Abstract
With the increased growth of the Internet, the number of customers
using BGP4 has grown significantly. RFC 1930 outlines a set of
guidelines for when one needs and should use an AS. However, the
customer and service provider (ISP) are left with a problem as a
result of this in that while there is no need for an allocated AS
under the guidelines, certain conditions make the use of BGP4 a very
pragmatic and perhaps only way to connect a customer homed to a
single ISP. This paper proposes a solution to this problem in line
with recommendations set forth in RFC 1930.
