Hi, I have a question which was originally I was asked by my client. Our client has IP address space that was originally assigned from ARIN. Their address space is a big enough to separate to /20 each. I am not sure about internaltionl IP address assignment. 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. Is there any problems doing this? thanks, Kenji

As the IP addresses were obtained in some form from ARIN, I would suggest that your customer reads through the ARIN documentation associated with the assignment, and/or formally contacts ARIN. --==-- Bruce. Speaking for myself.
Hello Kenji, There is not a policy that states IP address space allocated by ARIN has to be utilized exclusively in the ARIN region. ARIN is not in a position to place limitations on how this IP address space is routed, but does encourage aggregation. If you would like to be certain there are no conflicts with the proposed use of this IP address space and the conditions under which it was allocated to this organization, I suggest you have them contact ARIN by either sending email to hostmaster@arin.net or calling the registration services help desk.

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. regards, Arnd -- NetHead Network Design and Security Arnd Vehling av@nethead.De Gummersbacherstr. 27 Phone: +49 221 8809210 DE-50679 Cologne Fax : +49 221 8809212
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 ... -Chris -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Arnd Vehling Sent: Thursday, March 22, 2001 3:05 AM To: Kenji Anzai Cc: nanog@merit.edu Subject: Re: using ARIN assigned address in Asia Hello, Kenji Anzai wrote:

I am unaware of ANY service provider who filters on /19s anymore, excepting old Class B space, which is usually filtered on /16s. Because the RIR's issue /20s, everyone accepts them. Your milage may vary, of course. - Daniel Golding

My mistake. However, the statements: We accept /20 and shorter in the 24/8, 61/8, 63/8, 64/8, 65/8, and 66/8 address space In the traditional Class C space (i.e., 192/3), we accept /24 and shorter. in Verio's routing policy, effectivly means that folks issues /20s by RIR's will have no problem routing them, which was actually my point. With RIR's issueing space in 0/1, most providers filter at /20 or /24 boundaries there. Obviously, a few providers like Verio are more granular.
