  • Sorry, but your reply suggests otherwise.

    I’m at work, I’m not going to go into a thesis on ip allocation.

    The RIRs (currently) never allocate a /64 nor a /58. /48 is their (currently) smallest allocation. For example, of the ~800,000 /32’s ARIN has, only ~47k are “fragmented” (smaller than /32) and <4,000 are /48s. If /32s were the average, we’d be fine, but in our infinite wisdom, we assign larger subnets (like Comcast’s 2601::/20 and 2603:2000::/20).

    Correct all noted here https://www.iana.org/numbers/allocations/arin/asn/

    Taking into account the RIPE allocations, noted above, the closer equivalent to /8 is the 1.048M /20s available. Yes, it’s more than the 8-bit class-A blocks, but does 1 million really sound like the scale you were talking about? “enough addresses in ipv6 to address every known atom on earth”

    If you’re going to go through and conflate 2^128 as being larger than the amount of atoms on earth to a prefixing assignment scheme I’m just going to assume this is a bad faith argument.

    Have a good one I’m not wasting more time on this. The best projections for “exhausting” our ipv6 allocations is around 10 million years from now. I think by then we can change the default cidr allocations.

    Its old sure but not worth arguing further.



  • I’m fully aware how rirs allocate ipv6. The smallest allocation is a /64, that’s 65535 /64’s. There are 2^32 /32’s available, and a /20 is the minimum allocatable now. These aren’t /8’s from IPv4, let’s look at it from a /56, there are 10^16 /56 networks, roughly 17 million times more network ranges than IPv4 addresses.

    /48s are basically pop level allocations, few end users will be getting them. In fact comcast which used to give me /48s is down to /60 now.

    I’ll repeat, we aren’t running out any time soon, even with default allocations in the /3 currently existing for ipv6.
