What is the importance of subnet masking when routing IP datagrams?

  1. It lets a device decide whether the destination is located on the same local
    network segment.
  2. It matches remote IP-addressed interfaces to their hardware addresses beyond
    the router.
  3. It lets network hosts communicate with one another using an alternate
    link-layer address.
  4. It filters out remote networks from the routing table, allowing for efficient
    route map discovery.
