Splet26. nov. 2024 · One of the most obvious differences between IPv4 and IPv6 is the size of address space. IPv4 contains 32 bits and supports 4 billion (4 x 10 9) hosts. IPv6 contains 128 bits and supports 340 undecillion (340 x 10 36) hosts. IPv6 addresses are not represented in dotted decimal notation as with IPv4 addresses. SpletIPv4 and IPv6 are Internet layer protocols that define packet-switched inter-networking, including source-to-destination datagram transmission across multiple networks. The switch supports IP version 4 (IPv4) and IP version 6 (IPv6). IPv6 is described by RFC 2460: Internet Protocol, Version 6 (IPv6) Specification.
