There’s no place like ::1

With the move of house, comes a lot of other movements of technology. At the old place, I was on Virgin Media’s Broadband, Although I did not have any problems with them, I do know people that had more than their fair share. I think in the course of 2 years my line went down for a total of 2 minutes, and I think that’s fairly acceptable. However, it lacks on some features. Dynamic IPv4 address (and only 1) means I had to write some rather complex scripts, due to my server blocking SSH access from anywhere unless it’s a “Known Location”. These locations normally consist of my place of work, my place of home, and my parents houses for when I visit them.

Although IPv4 is being exhausted, many people are still using it, in fact, pretty much everyone on the Internet is using IPv4 in one way or another. For me, my new connection has a /28 mask of address’s, call me selfish, but this does give all my machines external IP’s, and then I’m NAT-ing Wifi connections, because they don’t need external address’s. It also has Native IPv6 on the new line. there is still very much a case of “No one’s using IPv6 so we don’t support it” and also “many things still don’t support it, so I don’t have IPv6″. In my 2 years working at Dyalog, I have moved our internal systems to IPv6, and so far 50% of our servers are on IPv6. The interpreter received it’s required changes to support IPv6 in version 12, and some of these will be improved in 12.1, and this improvement will most likely be on-going.

So, to IPv6, and who supports it? well, Google have had IPv6 work going on for a long time now, and you have been able to access http://ipv6.google.com to run your web searches. however they only resolve www.google.com as an IPv6 address if your ISP has registered with them. I can understand this to some extent, but on the other hand, it might hold things back, as there’s alot of people beating their ISP’s to IPv6 with Tunneling over IPv4. Google here have proved that a move to IPv6 can be done without too much effort, providing you can release resources into the change, and you have a good firewall, Remember NAT is not a firewall.

What about ISP’s, what are they doing about IPv6? well Andrews and Arnold seem to be among the few ISP’s offering native IPv6 in the UK, I believe there is currently no more than 3 ISP’s offering such service. Why? maybe they don’t see the point because not many sites are using it yet. Well, here’s some news, every site I run, has IPv6, that is my personal sites and company sites, Google also have IPv6. so what are we waiting for?

Consumer devices is where my attention is grabbed, Can you name a single off-the-shelf Consumer grade router / modem that supports IPv6? I can not. and I can’t see someone at home spending thousands on Cisco gear to have IPv6. My solution to this was to buy a consumer-grade Asus WL-500gp router, and flash it’s firmware with Linux. This now gives me IPv6, along with IP4 and IP6 firewalls that I am personally comfortable with configuring.

Maybe the big problem here with ISP’s supporting IPv6 is that the consumer devices do not yet support such a thing, this means it is completely pointless having the ISP’s support it. IPv6 is moving forwards, and in the last year or 2 there has been some very big movements. unfortunately, these movements are no going fast enough, and until consumer devices support IPv6 this movement will be on a slow trickle. we only need one or two big ISP’s to start supporting IPv6 in the UK for it to take off like a rocket over here, so maybe this is a cry to the manufacturers of the consumer devices to support IPv6 so the ISP’s can also support it.

Get on the IPv6 bandwagon, this is a vote for IPv6 move forward.
