How's that been workin' out for everyone?
If you'll all indulge a bit of a RIPE-centric reply on this; I've was
allocated a /22 from around half-way through 185.169.0.0/16 last week
(185 being RIPE's final /8).
Assuming that RIPE are allocating sequentially - and I believe they are
- This means that they have consumed around 66.5% of their final /8.
They started allocating from this in September 2012, which suggests a
reasonably low consumption rate but the RIPE final /8 will be exhausted
in around two years time.
I can't find an equivalent ARIN page of "how much we've allocated from
our last /8" - the statistics show that just over 2x /16s worth have
been assigned/allocated between January 2016 and July 2016, so a lower
rate by some margin than RIPE - but there are of course policy
differences at play there.
Now the operational question of "How has this affected us" is probably
best answered with "We've had to pay real money for IPv4 addresses since
then." What may be much more interesting is what happens when the
fairly ready supply of IPv4 addresses in the secondary transfer market
starts to dry up. Just throwing additional money at the problem will
probably not be an effective or viable solution then.
I'm sure that Geoff Huston has a much more accurate and colourful set of
predictions than my back-of-envelope calculations for those interested!
