IPv6
IPv6 Internet Protocol version 6 ( IPv6 ) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 provides other technical benefits in addition to a larger addressing space. In particular, it permits hierarchical address allocation methods that facilitate route aggregation across the Internet, and thus limit the expansion of routing tables . The use of multicast addressing is expanded and simplified, and provides additional optimization for the delivery of services. Device mobility, security, and configuration aspects have been considered in the design of the protocol. IPv6 addresses are represented as eight groups, separated by colons, of four hexadecimal digits. The full representation may be shortened for example, 2001:0db8:0000:0000:0000:8a2e:0370:7334 becomes...
