Determine IPv6 for a connected device

Greetings,

I'm installing a new Ethernet device (it's a printer) and I made a slight oopsie.

 

I disabled IPv4 in the web admin panel, because my network is 100% IPv6. Unfortunately I was connected via IPv4 to the web admin panel!

 

Now I'm trying to determine the device's IPv6 assigned address(es) which should be at least one link-local and at least one routable: Surely the Nighthawk admin panels know this.

 

I have access control enabled and I made sure to unblock/allow the device as soon as it showed up. So it had no connectivity problems and should be reachable over IPv6, but that seems not to be the case.

 

Where in the Nighthawk RS300 admin panels can I find/determine IPv6 addresses of connected devices? Thanks!

    The printers configuration page could show networking status and information. Something to check with the printers mfr about. I know HP printers show IPv6 information when enabled and have IPv6 configuration support.

    so the only problem is the printer? 
    Factory reset it and just let it rock ipv4?

    Try testing here as well:

    test-ipv6.com

     

    If you have native IPv6 support from your ISP.

    Congratulations on reconnecting to the RS300 using IPv6.

     

    What does the printer itself say about the network connection?  (My Epson, for example, does not report having an IPv6 address.)

     

    Might try > netsh interface ipv6 show neighbors
