RE: using ARIN assigned address in Asia

OR ...

	You could always be sure and connect to the same "backbone" provider in
each location. then said provider can aggregate the two /20's to a /19. If
you need/want a second backbone provider in each location. get a connection
between the US and Asia locations. You could even do this as a tunnel using
just the port addresses of each connection. OF course a tunnel may not scale
very well and might not be "a good thing".  There are just so many ways to
make sure that  /19 is announced to the "filtering" majors ...

By using i.e. announcing ip-ranges < /19 you risk beeing filtered by one
of the major ISPs.

I wouldnt recommend splitting it up in 2 * /20.
