IP address blocks for out-of-band inter-provider links
While working on how to set up an out-of-band communication network between several providers, a question about whose IP addresses to use came up. The intent is to provide an out-of-band management network allowing member providers to exchange management information and alerts even if the main Internet is severely congested by malicious traffic. Because this isn't supposed to be connected to the Internet, its not necessary to use IANA/ARIN/RIPE/APNIC assigned IP address blocks. Several providers use private addresses on their out-of-band management networks. I would prefer to use globally unique IP addresses between providers to avoid conflicts with the RFC1918 private addresses already in use in provider's networks, and if the addresses accidently leak. Other than exchange points, are there any other cases of unique IP addresses being allocated for multi-provider purposes?

But of course, all the people involved have their border routers configured to do proper egress filtering of 1918 addresses, so they won't leak very far ;) Having said that, you can probably make the case that you're building a "virtual" exchange point, and ask for some address space for that? -- Valdis Kletnieks Operating Systems Analyst Virginia Tech
Well, it sure looks like a "virtual" exchange to me.

Also looks like every private interconnect in the business-to-business world, where people have for years been asking for micro-allocations so that companies, who generally all use RFC 1918 addresses internally, can have SOME address space that's guaranteed uniquely numbered. I don't see a good reason why a confederation of ISPs/NSPs/etc. doing what is essentially a private, B2B network should be afforded any different treatment in this area than other businesses. Don't get me wrong, I think such allocations SHOULD be available from ARIN/RIPE/APNIC. I think it's a good thing that the networking community might finally understand why. ----------------------------------------------------------------- Daniel Senie dts@senie.com Amaranth Networks Inc. http://www.amaranth.com
