2006-01 IPv6 PI implementation
Hello, can anyone explain me is there a restriction in policy for assigning /48 PI IPv6 to ISP which will use /64-/128 prefixes to connect broadband customers? -- Sergey

IPv6 PI is for *your* network. IPv6 PI space is not to be used for assigning prefixes to customers - and this is very clear from the policy documents. If you want to assign prefixes to customers, become a LIR and get a /32 IPv6 PA (or larger). (Yes, this is different from the way one could run an "ISP" in IPv4 land, assigning single IPv4 addresses to customers, and declaring those to be "ISP infrastructure" - this is permitted by the current IPv4 policy, but this loop hole does not make any sense in IPv6 where you are supposed to assign whole /64 or /56 networks to customers) Gert Doering -- APWG chair -- Total number of prefixes smaller than registry allocations: 144438 SpaceNet AG Vorstand: Sebastian v.

Minimum IPv6 allocation to ISPs is /32 which will allow you to assign /48 prefixes to broadband customers. This makes network design simple and you would be following the same mainstream IPv6 implementation rules as most other ISPs. This will make it much easier for you to get support from your vendors and advice from other ISPs who are deploying IPv6. It also prevents your competitors from telling your customers that your service is bad because you give customers a smaller block of addresses/subnets. Really, only mobile phones or other devices should get /128 prefixes. Anything that is a network with potentially two or more devices on it should get a /64. And a broadband customer is a "site" so they should get a whole /48 unless you are very big. Some very big ISPs are giving /56 to customers in their private homes and only give /48 to an office or some kind of business. --Michael Dillon
