Understanding IPv6
IPv6 (Internet Protocol version 6) is the successor to IPv4. It uses a 128-bit address space, allowing for 2^128 (approximately 3.4 x 10^38) unique addresses. This vast space eliminates the need for Network Address Translation (NAT) and enables a more efficient, hierarchical routing structure.
