Para se ter uma ideia do que isto representa, se convertêssemos cada IPv6 possível em um cm 2, poderíamos envolver toda a superfície do planeta Terra com 7 camadas de endereços. Enquanto no IPv4 temos 32 bits que nos possibilitam cerca de 4 bilhões de combinações (2 32), no IPv6 temos mais de 340 undecilhões de endereços possíveis. The first 64 bits represent the network portion and the last 64 bits represent the interface id. IPv6 is the successor to a previous addressing infrastructure, IPv4, which had limitations IPv6 was designed to overcome. IPv6 addressing can reduce routing table size by allowing ISPs to aggregate customers' prefixes into a single prefix and present only that one prefix out to the IPv6 internet. Therefore, there is no compromise if we subnet the network. Aufbau einer IPv6-Adresse IPv6-Adressen bestehen aus 8 Blöcken zu 16 Bit mit jeweils vierstelligen hexadezimalen Zahlen. Bits: The next 16 bits (after the global routing prefix). An alternative format for IPv6 addresses combines the colon and dotted notation, so the IPv4 address can be embedded in the IPv6 address.
