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 ...

Hello,

Our client has IP address space that was originally assigned from ARIN.
Their address space is a big enough to separate to /20 each.

They would like to use front half (/20) in North America.
And, they would like to use the other half of the address space (/20) in
Asia.

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.
