30M IPv6 addressing

Are VM experimenting with IPv6?

I seem to have an IPv6 address

Just because the hub is giving you a local IPv6 address or the NIC itself is converting it into a IPv6 it doesn't mean to say that they're using a WAN IPv6

Here's mine on a static local IPv4 address which the NIC is automatically allocating an IPv6 addy based on the IPv4 and MAC of the NIC

If I remember my stuff correctly fe80s are what are called "link local" addresses which are private addresses like APIPA (169.254.x.x). With ipv6 every device will have an fe80 address even if it has got a WAN address (global unicast). The nice about ipv6 is that each device can have mtultiple address such as the local address, wan address and also multicast addresses all at the same time.

As far as the op is concerned your ipv6 address isnt something Vm are doing, it is something the latest versions of windows are doing to give themselves an ipv6 address. Link local addresses are non-routable so if VM were to flick a switch and all of sudden get rid of your ipv4 address you wouldnt be able to get on the internet. Global unicast addresses start with 2000:

Guessing VM will do public trials with members before they give IPv6 in the SH firmware???

General Maximus · 05-08-2012, 19:41

just thinking about it now is making me laugh. I hope for the customers' sake that they do extensive trials with the shub firmware to make sure ipv6 works before they even think about general release

Thanks Guys, I didn't think it could be but I was confused as my 82........ip address didn't appear anywhere.

Kymmy · 06-08-2012, 10:15

I presume you were connected directly to a modem previously.. that is how you would have got an 82.x.x.x address..

Through the SH or via any other router you'll only get a local address (192.168.x.x or 10.x.x.x)

progers · 06-08-2012, 10:22

Thanks Kymmy, I'm new to SH, one week, but happy with it.

Graham M · 06-08-2012, 13:58

IPv4 devices can also have multiple addresses if required

if you have a look at the settings in the shub you'll see that it now has your 82.whatever ip address because the router part of the shub is now the thing which is connected to the internet and will have the outside ip address. If you imagine you have got 2 pcs in your house, 3 laptops, 4 mobile phones, a wireless printer and networked tv & dvd player, they all cant have the same ip address because the router wouldn't know where to send the traffic to. Soooo, the router does what it is called network address translation. Each the devices on the work will be given what is called a Class C private address (192.x.x.x) so the router knows who is who but when they all try to connect to the internet they share the same ip address. That is why the ip address of your pc is 192.168.0.100. Your default gateway is the router whose address is 192.168.0.1. I wont go into the ins and outs of how it does it but it knows that yours pc has sent a web page request off to www.amazon.co.uk so when the page content comes back to your ip address the router know to send it to the pc and not the printer.

192.x.x.x i.e 192.0.0.0/8 is not a 'Class C address' - Class C network addresses are 24 bit in the range 192.0.0.x (192.168.0.0/24) to 223.255.255.x (223.255.255.0/24) with an 8 bit host address 'x'.

I'm sure you just forgot...

General Maximus · 06-08-2012, 20:57

I didnt forget that, I chose not to go into that level of detail just as I chose not to explain NAT and PAT in great length because the op wouldn't understand and doesnt need to know. I actually appreciate you correcting me though because I do like to try and be as accurate as poss although it still would have opened a can of worms if I said 192.168.0.x for the shub and 192.168.100.x for most other routers. That is why I chose to use 192.x.x.x to keep it simple.

Confucious say "when in hole stop digging"...

I wonder if the OP finds it as patronising as I do that you believe he "wouldn't understand and doesn't need to know"?

If you wanted to keep it simple you wouldn't have used 'Class C' or mentioned "most other routers" at all, you would have simply said that the example devices would get an address above 192.168.0.1 from the SH. The OP shows a screengrab with a PC address of 192.168.0.100 so you didn't need to 'simplify' to 192.x.x.x - In fact you made it more complicated.

I'm amused however that you use 'most' as you usually do i.e 'in your experience' rather than the conventional meaning of 'majority', that is unless you can quote statistics for 'most routers' using 192.168.100.x'?

Still definitely OT now, and the OP has their answer - VM is not responsible for the IPv6 address shown

General Maximus · 06-08-2012, 21:29

I dont think the op finds it patronising at all and appreciates what I have explained to him. If he didnt understand the fact that the shub had given him a private address to use on the lan and it was the shub that had the routable wan address then I am not going to complicate things further. Yes I did provide unneccessary detail in the Class C bla bla bit but sometimes I can't help it when I am trying to explain things.

Well done though because once again you have managed to do what vmfriend did and completely side track from helpful and honest information/advice to pointless bickering. Maybe you should focus your efforts more on being the first person to respond to posts and then you can guarantee all the information provided meets your high standards and you won't have to pull apart everything I say.

Helooo

Looking this thread explaining about routers how working the address i have maybe an issue if some want to just tell me with out details ... can be fixed or not

My other ex providers routers was fine
Got a draytek 2920n and sometimes the mobiles,laptop,other pc even the main pc i am on now will appear in the 2920 data base with different addresses (example the mobile has 168.192.1.13 then when it go off internet then the laptop take this same address but this happens from time to time and not each time the device will go off line)

This cost as result some times the device to show limited connectivity (which maybe is a deeper story but lets leave it)
As said the previous provider routers was keeping always same address for each device not matter if had performed reboot reset change firmware of previous modem/routers

So with out details is this a fault/bug or normal for the router and is just me don't know to use the draytek (almost all settings are set by factory default) as it little over complicated for my little knowledge
Thanks
