The RIR’s assignment to ISPs assume relatively dense assignment of /48 to customers. ISPs still have to justify the allocation based on the number of customers sites for shorter than a /32. RIR assignments to non ISPs are also relatively dense. If you have multiple sites you don’t need contiguous addresses.
Automatic assignment in homenet does dense assignment. > On 21 Dec 2017, at 12:27 pm, William Herrin <b...@herrin.us> wrote: > > On Wed, Dec 20, 2017 at 4:57 PM, Mark Andrews <ma...@isc.org> wrote: > Handing out /48’s to homes was never ever going to cause us to run out of > IPv6 space.
