>From the ARIN site....

"ARIN is a non-profit organization established for the purpose of
administration and registration of Internet Protocol (IP) numbers for the
following geographical areas:

                                   North America, 
                                   South America, 
                                   the Caribbean and 
                                   sub-Saharan Africa." 

While ARIN is not oblivious to operational aspects of routing, their charge
is not directly impacted by that sensitivity...
(again from the ARIN site)...
"ARIN is responsible for maintaining a public trust. Among its
responsibilities, ARIN promotes the conservation of IP address space,
maintains impartiality while determining the size of address blocks to be
allocated or assigned, and supports efforts to keep the global routing
tables to a manageable size to ensure routability of information over the
Internet. Continued operation of the Internet depends, in part, upon the
conservation and efficient use of IP address space."

Subject: Question about 'portability'

 This is a fairly simple question, although no one I have approached seems
 to know the answer.

 Just because ARIN has deemed a network to be 'portable' does not give an
 end user any rights to the network, correct?  My thinking is that if ARIN
 has allocated address space to an ISP, and the ISP assigns/allocates a
 network further downstream, the end user to whom the network has been
 assigned has no inherent rights to the network just because its portable.
