IPv6

The latest version of the Internet Protocol, designed to replace IPv4. IPv6 uses 128-bit addresses (e.g., 2001:0db8::1) compared to IPv4's 32-bit addresses (e.g., 192.168.1.1), providing a vastly larger address space. IPv6 eliminates the need for NAT, includes built-in IPsec support, and simplifies routing. DNS AAAA records map domain names to IPv6 addresses. Dual-stack deployments run IPv4 and IPv6 simultaneously during the transition.
