Set up NPTv6 in IPv6 on MikroTik

IPv6-to-IPv6 Network Prefix Translation (NPTv6) is a stateless, 1:1 translation mechanism that modifies only the network prefix of an IPv6 address, leaving the host identifier unchanged. Unlike traditional NAT, it preserves end-to-end connectivity by maintaining address transparency. This allows for: Local Prefix Control: Use stable internal addresses (e.g., ULA) regardless of ISP changes.…
