra's definition.

Mm, me either, however Critical Path was one of the first big (if not
successful) ASPs, and email was the only thing they did.  So I guess one
has to differentiate between engineer's use of words and marketing-folk's
use of words.  :-)
