The world is running out of IP(v4) addresses. IP addresses are globally managed by IANA, which assigns addresses to the five registries.
APNIC (Asia/Pacific’s Internet registry) and RIPE (Europe’s Internet registry) have already depleted their address pools. ARIN (North America’s Internet registry, have 5 /8 IPv4 address pools left which is expected to be depleted very soon.
ARIN will not be able to assign anymore IPv4 addresses to the ISPS. IPv6 address space is the address of our future. Now is the time to plan and implement IPv6 in the service provider and enterprise networks if not already done. IPRoutes LLC can be your parner in planning, designing and implementing IPv6 addresses in your network.
