4510L & IPv6

[John_Getzke]

Chris,

I have had the opposite experience with this device.  I was able to pull a local IPv6 address on my MiFi 4510L.  However, I have never been able to successfully detect and use a public IPv6 address.  The same was true for the newer MiFi 4620L.

Public IP Address check:

That being said I have not checked up on this issue in a while.  Perhaps something has changed that I am not aware of.

How were you able to get a local ipv6? Is there something about this in the config file for the MiFi?

[John_Getzke]

You need to have your OS configured correctly to recieve and accept IPv6 addresses.  Once you complete the steps the MiFi will provide a local IPv6 address the next time you connect.  I'll share some screenshots if I can find the time to get everything set back up again.

There are many tricks and techniques but I prefer the MS Fixit utilities for quickly enabling/disabling IPv6 on my Win7 laptop:

Here is the screenshot of a local IPv6 address from the MiFi 4510L:

But as you can see my Public IP Address still remains IPv4:

The fe80:: address is a link-local address. It did not come from your mifi. It's automatically supplied by the interface itself due to the fact that your operating system is IPv6-aware.

Thanks for clearing that up Nsayer. I supposed I never cared to look into it before and assumed it was working.

Now that you brought this to my attention I can see that the IPv6 address that I pulled is essentially the same as a 169.254.x.x IPv4 address.  Fe80:: is not routable and not useful for anything other than maintaining the standards of the protocol.  What a bummer, I had thought my local traffic was working over IPv6 this entire time : (
