Why does this computer not show an IPV6 address in my gateway?

SkiRod

Does anybody know why, when I look at the list of connected devices in my gateway, my work computer doesn't show an IPV6 address? Every other device in there except the cable box has a MAC, IPV4, & IPV6, but not my work computer. It's just the MAC & IPV4. Is it the company's VPN in the computer or the security dongle maybe? (SecurID)

Thanks for the help!

@SkiRod, it may be possible that your company disabled the ipv6 protocol via group policy.

@Marc Thanks! Is there a particular reason they do that? What's the difference between the two (IPV4 & IPV6) anyway? I never actually understood that. In the gateway, with the connected devices, they'll show something like a local link IPV4 & IPV6 & a WAN IPV6. I know LAN & WAN are local and wide area network, but I always thought that when you go online, you get one IP address that identifies the computer and your location. Is there an easy way to understand how that works?

Thanks again!

There could be many... their network infrastructure might not support it, the firms systems monitoring software, device management software etc... you would be surprised even after all these years how little adoption their is to ipv6 overall.

This is about the non-technically technical explanation that I found:

The biggest "why" is because the world has ran out of IPV4 IP addresses.  IPV6 resolves that issue.  However, internal networks will still be setup on IPV4.
