$250M for a /8 (2^24) is almost $15 per address, which is 35% higher than the recent public deal [1] (though in RIPE address space), so maybe the time of $16 per IP did not come yet ;-). I guess you've seen that at least in RIPE the transfers are alive and well: https://labs.ripe.net/Members/wilhelm/ipv4-transfers-in-the-ripe-ncc-service-region https://labs.ripe.net/Members/wilhelm/ipv4-transfers-in-the-... And ARIN just the other day put up for discussion the simplifications in transfer [2], so with the impending scraping the bottom of the barrel (today morning only /23s and /24s left, in total less than 200000 addresses) it should liven up. OTOH the higher the price per Legacy IP goes, the more incentive folks have to do IPv6. There's a odd satisfaction in having the lots "I told you so" moments in the past half a year or so, although I feel sad for folks who made the life for themselves more difficult than it should've been by pretending the IPv6 not to be a thing. Especially for the folks on HN doing startups: whereas before you could have gotten away with temporarily glitches in IPv6 connectivity when it was available with 2% users, today when you enable IPv6, 1 out of 5 users in the US will use it [3] - and predominantly mobile [4] - the US is leading. Not much time for learning on the job now! Luckily Cloudflare [5] and Akamai offer at least a temporary patch by frontending the site with IPv6 and providing the X-Forwarded-For. Later on, the use of CGN on IPv4 and NAT64 to reach the legacy IP sites will increase - now think of all these precious analytics they are missing because of CGNs hiding the individual users... Anyway a /8 could become more valuable when the IPv4 routing table grows bad enough that the operators start to filter the routes more aggressively. This is the fun part in the whole game to catch the moment to cash out. Sorry, this turned out to be quite a bit longer and more offtopic than I wanted, but hopefully might help some.
