Plan downstream /48, /56, /64 assignments from a provider block.
Partition a provider IPv6 block into downstream assignments with nibble-boundary checks.
Total subnets: 65536
Nibble aligned: Yes
Nibble aligned — each delegation boundary falls on a single hex digit; ip6.arpa zones are clean.

IPv6 Nibble Boundary Planner helps you plan downstream /48, /56, /64 assignments from a provider block. It is commonly used by network admins, IT support teams, ops engineers for ipv6 subnet planner, nibble boundary, ipv6 allocation.
Validates /4 nibble alignment for clean reverse DNS delegation zones.
