IPv4 Iterator

Hard48 minPremium Asked at OpenAI

    Walk IPv4 address space lazily, the way an allowlist or a scanner has to: ranges in either direction, CIDR blocks up to all four billion addresses, the smallest set of blocks that covers a range, and exclusions you jump over instead of stepping through.

    The five steps
    1. Walk a range 8 min
    2. Steps and reverse 9 min
    3. CIDR blocks 10 min
    4. From a range to blocks 10 min
    5. Skip what is excluded 11 min
