  Today's "Internet" is a superset of internet providers interconnected 
  using a common EGP routing protocol -- BGP4.  To participate in a 'NAP' 
  and exchange routes with volumous amounts of peers, BGP4 is pretty 
  much a necessity.  In most all cases, BGP4 requires that the person
  announcing routes use a unique ASN.

  If you want your upstream to provide the routing announcements for
  you, they can anounce your networks with their ASN.
