My ISP activates ipv6, what to do?
-
Hi,
My ISP provider send me an e-mail that they are going to activate ipv6.
I have set their modem in bridge mode and run pfSense on a mini-pc as main router/firewall. However ipv6 is not yet actived in my configuration.Is there a manual how to activate ipv6 if pfSense is already configured without ipv6?
If so, do I need to turn on "Prefix Delegation"? (point 3 of ISP 's letter)Below is the letter I have received with the information:
*Dear Sir / Madam,
Is your modem at home in bridge mode? Then it is important to read this message carefully. We are going to activate IPv6 for you. Your modem in bridge mode gets IPv6 support to be prepared when the IPv4 addresses run out. With this, everyone with Ziggo Internet, regardless of how their modem is set up, will soon have access to IPv4 and IPv6. You are thus prepared for the future.
IPv6 in 2 weeks
In 2 weeks we will activate IPv6 for you. So make sure you do the following (just to be sure, take the manual of your own router with you):
-
Check in the settings of your router whether IPv6 is activated.
Is IPv6 disabled? Then nothing happens, and the internet continues to work as you are used to. Do you want to be prepared for the future and/or do you have devices that only support IPv6, then activate IPv6. -
Check your router's firewall settings.
With a firewall you prevent your devices from being directly accessible via the internet. Are your firewall settings incorrect? Then a malicious person may be able to access your IP camera or network drive via the internet. Therefore, also set the firewall properly. -
On some routers: turn on Prefix Delegation.
Sometimes you have to explicitly enable Prefix Delegation (PD) to get IPv6 addresses in the home network. You may be asked to enter the value of the PD Size. That value is /56. Check the manual of your router for this. Is it asked for the type of IPv6 internet connection? Then choose automatic or DHCPv6.
Is IPv6 now enabled and your firewall settings correct? When you have made the adjustments, reboot your router. IPv6 will be available in 2 weeks, when we have activated IPv6 on your Ziggo modem. Also reboot your Ziggo modem in 15 days. Then you are ready and safe.*

There are a few settings to check. On the WAN interface, set IPv6 configuration type to DHCP6. You'll also likely need to select these:
Use IPv4 connectivity as parent interface
Send IPv6 prefix hint
Do not allow PD/Address releaseSet DHCPv6 Prefix Delegation size to 56
On each LAN interface (you can have up to 256 of 'em):
Under Track IPv6 Interface, set IPv6 Interface to WAN
Choose a unique IPv6 Prefix ID in the range of 0 - ff. Typically you'd use 0 for your LANThis should get you going.
Prefix delegation is how your ISP provides the prefix to your LAN(s). With a /56 prefix from your ISP, you can have up to 256 local LAN interfaces. Each of those would have it's own /64 prefix, so would contain 18.4 billion, billion addresses. You will likely also have a WAN IPv6 address that has nothing to do with your /56 prefix. It also likely has nothing to do with routing, as link local addresses are normally used for that. It's just an address to identify the interface.

@gschmidt that is actually pretty nice of them to send out such info about PD size, etc.
Is there an ISP out there doing ipv6 where they don't think their users are too stupid to set it up on their own routers - wow, impressive ;)
-
Thanx, i'll keep it in mind.
I have simple setup with only one LAN interface.
Maybe i'll first wait until i have devices which need ipv6 or a lack of ipv4 addresses.Btw I also have the same mini pc as you ;-)

Yeah going to be waiting a LONG time my friend.. For sure will not be currently using the hardware you have now ;)
Its nice to see isps preparing and all - but until such time that major players start turning off their IPv4 access, unless you "need" access to some resource only on ipv6 (zero of those that I know) of other than maybe some darkweb or p0rn sort of sites ;)
Can you name 1 major sort of site that requires IPv6? There are some real major players that do not even support as of yet..
Never too early to start learning about it - but yeah if you have no "need" and do not have the time to learn it.. Sure just leave it off.. Not going to hurt anything, and you not using ipv6 sure is not going to slow down the glacier like adoption pace that is ipv6..

My ISP, Rogers, is pretty good in that respect. They'll even help put the modem into bridge mode. Prior to providing native IPv6, about 6 years ago, they even had info on setting up 6rd and 6to4 tunnels.

@gschmidt said in My ISP activates ipv6, what to do?:
Btw I also have the same mini pc as you ;-)
It works very well and provides great performance.
-
My ISP "Ziggo" also activates bridge mode on request.
No complains here...but the Cable TV part sucks, since they broadcast some 4k channels. -

True! I also run ACME and HAproxy...which works quite smooth on this hardware

A while ago, I mentioned China was moving to IPv6 and last week I was reading about India requiring ISPs to provide IPv6 alone or dual stack by Dec. 31, 2022. There are a lot of people here from both areas and they may find themselves needing IPv6 soon to reach sites over there. I would like to see more such mandates here and elsewhere. IPv4 hasn't been adequate since the day it became necessary to use NAT. So, the sooner everyone moves to IPv6, the better. I realized that when I first learned about TCP/IP and realized that 4B addresses wouldn't be nearly enough. That was almost 27 years ago and I learned about IPv6 a few months later and realized that was the way to go.

I switched to IPTV last year and find it works well, with some benefits over the old digital system. Does your ISP support IPTV?

