IPv6 is not here (yet). In fact, it is still very far

There is news that because the final IPv4 blocks have been allocated, that IPv6 is supposely “here” now. The news came from APNIC:

APNIC received the following IPv4 address blocks from IANA in February 2011 and will be making allocations from these ranges in the near future:
* 39/8
* 106/8

APNIC reiterates that IPv6 is the only means available for the sustained ongoing growth of the Internet, and urges all Members of the Internet industry to move quickly towards its deployment.

Yes, the final /8 blocks have been allocated. And I agree that with the limited number of IPv4’s, we will need to figure out something to do very soon (everyone migrate to IPv6, use more NAT, etc). However, that doesn’t mean that IPv6 is here already…

In fact, I checked the TOP 1 million sites from Alexa and only 1,981 of them have IPv6 enabled in their main domain. It means that only 0.19% of them have it already. Very far from mainstream usage.

From the top 10k domains, only 57 have IPv6 enabled (a mere 0.57% of sites):

We still have a lot to go until IPv6 is here … My biggest concern is not with the adoption itself, but with the very limited number of people that really understand IPv6 well to make the migration smoothly (ask around, who is familiar with it?).

It’s been almost 5 years since this post. From what Sucuri has told me, they are completing IPv6 roll-out soon. They have internal support, but not external (yet). So, if you have an IPv4 and IPv6 enabled site, you will end up with only an A (IPv4) firewall IP, *or* direct IPv6 traffic directly to the origin server, somewhat defeating the purpose of the firewall. I am hoping they do complete the roll-out soon, because this partial support is definitely insufficient. IPv6 is here. No more stop-gaps.

My overall experience with Sucuri has been positive so far. With any CMS you run the risk of a 0-day exploit hitting you. Using a firewall that is actively monitoring for these is the only effective way to mitigate this sort of attack, and Sucuri is affordable. They have some good post-hack recovery options too, though I’d hope to never have to use them.

I do especially like their WordPress plug-in that can send email alerts on literally every change. Put them in a special folder (filter them) and it creates a nice remote auditing log.
