On February 3, 2011, the Internet Assigned Numbers Authority (IANA) allocated the last five remaining “/8”s of IPv4 address space to the Regional Internet Registries (RIRs); the local registries are running low on IPv4 addresses, rapidly.
The advent of new Internet-connected locations (from hotels to planes and more world-wide) and new Internet-connected devices (notable examples include smartphones, smart meters, gaming devices and other household appliances) has exacerbated the shortage. Each of these extra devices places greater pressure on the existing IPv4 infrastructure.
In this white paper you will learn about various techniques for IPv6 Migration, IPv4 Preservation and IPv4/IPv6 Translation such as Carrier Grade NAT (CGN/CGNAT), Dual-Stack Lite (DS-Lite), NAT64, DNS64, 6rd and SLB-PT.