27 years is a long time...and ipv6 still not integrated...Hopefully my brain (now 53) is still capable by the time I need to dig in to it ;-)

They are currently on docsis 3.1, but on a crossroad whether to switch to optical fiber or update to docsis 4.0
The latest STB they have now is hybrid, live channels via Cable, records or movies via internet.
But they also have an app special for Android/Google TV which is quite responsive, only not 4K resolution. -
27 years ago, IPv6 was just being developed and wasn't anywhere near ready. But I remember sitting in the class learning about IPv4 and thinking 4B addresses wasn't enough even when I first heard about it. A big part of the problem is inertia, where people would rather stick their head in the sand, rather than get off their butts and do something. I live in Canada and 2 of the major telecoms are Rogers (my ISP) and Bell Canada. Bell used to be a world leader in telecom, with things such as the world's first domestic telecommunications satellite and AG Bell did some of his first long distance tests here (over the telegraph lines of a predecessor of a company I used to work for), but lately they've become an also ran. As I mentioned above, Rogers has been providing native IPv6 for around 6 years and via tunnel before that. On the other hand, Bell does not provide IPv6 to their Internet customers and barely to their cell customers. IPv6 is mandatory for 4G and later. A while ago, while using my work cell phone, on Bell, I only got 1/10 at test-ipv6.com. I get 10/10 on my Rogers phone and Internet. Other major telecoms, and some minor, have moved to IPv6, but not Bell. This is really sad, because IPv4 is holding up progress in using the Internet. For example, there are not enough addresses just for the mobile devices, let alone everything else. As a result, we have hacks on hacks to get around the address shortage and some of those hacks break things. Years ago, NAT broke FTP, until passive mode became popular. These days, we have to worry about STUN servers for VoIP and games. Even something like VoLTE¹, which uses the same protocols as WiFi calling, has to place the IPSec encrypted packets in a UDP packet, just to get around NAT.
Bottom line, the sooner we can move to IPv6 drop IPv4, the better.
- Voice over LTE & WiFi calling use SIP in IPSec in UDP 4500.
NAT Transversal
- Voice over LTE & WiFi calling use SIP in IPSec in UDP 4500.

Agree - problem is, just not happening.. The carriers moved their mobile devices over to IPv6, this cleared up lots of IPv4 space to be honest. There is a very flourishing IPv4 gray market in selling IPv4 space, etc. There has been some activation of previous unused IPv4 space, etc.
We sold off a bunch of our IPv4 /16 space for quite a bit of money, etc. So its not like companies that want IPv4 can't get it.. We only have a /19 left.. As the price goes up, you will see more and more companies sell off their IPv4 to people willing to pay for it vs switching to IPv6 ;)
Users don't give two shits - they just want to be able to get to www.whatever.tld - they have no idea what an IP is most likely be it v4 or v6..
The transition to IPv6 has been going on now for what 10 some years since, if you just count from world IPv6 launch day.. But many many years before that its been a work in progress.
I don't see it really going mainstream for another 10 atleast... I am talking when a user can not get somewhere that is considered a major player on the internet unless they have IPv6.. Prob more like 20 year out to be honest..

Tell that to someone in India in just over a year from now. This is already happening in some parts of the world, which have moved to IPv6 because of the IPv4 shortage. The "I don't need it so I don't worry about it" attitude is part of what's holding things back. Same with that IPv4 gray market and hacks like NAT & STUN. It seems some people would rather create hacks than fix the root problem.
-
@jknott Your looking at the WRONG way.. I am not saying there are not parts of the world that can only get a IPv6 on their device.. My phone is that way.. But my phone can also go to both ipv6 and IPv4 address because the carrier handles that transition for me when I want to get to a IPv4 only address. Guess what those users on IPv6 only can still get to IPv4 address, if not they would be bitching and screaming.. And nobody would use them..
What I am saying is if I don't have an IPv6 - I cant go somewhere.. What service would I want to connect to that requires me to have an IPv6 address.. Name one service that I can not get too - that I would actually want to get to.. I am not talking some shit site in some 3rd world country that only has IPv6.. I am talking a major player on the internet that the globe wants to get too.. That requires the client to have an IPv6 address..
When that happens!! Then you will see a move to ipv6 in a drastic way.. Until then - its just not going to happen quickly, its going to be slow drawn out process that is years and years still.. When you see some major player actually turn off IPv4..

The other day, I was reading about a situation, where someone wanted to have 3 Xboxes running, but NAT was getting confused.Sticking with IPv4 forces people to use NAT, which breaks things, as in this example.

Dude I am not disagreeing with you that IPv6 is better, and yes get rid of nat.. What I am saying is its NOT a requirement now, and will NOT be for many many many years still.
If the game makers would actually get IPv6 as true option for games, without still requiring IPv4 and actually doing it correctly - then maybe you could get some console players to say hey ISP we need IPv6 and we need it now, etc.. Still not a requirement.. Until there is something that requires IPv6 that the vast majority of people on the planet "can not live without" IPv4 is not going anywhere..
Yeah sure those people in those 3rd world countries are so happy they can play games together with their multiple xboxes and ps5 they all have in the same household ;)

You may not need it now, but the more people procrastinate, the longer it will take to move to IPv6 and the world as a whole will suffer for it. The shortage of IPv4 addresses was obvious many years ago and even to me, when I was just learning about IPv4. I remember sitting in the class and thinking to myself that 4B addresses wasn't enough.
We need more mandates to provide IPv6, just as happened in India, China and elsewhere. The move to IPv6 is being driven by the 3rd world, when we should be leading, not following. In Canada, many companies are providing IPv6, but for some reason not Bell Canada, where even on their cell network, where IPv6 is mandatory for 4G, they do a poor job of it.
Curiously, Telus, which is Bell's partner (they even shared cell networks) in the western part of the country, was one of the first to provide IPv6, even before Rogers, which I'm on. All the Canadian cable companies I'm aware of provide IPv6, as do some of the resellers that use Bell's ADSL network or Rogers' cable.Sticking with IPv4 is crippling the Internet.
