I'm trying to understand how IPv6 networks work.
I have been assigned a 2001: /128 address by Comcast (my ISP) for my internet facing cable modem (c300-100NAS Netgear).
I have received a system delegated prefix of 2601:243:1501:xxxx::/60 and a LAN deligated prefix for my internal network 2601:243:1501:xxxx::/64
This automatically assigned IP address of 2601:: /64 network to all devices in my internal network at home. I can even connect to each other using these IP addresses. But when i access these from the internet, i am not able to reach them. I think i am missing the routes for the 2601 /64 networks that lead into my home. (these are acting similar to ipv4 private addresses)
Q1: what is the difference between system and LAN deligated prefixes
Q2: What should i do to be able to access my machines over the internet using 2601::/64 address. I am typically looking to use ssh and http ports.
Thanks for your help in advance.
- Internet browsing over ipv6 works.
- My internal machines (ubuntu linux) both pass the ipv6 tests.
- what is my ipv6 displays my 2601::/64 ip address.
- Both machines can talk to each other over ipv6 but only internally behind the router.
