Getting Started with IPv6 on HughesNet

I've recently had HN installed at my home. It was disappointing to learn that gen5 technology doesn't allow the use of IPv4 based dynamic DNS services, but I guess good for them for embracing the fut...

    Hi Matt, 

     

    I'm glad you found the community, thank you for posting. I checked with our top network engineer on this and this was his input on the matter:

     

    The user is correct that he can’t use the fd0d:: ULA address to access from the outside.  However, Hughes does provide a 2001:5b0:: prefix that is globally routable and can be reached from the outside. 

    While the prefix can be found on the terminal (as LAN prefix; not WAN prefix), the actual IPv6 address that the user needs to use is the one assigned to whatever device the user is trying to access.  E.g., windows : ipconfig; linux: ifconifg, etc.

    This is different than IPv4 because there is no NAT in between the end device and the Internet with IPv6.

    Because this prefix and, thus, the IPv6 address of the device, can and does change, a dynamic DNS service is needed to use a name to map to current IPv6 address.

     

    Hope that sheds light on your concern!

        I stand corrected. I have tried a couple of 2001:5b0 addresses with no luck - might be just that I'm using the modem's address and not the actual end device... something new to play with.
