Virginmedia ip addresses

thor

I read somewhere that virginmedia assign the same ip address to more than one customer(i.e neighbours may have the same).
Is this true and does it have something to do with transparent proxies?

Cant be true, It would cause confliction on the entire network.

I suspect that it would come as quite some surprise to Virgin Media that they have managed to change the entire way that the internet works.
OR
Don't believe all you read...

Some ISP's in the US use NAT to make several customers use the same IP address, but I wasn't aware any UK ISPs were using it. Its the same thing your router does to share your 1 internet address with all the devices you have connected to it, but on a bigger scale. It doesn't change the way the internet works, but it does break some stuff that requires end to end connections if both sides have this done. What they should really do is start rolling out IPv6.

I think just about all the mobile broadband ISPs use it. Virgin Media don't but Virgin Mobile almost certainly do which is where the confusion arose.

VM do have a proxy you can use and to a website everything going through that would appear as the same IP although the protocol lets the site get the true IP should they want it.

Each customer would still have a unique private IP address, but they would share the same public IP address used by the NAT.

yep, same as businesses with internet access.
different internal network IP address and a single 'internet' IP address.


also the same as anybody using multiple machines at home on a broadband connection

This must have been what I had read somewhere. So the website would have to do a teeny bit of extra work to see the true ip via the proxy.
