metro2012 Posted July 20, 2012 Share Posted July 20, 2012 i have a ddwrt router and i would like to transition my network from ipv4 to ipv6. my isp provides ipv6 so thats a plus. the thing is i would also have to have a 6-to-4 tunnel as most sites (including neowin) are still on neowin. my checked all my network equipment and from the looks of it, they all support ipv6 :) so how can i see a guide to make the transition? thank u.

+BudMan MVC Posted July 20, 2012 MVC Share Posted July 20, 2012 Why do you think you need a 6to4? You want to go full iv6, without ipv4 on your network? Dude ipv6 is not going to be mainstream for 10+ years at very min. Hey more power to you to want to get ahead of the game, I dabble with ipv6 myself - but you are off your rocker to think you can go ipv6 only. If your isp provides you ipv6, great run it dual stack for say the next 5 years or so - then you can think about going native only. So here is a honest question for you, from our other thread you don't understand to be honest basic networking very well. Very week in routing to be sure -- and you think you should move your network to ipv6 only? Tell you what get it up dual stack, then you can think about going full native. And I would highly suggest you run through the certification at hurricane electric - FREE, hey you can get a t-shirt once you get to sage. Its about 2 hours tops worth of play time, answer some questions bring up a couple of different servers that are reachable on ipv6, etc.. http://ipv6.he.net/certification/cert-main.php Link to comment Share on other sites More sharing options...

+BudMan MVC Posted July 20, 2012 MVC Share Posted July 20, 2012 You setup your router for it. This hands your internal boxes their ipv6 from the /64 your isp will give you. Then you have both ipv4 and ipv6 address on them. For example my box C:\Windows\system32>ping ipv6.google.com Pinging ipv6.l.google.com [2607:f8b0:4009:801::1014] with 32 bytes of data: Reply from 2607:f8b0:4009:801::1014: time=37ms Reply from 2607:f8b0:4009:801::1014: time=35ms Reply from 2607:f8b0:4009:801::1014: time=34ms Reply from 2607:f8b0:4009:801::1014: time=35ms Ping statistics for 2607:f8b0:4009:801::1014: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 34ms, Maximum = 37ms, Average = 35ms No you don't need a tunnel?, and 6to4 is not really a tunnel, is how you get to ipv4 when you only have ipv6. Thats going to be way way way down the road to be honest - http://www.ietf.org/rfc/rfc3056.txt I have ipv6 turned on for a few of my boxes to PLAY with, since that is what it is currently - play time. I work in IT, my current company supports some major companies, and not 1 of our customers is thinking about ipv6 deployment. Sad really, I have asked around the global company mind you and I can not find any of even international supported customers that are doing ipv6, even in a dual stack setup. Not saying nobody is doing it, just that its not very common - its not going to be main stream for years and years and years. I will most likely be retired before its even got a real foothold.

+BudMan MVC Posted July 20, 2012 MVC Share Posted July 20, 2012 ^ exactly, there are not very many isp that are doing ipv6. You can always grab a tunnel - grab one from HE, they are FREE an you can even get a /48 if you so desire. My isp (comcast) is suppose to be doing ipv6 - and lots of people have it in NA, but I have yet to get my native working. I can get an IP, I can get my /64, etc.. but seems in my area something wrong with the RAs - I am not seeing any! I have multiple posts out on the different support forums for comcast. And have not gotten any actual useful response. Done my sniffing, your NOT sending out RA (router advertisements) -- so kind of hard for it to work ;) So for now I still use my very stable easy to setup tunnel from HE.. lots of information on how to set that up with dd-wrt, I use pfsense as my router - and the ipv6 feature set it sweet as hell. Currently running 2.1 beta which makes working ipv6 a breeze for your network. Link to comment Share on other sites More sharing options...

No decently priced router had the oomph to get full speed out of our connection so we used pfsense. I would love to use it at home but the electricity usage for me would be too much.

