There are unallocated /8's that are privately routed. A lot are controlled by the U.S. DoD. But every time they come up, the response is always "so what? use IPv6!"
I generally agree. Putting those in circulation would actually be a bad thing. It would allow IPv4 to continue to zombie-walk for another couple years, maybe another decade, and in so doing to become more deeply entrenched, harming us in the long-run. IPv4 is technical debt.
It's also important to consider why DoD (and some large corps too) likes to sit on these address spaces. The problem with IPv4 isn't just that there isn't a big enough address space for every device on the Internet. IPv4 also lacks enough address space to permit the easy allocation of non-conflicting private address spaces. Ask any large-scale enterprise network engineer what happens when two companies merge or want to interconnect corporate networks and both use 10.0.0.0/16 as their address space. The answer is a visit to the bottom-most circles of NAT hell where sinners are boiled in firewall port remapping rules for all eternity. Either that or one of the merging/linking entities must renumber their entire network, which is often even more painful.
It really, really pains me that so many cloud providers are taking so damn long to support IPv6. Does Amazon even support it yet? I heard Digital Ocean was finally doing a limited beta. Jeez.
- joshavant 12y agoIPv6 is native and default at Linode.
- chrisseaton 12y agoBut for some reason they don't set the AAA record for the default subdomain they give each instance, or they didn't last time I tried.
- btgeekboy 12y agoThe cloud provider problem is definitely real. I have an idea for a service that requires both IPv4 and IPv6, but Linode and Rackspace were the two I found that both support native IPv6. Otherwise, it's something involving a HE.net tunnel, which I'm not comfortable with for more than experimental use.
- deathanatos 12y agoA note on Rackspace: we see about 2–3% of the VMs we allocate come with only an IPv4 address. We have no idea why — we suspect it's a bug on Rackspace's side (we allocate everything automatically, through the same code path, so it isn't us!). We currently only use the IPv4 address (I know, I know!), but it does present a bit of a problem when/if we decide to move.
- oasisbob 12y agoRackspace also doesn't support IPv6 if you use RackConnect, which is a bummer.
- thedude75 12y agoHi there! I work at Rackspace and I'd love to get our product engineers involved and review this issue for you. Would it be possible for you to email your account number and any pertinent server information (hostname/IP address/etc) to help@rackspace.com so that we can investigate? Thanks!

- teepo 12y agoSoftLayer has supported IPv6 for years. All their servers have IPv6 enabled.
- btgeekboy 12y agoThanks for the info. I'd not remembered them in my search.
- chimeracoder 12y ago> It really, really pains me that so many cloud providers are taking so damn long to support IPv6. Does Amazon even support it yet? I don't work at Amazon, but I spoke with someone about this recently, and I believe the issue is that Amazon provides virtual hardware and a virtual networking stack, and the tooling required to virtualize the networking stack in IPv6 isn't mature enough yet. For providers that offer dedicated hardware, this isn't an issue, but Amazon's services abstract over a very complicated and intertwined stack, so I can understand why it would take them longer.
- _asciiker_ 12y agoKimeraLive.com supports IPv6 since 2012, we have more than a few private data-base servers that have IPv6 only access. Cloud providers are not the problem, Internet Service Providers are, at home I'm stuck with IPv4 still.
- nly 12y ago> It really, really pains me that so many cloud providers are taking so damn long to support IPv6. Not sure about cloud providers, but several VPS companies already offer discounts for you to go IPv6 only.
