What's wrong with it? IPv6 addresses are 128bit

 

IPv4 addresses are 32bit.

Well, that's what an IPv6 address looks like :P

 

What exactly did it supposedly look like before?

Well how have you sen it, because that is how it is and has always been expressed. What i want to know is why you have a temporary ipv6 address have you setup tunneling or something?

well its in internal ip. so it makes sense. 

run ipconfig you have one too.

It's in hexadecimal, each character represents a number from 0 to 15, which takes 4 bits. The address is split into 8 groups of 4 characters, which totals 8 x 4 x 4 = 128 bits (16 bits per group). If a group begins with one or more zeroes, they can be left out.

I know i have one, what i don't have even when i do tunneling is a temporary ipv6 address, it shows up as static. So if he or someone else could explain how he has a temporary one.....

I personally do not have a temporary IPv6 address, and just because you have one, doesn't mean everyone gets one, it depends on the operating system and other things: 

 

 

In IPv4 it is required for a Network Administrator to either assign a static IP address to every device on a network or use a protocol called DHCP to assign a unique one automatically. In IPv6 an industry standard called EUI-64 was created to make assigning an IP address via DHCP or statically completely optional by allowing the devices to automatically generate one themselves. This is done by taking the MAC address of the interface and then 'squeezing' FFFE in the middle to generate the unique IP address that can be used on the internet for online communication. Additional characters are inserted in the middle in order to expand the MAC address (48-bit) into a 64-bit address to be used. More information on EUI-64 can be found here - IPv6 interface identifiers: IPv6

 
Windows 7 and 8 do not follow this standard and instead use a temporary address that is randomly generated and changes frequently to prevent other online users from being able to track you via your MAC address which doesn't change. While this is great for client privacy it can cause issues when setting up servers or key devices therefore you may wish to disable it and use the EUI-64 standard. This is what I am going to show you how to do in this tutorial.
 

Temporary IPv6 addresses are a feature of some Windows operating systems, including many that are supported by Tableau Server version 8.1.

could be your isp. as well.

had it on 7 /8,1/and 10.

Your point being? You said that everyone has a temporary IPv6 address, i went on to say they don't and that it's dependent upon your operating system, applications and other factors.

I have been running ipconfig since i first learnt my first set of commands back in 1990 or there abouts and i have never seen a temporary ip address either for ipv6 or ipv4, you guys are on some bloody tunnel network and don't even know it or your ISP has and ipv6 service running. Have you ever tried asking your ISP about it?

The IPv6 addresses listed are both Unique Local Addresses. The fc00/7 address block is reserved for this purpose. Think of them as the IPv6 equivalent to the private address ranges in IPv4 and are meant to help with the transition to full IPv6 networks. These addresses are non-routable and will be translated by your router with some form of NAT for IPv6. The first address listed as "IPv6 Address" was created in part from IPv6 DHCP device (first 64 bits), such as a home router, with the rest being randomly generated by Windows. Temporary IPv6 addresses are a Windows feature implemented due to possible security issues Windows sees with IPv6. Due to IPv6 being able to have a unique global address assigned to every device in your network, Microsoft is concerned with your address being out on the internet and never changing, thus periodically your PC will receive a new "temporary" address which will be the one used when Windows trying to talk to IPv6 networks outside your local link. It is a feature that is not really needed, but it is there none the less.

 

The extra overhead created by requiring that address to go through a NAT device is really unnecessary and the Unique Local Addresses are very much in disfavor due to this. If your router receives a global unicast prefix from your ISP it will be best to set that as your IPv6 DHCP scope. You may also be able to dissable the IPv6 DHCP service as IPv6 is designed to be able to crate it's own unique addresses through router solicitation messages and EUI64. However if you are not comfortable with tweaking settings you can just leave things as they are.

 

TL;DR - Those addresses are perfectly normal, although technically frowned upon, IPv6 addresses that will be NAT'd by your router.
