[ipv6-wg] Request to verify ipv6 addressing scheme in my diagram

Hi Marco,

I have assumed that a fixed /48 prefix is provided by the ISP to the
organization. It is  2001:0A5D:4B1A::/48

Then, the network IDs (fourth field in address) are  decided by the
organization themselves and 2001:0A5D:4B1A:A120::/64 is the one that
connects to Internet i.e. to ISP's edge router.

Internally in organization, since NAT is not being used in IPv6, all
of the routers will have public IPs. So, I have tried to change fourth
field of the addresses and assigned to each interface of internal
devices. Had it been IPv4, I would have used just one public address
and all the internal interfaces would have private addresses. However,
not having NAT is confusing me. Probably that's why I am not
understanding what is meant by aggregating the IPv6 addresses at
buildings.

I am studying the IPv6-for-LIRs-Training-Course/IPv6_addr_plan4.pdf
for more understanding. But can you please correct my understanding
with an example?

Thanks
Maninder Singh

P.S. - Is this just an email based forum or do we have web based forum
where all responses can be seen? I have received just two responses.
Seems like I have missed many. Can you please send a link where can I
actively participate in this forum?
