I connected as usual with my portable usb device and got online on the internet but then I checked the IP address and it wasnt the usual formation ( xxx.xxx.xxx.xxx) now it was something like 2000: and then alot of numerals and alphabetics. From my quick google search I guess this is a called a ipv4 address.

Why did I see this strange IP address instead of the usual? Is there a virus? Is it legit that the ipv4 could be used as an external ip adress on the internet?

You mean something like this: 2001:db8:85a3:0:0:8a2e:370:7334?
That's IPv6 addressing.

The first 16 bits of the prefix are always 2002:,

I can add that when signing up you get a new ip number every time (its a mobile internet device). Really want to get to bottom with this.

Enter your IP here and it should point at your ISP.

Hi Phelp,

IPv6 is a new version of Ip protocol because Ipv4 is running out of IP addresses. Ipv6 is a extension of Ipv4. (basic level)

A ISP can issued what is known as a Public External Address

If I have a device call Mobile 1 that device connects to a external IP address

if I have 192.168.1.4 needed to covert that IPv6 it would be fe80:0:0:0:0:0:c0a8:104 (converted into hexadecimal)

your modem supported IPv6 that why you received a IPv6 address
