This number excludes prefixes that are smaller than a /24 and those prefixes that have been reserved for IXP assignments or temporary assignments. It might also be slightly larger by then, due to addresses that are recovered in the meantime.

Thank you, Nikolas, for the figures.

So we're still talking about ~3.8k _new_ LIRs that end up with a /22 worth of addresses in /24s or /23s before 2019-02 would kick in and prolongate the infirmity of IPv4. 3.8k new LIRs that happily can consider starting a business based on IPv4, a legacy technology, and ignore the facts.

Let's put this into perspective: "I see 757979 IPv4 prefixes. This is 238 fewer prefixes than 6 hours ago and 1051 more than a week ago. 57.04% of prefixes are /24. There are 63602 unique originating ASNs. 47266 of these ASNs originate IPv4 only" (Source: https://twitter.com/bgp4_table/status/1097420515206152192)

With still about 75% ASNs being IPv4 only, there's definitively no point in prolonging the availability of fresh IPv4 space by reducing the hand-out rate. "IPv4 is over", I hear — so let's be brave and stick to that statement.
