Hierarchical & Regional How does address distribution work?
Source: http://www.nro.net/wp-content/uploads/nro-stats-2012-q3.pdf IPv4 Address space status
Yes! There is a «running out fairly» policy in place, in order to preserve the last IPv4 address blocks in the region. On the 3 RIRs which haven’t still «exhausted» the assignment policy is still based on documented/proved needs. In the remaining two regions, the «running out fairly» policy is already active! No more than 1024 new IPv4 addresses per member/ISP. Have we really ran out?
RIR Allocation Policies AfriNIC: http://www.afrinic.net/IPv6/index.htm http://afrinic.net/en/library/policies/122-afpub-2004-v6-001 * APNIC: http://www.apnic.net/docs/index.html http://www.apnic.net/policy/ipv6-address-policy.html * ARIN: http://www.arin.net/policy/index.html http://www.arin.net/policy/nrpm.html#ipv6 * LACNIC: http://lacnic.net/sp/politicas/ http://lacnic.net/sp/politicas/ipv6.html * RIPE-NCC: http://www.ripe.net/ripe/docs/current-ripe-documents/ipv6-documents http://www.ripe.net/ripe/docs/ipv6policy.html * *describes policies for the allocation and assignment of globally unique IPv6 address space
A new ISP/company (in the RIPE/NCC service region) cannot get more than 1024 IPv4 addresses from the RIR Clearly not enough if you are planning a network for a reasonable amount of customers. The alternative is to find someone who is able to «transfer» address blocks For a reasonable price… Lack of offer may be a problem. Anyway, for continued growth on the public Internet, IPv6 is the only solution Implications
