How does IPV 6 works? Residency
Hello I got a question.
I have a connection in France 1Giga and they offer also IPV6 like 60 of them
How can I use them on 1 Pc?
Example When i get a VPS that has /64 ipv6
I can add more IPv6 to my VPS system and do my work.
I cant do the same to an Ubuntu local System I get only 1 IPV6 and 1 IPV4
But if i connect another Device the Device gets the same Ipv4 (normal) and a different IPV6
SO question is how Can i Enable more Ipv6 to the Same PC System
Its extremely inconvinient to get new device for each IPV6 usage
Note: Im Big newbie on how it works and why.

@yoursunny waiting ur answer
Usually, your router is the one that gets the whole range (whether /64 or /48 or similar) and then chooses to delegate that to clients in whatever way it deems fit. To get more IPv6 on a single machine you would probably need to configure your router to hand out larger prefixes. That process and whether its possible in the first place will depend heavily on your routers software.
I guess you can use macvlan if you need more IPv6 addresses assigned with SLAAC to the same Debian host.
That fast answer. I need to look it up thanks, Although i never saw any setting that even implies that
I think this might be the right place to start to read, to get a general idea: https://openwrt.org/docs/guide-user/network/ipv6/configuration
From the link:
”auto: (default) enable IPv6 on the interface. Spawn a virtual interface wan_6 (note the underscore) and start DHCPv6 client odhcp6c to manage prefix assignment. Ensure the lan interface has option ip6assign 64 (or a larger prefix size) set to redistribute the received prefix downstream.”
It would still allocate the same number of IPv6 per MAC.
I am not sure the ISP would allow more per MAC as they include the MAC address most of the time in their body (the IPv6s). You could try to manually add the next one up or down and see if you can ping it. If it works, then your provider does not filter, if it doesn't, then you are out of luck.
Personally I create many VMs and each has own MAC and can have many virtual interfaces, therefore multiple IPv6 if I would want to. I don't create the VMs for the IPv6, though, that is just a bonus.
