How can I offer another interface IPv6 addresses?

I have two networks and their structures are as follows:

(network A) ISP router --- (eth1) - Raspberry Pi - (eth0) --- other devices like PC, smartphone, etc. (network B)

I want to assign IPv6 addresses to network B, but I have no idea how to achieve this.

Here's a list of IPv6 addresses on my Raspberry Pi:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 state UNKNOWN qlen 1000
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
    inet6 fe80::XXXX:XXXX:XXXX:XXXX/64 scope link
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
    inet6 2400:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/64 scope global deprecated dynamic mngtmpaddr noprefixroute
       valid_lft 21664sec preferred_lft 0sec
    inet6 fe80::XXXX:XXXX:XXXX:XXXX/64 scope link
       valid_lft forever preferred_lft forever

IPv6 has already been assigned to eth1, and I want to offer another one to eth0 and other devices as well.

What should I use? Dnsmasq, odhcpd, radvd, or wide-dhcpv6-client? I have no clue. So, I would be grateful if you could teach me in a way that's easier to understand.

By the way, I have Ubuntu 22.04.1 LTS installed on my Raspberry Pi.

What version of Ubuntu are you using, it matters.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
