IPv6 Allocations

Since there is a lot of conversation about IPv6 flying about, does
anyone have a document or link to a good high level allocation structure
for v6?

It seems there are 100 different ways to sub allocate the /32, and I am
trying to find a simple but scalable method... .

Thanks!

See RFC 3531 and here:

This discussion has been done a bunch of times.

Here is my scheme, which has been adopted (sometimes with small modifications) by quite a few providers I have spoken with.

Read the whole thread because there was a bit of confusion.

I'm sure I'm just dumb, but no matter what numbers I put into that
tool, it only spits out a series of /32s on the HTML output. That
doesn't seem terribly useful, as most of us aren't going to be allocating
multiple /32s, we'll be splitting up a single /32 into smaller bits.

The tool is aware of the prefix length you insert. So instead of /32, put /64 or /48 etc.

Ah!
So, the instructions are wrong; instead of saying
"1. Enter the start prefix (i.e. 2001:db8::/32)."
it should say
"1. Enter the start prefix (i.e. 2001:db8::/40)."
since the example is talking about allocating /40's for downstreams.

Thanks--now it works a bit more coherently. :slight_smile:
