Re: [uknof] UK IPv6 Taskforce
Now, only one of these groups is really feeling the pain of address depletion, and that's the access ISPs(2). Some feel that pain badly, and it's certainly true that there's no way you could enter the market as an access ISP in the UK given a /22 of address space. You can if you're selling access to your own services and you're dual stack. This allows you to run the CPE side in IPv6 only, but then you're possibly a content provider selling access to your own content?? :-) -- Kind Regards, Gavin Henry. http://www.surevoip.co.uk OpenPGP (GPG/PGP) Public Key: 0x8CFBA8E6 - Import from hkp://subkeys.pgp.net or http://www.suretecgroup.com/0x8CFBA8E6.gpg

Re: [uknof] UK IPv6 Taskforce
Neil I think Andy sums this up well. Also there has been some confusion about the taskforce. The taskforce didn't set up to tell ISPs what to do - in fact BT was prominently a founder back in 2001 but went cool when 21C Network became the foo of choice. My perspective was and remains as a developer and user of networks. I prefer to have networks that I can directly address devices over rather than being mediated. That is my main problem with the UK model for consumer broadband. It has ignored this basic characteristic. A somewhat broader point than IPv6 or IPv4 through address translators. I was sorry to see 6UK close but I completely understand the frustrations that led to it. Incidentally the taskforce never became a formal entity so there was nothing really to close down - but to answer Martin's complaint - the website had been moved from BT to U o Southampton when BT became less keen. But we downed tools to keep the space clear for 6UK when that was started. The TF participants were partly instrumental in pushing HMG to get that started. On that note I hope ISPs and operators as well as vendors will support the announcement of the new Council in Belfast so UK developers and users can start very shortly to assume everything will be addressable directly over v6 ASAP! best Christian Andy Davidson wrote: On 4 Sep 2014, at 23:03, Neil J.

Re: [uknof] UK IPv6 Taskforce
I respect those points and it is good that BT is again more proactive on this issue. Also I thought Brandon's comments on the complexities of deploying v6 within an applications service like the BBC offer some valuable clue that a user actually receiving IPv6 from an ISP is a small first step to achieving IPv6 support in the depths of v4 coded application services. First though such users will want to know v6 is widely available I expect. best Christian Neil J.

[uknof] Loopholes, Ethics and Business Acumen with Ofcom and RIPE
Hi all, Thinking about this, as I know it's being done but wanted others opinions on it and wondered what RIPE and Ofcom are doing about it or if they care: 1. RIPE - start a new Ltd company, pay your 2000 Euros to RIPE and get a /22 with no ASN. Transfer that back to your existing company for free. Saves paying £10~ per IPv4 address for a /22 on the open market. Or do this and add to your IP brokerage company so you can sell them. Various issues but folks are doing it. 2. Ofcom - with the newish charges per number range per year, for area codes that are classified as scarce, at £0.50 you get a £0.20~ discount on numbers ported out to another company. Upon a customer sign up for a telephone number in a scarce area, immediately port it to another Ltd company you own and receive your £0.20 per number per year discount. Thoughts? For me it's one of those things that should be very easily spotted and stopped, but does the blame lay with the schemes in general?

Re: [uknof] UK IPv6 Taskforce
Not true, there's plenty of things that content providers may care about that'll be broken under NAT44 and can be resolved by adopting IPv6. The obvious things being: Port forwarding Dodgy or non-existing ALG in the gateway, breaking things like SIP, FTP etc. Geolocation tracking and/or CDN steering. Access restrictions (Betting sites blocking multiple users behind one IP). These are just some of the issues we have to face with deploying NAT44, and yes they do have work arounds that work with varying success, but ultimately IPv6 uptake helps mitigate these issues for both the eyeballs and content providers.

I¹m not intimately familiar with Comcast¹s platform but at least its DOCSIS, doesn¹t do wholesale as far as I know, those would be pretty decent sized differences also but the key driver for IPV6 is not having enough IPV4 addresses, and at least in Europe that doesn¹t seem to be the case (yet).

Re: [uknof] UK IPv6 Taskforce
Scott, This has nothing to do with innovation - configuration maybe. If we had been innovative then we might not had needed V6 at all. For clarity though we have had IPV6 available on BT Internet Connect (business Internet service) for years- take up and demand very low. Traffic volumes don't even register on our graphs. I refer back to UKNOF where the 4 major service providers gave their views - remarkably consistent as I recall and I think it's recorded.

Re: [uknof] UK IPv6 Taskforce
Just to dive in on this debate. We have gone really hard at our customer V6 rollout because we believe it's the right thing to do and at our scale it's much more feasible. However I can tell you from experience that once you run with v6 live with real customers for a while there are many small issues that come to the surface, things we have found include: 1) The 'commodity' CPEs (in our case Zyxel and Netgear), have slightly flakey v6 implementations that are far from auto configuring and break occasionally in random and unpredictable ways. The Netgears are particularly horrible as they don't dual stack and require two PPPOE sessions. All of them have really basic v6 with all or nothing firewalls, etc. It's all pretty immature and lacks the polish of a battle tested solution. I am sure someone will suggest a 'good' commodity v6 CPE, but as we have our VDSL2 network things like chipset compatibility have to outrank v6. 2) Random sites and services not working on v6. Recently a customer called to complain MS Skydrive wasn't working for them, the answer was to turn off v6 on that customers CPE, and it's just not worth the time to investigate why and fix for v6. 3) Even on our side of the fence we encounter problems with what should be a robust solution by now, for example we use 7200s for our BNGs and implement basic traffic policing on PPPOE sessions, works fine on v4 traffic it works fine on v6 it either works in one direction or not at all. All of the above are trivial issues and with a bit of spit and polish by the vendors could be sorted pretty quickly, but they won't sort these issues until take up is at such a level it's a problem. We need that 'killer app' to truly drive demand from end customers and then it will all come together I am sure. Regards... Ben Sent from my iPhone On 5 Sep 2014, at 16:33, Neil J.

I am sure we can all come up with anecdotes, like your printer or the website with a in the DNS but a webserver that's not listening on that address.

Re: [uknof] UK IPv6 Taskforce
Will, If anyone has done V6 because of a business case then the hurdles they have must be insane! IPV6 is about being in this business. You mistakenly assume that in the UK we have done nothing which is massively incorrect - and my experiences about brokenness aren't just my own and speaking to many of the companies you mention it hasn't been painless for them nobody should be kidding themselves on that it was. The market in the UK I would argue is unique. Don't know if you remember the question I asked John from Comcast about the price of broadband in the US at the last UKNOF?
