ARIN down to 1.00 /8 – Akamai got 104.64.0.0/10 yesterday

I remember reading about full IPv4-space scans showing some fairly massive blocks that were allocated but unused. As I recall it was well over 10% of the overall space that could theoretically be reclaimed and redistributed with a hand-wave.<p>Anything that gets IPv6 adoption to mainstream is a Good Thing, but more likely we&#x27;ll just start seeing the $1&#x2F;mo&#x2F;IP become $2&#x2F;mo&#x2F;IP, and upward... The squeeze will just continue as people make more money off of it, and we&#x27;ll still need IPv4 addresses for compatibility with people running Windows XP in 2020.

I work for Akamai and it&#x27;s worth noting that we also do a ton of work around IPv6: <a href="http://www.akamai.com/ipv6" rel="nofollow">http:&#x2F;&#x2F;www.akamai.com&#x2F;ipv6</a>

A lot of websites could use ipv6 to connect to a proxy&#x2F;security provider such as cloudflare which would output the site to ipv4&#x2F;ipv6 end users with all the other bells and whistles that cloudflare offers.<p>The end user then doesnt even know or care that the website he&#x2F;she is using is ipv6<p>btw does cloudflare support ipv6 only domains?

Seems a little absurd that one company just got 1&#x2F;4th of all remaining ARIN ipv4 adresses when there is such an insane crunch looming, no matter how big and important they are.

Maybe they should have come up with a version of IPv6 that didn&#x27;t basically require both to exist forever.

This seems to be a problem that markets will solve pretty well: as the resource gets scarcer, the price will go up, meaning people will have an incentive to use it more efficiently (selling unused address space), and&#x2F;or look for alternatives (IPv6).

I am curious if this news affects how many HN readers which are involved into the product development are developing their products &#x2F; websites with IPv6 support ?<p>If maybe this helps folks managing news.ycombinator.com to click the button and dualstack their site ? (Being behind CloudFlare, it is really just a click away, I am told).

If the certificate authorities can reduce the price of a SAN cert (multi-domains on a single IP, not to be confused with SNI), I guess a vast number of IPv4 can be saved, e.g. we host quite a number of client sites and we need IPv4 for each site just for SSL.

Ipv6 is still a terrible solution for so many reasons. Running out of addresses wasn&#x27;t and and still actually isn&#x27;t a problem, so stop pretending like it is.<p>IETF should have taken a pave-the-cowpaths approach and cleaned up ipv4, not created a huge incompatible ipv6 mess.

Still no ipv6 address from my ISP at home :(
