Same from LACNIC. This would have justify a /44 or separate /48s for each site. /as On 31 Oct 2011, at 12:45, Justin M. Streiner wrote: > On Mon, 31 Oct 2011, Owen DeLong wrote: > >> Ideally, you should put a /48 at each location. > > Speaking from my experience with getting v6 spac

My take on the issue is that your providers are wise in not wanting to accept prefixes longer than /48s. You should get multiple prefixes, from the same or different RIRs. If there are policies in place which do not allow you to do so, I think it's a good time to discuss them. regards Carlos On

Thanks to everybody who responded. To summarize it all, these are the guides for non-ISP company to use PI IPv6 addresses: case 1: single POP, no plans to have more - get single /48 from your RIR, announce it to one or multiple ISPs that POP is connected to case 1a: multiple separate POPs (no VP

Not sure about RIPE, but under ARIN, you would qualify for a /44 (or larger if you have more than 12 sites), out of which you could announce the /48s independently and as an aggregate, as you wish to do. -Randy - Original Message - > Hello, > > Please advice what is the best practic
