  • The subnet mask tells us which part of the IP address is the network and host part, the host that uses 192.168.1.1 sees that 192.168.1.2 is using the exact same network address and will know that it can use ARP to find the MAC address, create an Ethernet frame, encapsulate the IP packet and send it towards the switch.
  • The format of the IP address would be “dotted”, e.g. 255.254.0.0 (like written in the blog post). If you want to convert multiple IP addresses you can put them into a file (one by a line) and then read them with `Get-Content` and pipe them to the method like this: `Get-Content myAddresses.txt | % { Convert-IpAddressToMaskLength $_ }`.

  • I think for this to get it right, you would have to change the is_private check for networks to iterate over each possible subnet and check if that is in the private networks list. This takes an unfeasibly long time. So, we would probably have to add special cases for these networks, unless people have better ideas. msg382990 -

From an IP routing and IP forwarding standpoint a subnet is atomic, though there may be repeaters, hubs, bridges, or switches between the physical interfaces of subnet members. Bridged IP Subnet: A bridged IP subnet is one in which two or more physically disjoint media are made to appear as a single IP subnet.
