Hi every body.
Let say ICANN assigns 2340::/12 to ARIN
ARIN in turn makes the following assignment to Lir
2340:1111 /32 Isp1
2340: 2222/32 isp 2
those isps then further divide the address space to small isps and end users.
2340::/12 prefix should be advertised to other isps in different geographical regions say Europe. Consequently we want isps in Europe to know only one prefix 2340/12 rather than individual prefix such as 2340:1111/32, 2340:2222/32 to make routing table smaller. But who will advertise this prefix to isps in Europe ? ARIN? but ARIN is only tasked to assign ip addresses to its customers from its assigned blocks . Will this job be delegated to some isp?
thanks and have great day.
