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? On 6/7/13, MarcoH <marcoh@marcoh.net> wrote:

Hi,
I'm not sure if this list is the right place but I can make at least several suggestions.
Of course this is the right place
You don't really say how big of an assignment you get, if it is a full /48 I would leave some more gaps to deal with future growth. And as the previous speaker suggested, think a bit about your aggregation strategy a bit. There are two ways of looking at it:
- Take a service oriented approach - Follow the structure of the network and aggregated for instance on buildings
There are also various documents online that can help you with this, one was written by Surfnet, the Dutch NREN, and is available at https://www.ripe.net/lir-services/training/material/IPv6-for-LIRs-Training-C...
And I'm sure there are people on this list who can help you, so hopefully there will be more responses.
Cheers,