+BudMan MVC Posted July 20, 2012 MVC Share Posted July 20, 2012 "but the electricity usage for me would be too much. " Ya don't need to run in on a server class dual power supply enterprise box. I run my in a VM on esxi, looking at the killawatt my n40l box it connected too. The whole box is drawing like 55 watts. So its been on for 2429 hours and has used a total of 135KWH, so lets see I pay about 0.125 per KWH -- so your talking $16.875 for 2,429 hours or 101.2 days so to run my whole ESXI box, that runs multiple VMS, has 4 drives currently - so your talking $16.875/101.2 days or less than 17 cents a DAY. Now I didn't win the lottery or anything - but hmmmmm, 17 cents a day to run my Router, my NAS, my linux box, etc.. Think I can swing that ;) What do you want to put it on that you feel it would suck too much elec?? Maybe you should recheck your math ;) How much elec do you think your desktop PC uses - do you have a ups that reports watts? I have my desktop, monitor and modem plugged into mine and its currently drawing a whole 73 watts - if I turn off the monitor its like 43-48, so you might want to rethink how much it cost to run a computer 24/7/365 even a full blow desktop model that would be WAY MORE than you need to run pfsense.

+BudMan MVC Posted July 23, 2012 MVC Share Posted July 23, 2012 Where did I say that?? You seem to have clearly stated that your ISP is not doing ipv6 yet "Some ISPS like mine (cablevision) do not even hand out ipv6 ip's yet." If you isp is not doing native ipv6 yet, then your only solution if you want to run ipv6 on your network is a tunnel. dd-wrt can be setup with hurricane electric tunnels very easy. edit: My bad, that was a different poster. If your isp does do IPv6 then you will have to check with them how to set it up. Or you can go with tunnel option if they are not quite ready for prime time. Some are only handing out 1 ipv6 address for users that have 1 device connected to the modem. And are not yet handing out /64 for router users.

Here read this for some examples of how big the address space is http://www.tcpipguid...ressSpace-2.htm The earth is about 4.5 billion years old. If we had been assigning IPv6 addresses at a rate of 1 billion per second since the earth was formed, we would have by now used up less than one trillionth of the address space. The earth's surface area is about 510 trillion square meters. If a typical computer has a footprint of about a tenth of a square meter, we would have to stack computers 10 billion high blanketing the entire surface of the earth to use up that same trillionth of the address space. Here are a couple more analogies of the size difference in ipv4 vs ipv6 So, ball park, if all the IPv4 space would fit in an iPod, then all the IPv6 space is the size of the entire Earth.

(ill use ipv4 addressing so i dont have to write aa:22:bb etc etc....) if my ISP assigns me 198.234.111.234/255.255.255.0 i could use, 198.234.111.999, 198.234.111.1000,198.234.111.1001,198.234.111.1002, etc, for all my PCs in my network? (i want to say again that yes i know that the max number is 255 in ipv4, but i wanted to put a example that shows the posibility and what you are telling me about ipv6). once i get the details from my isp, how do i set it up to work in dual stack mode in ddwrt?

+BudMan MVC Posted July 24, 2012 MVC Share Posted July 24, 2012 " how do i set it up to work in dual stack mode in ddwrt? " And how is your isp rolling out ipv6, maybe they are currently not even supporting a dual stack/native method? Maybe they are using 6rd? You are going to need to contact your isp on how they are rolling out ivp6. I would assume dhcpv6-pd, but you never know - problem is I don't believe dd-wrt currently support it. You would have to move to openwrt for dhcpv6-pd support, etc. Link to comment Share on other sites More sharing options...
Roger H. Veteran Posted July 24, 2012 Veteran Share Posted July 24, 2012 Tomato Toastman builds supported DHCPv6-PD also (well in that i see it as an option, no native IPv6 here - Cablevision). Here's what an IPv6 address looks like and the way the router is shown as well: (Took those from Broadband Reports forums). Anyways, your router would be assigned a block of addresses, as was said a /64 which is more addresses than the ENTIRE IPv4 network currently can carry. So then you can put 4 BILLION devices and more on your network if you so want to. LOL. So from the screenshot, Comcast assigned 2601:000c:1b80:/64 to that user so then they can use any combination of that after for other devices on the network. The Fe80:/8 addresses are similar to the 192.168.x address we have now. Those are all internal/local. Link to comment Share on other sites More sharing options...
