I used this addressing but in my project my teacher asked me where I got the ipv6 addressing from.
Do you think this addressing is wrong?

Not wrong. If you need to justify where you got the IP address from, you can use a guide like this below

Hello @dragunder
From my point of view, tour instructor is seeking clarification on the origin and logic behind the IPv6 addressing scheme you’ve implemented in your project. While the addresses themselves may not necessarily be incorrect, it’s important to understand and justify the type of IPv6 addresses you are using and their intended purpose. This ensures alignment with networking best practices and helps address any concerns your instructor may have.
IPv6 addressing is structured and allocated globally by the IANA. These addresses are typically distributed to regional internet registries, which in turn allocate them to ISPs and end-users. In an educational or lab setting, it is common to use either unique local addresses (ULAs) for internal communication. It’s important to avoid using random global unicast addresses unless they have been assigned to you or an organization.
So, review the type of IPv6 addresses you’ve implemented. For private, internal testing, ULAs that start with fc00::/7 are appropriate, as they are not routable on the internet. If you’re demonstrating link-level communication, ensure that fe80:/10 link-local addresses are used correctly within a single segment. For practice in global scenarios, stick to the documentation prefix to avoid conflicts or confusion.
Finally, ensure you document your IPv6 addressing scheme thoroughly. Provide clear reasoning for the type of addresses used and their purpose in the project. For example, mention if you are simulating a private network with ULAs or practicing global routing using the documentation prefix. This transparency will demonstrate your understanding of IPv6 best practices and provide your instructor with the necessary context to evaluate your project...
Good Luck.

@dragunder The IPv6 addressing you used (e.g., 2001:db8:10::/64) is correct for educational or documentation purposes, as 2001:db8::/32 is specifically reserved for such use (as per RFC 3849). Your teacher likely wanted you to clarify its origin because it is not a prefix allocated for real-world deployment. If this is for simulation or study, it's perfectly fine, but for a real network, you'd need an actual IPv6 prefix provided by an ISP or use private IPv6 addresses (e.g., fc00::/7).
