Identifying two addresses

How do you determine whether two addresses are in the same subnet?

The most common subnet you will see is 255.255. 255.0. So if two addresses match in the first three sections (reading left to right), and the subnet is 255.255. 255.0 for both addresses, they are in the same subnet.

How do you know if 2 pcs are on the same network?

You need to know the subnet mask. The subnet mask tells you which bits of the address represent the subnet, and which bits represent the host within the subnet. If your subnet is a /24 (255.255. 255.0), then any address whose first three octets match would be in the same subnet.

How do I compare two IP addresses?

The easiest way to determine the range is to convert the IP into a decimal format and then do the ordinary comparing statements necessary. You can do this by assigning a weight for each part of the IP. Each part has a maximum value of 255. Thus, the best weight you can choose is 256.

Can 2 IP addresses be the same?

All public IPs assigned to Routers of ISPs or Routers connecting to Internet are unique. but private IPs of two hosts can be the same if both are connected to different public networks. So the combination of public and private IP identifies your device uniquely.

How do you find if an IP address belongs to a subnet?


Quote from video: We ignore the octet in the IP address and we just write a 0. And then we're done with the octet. And we move on to the next one so here again we see another 0 in the third octet of the subnet mask.

Are all IP addresses the same on a network?

The external IP address is assigned by your ISP to your router which in turn assigns different internal IP addresses to all devices in the network. The outside world can only see your external IP address. In short, it cannot distinguish between your dad’s computer and yours.

How can I see other IP addresses on my network?

Follow these four simple steps to scan your network for IP addresses in use:

  1. Open a Command Prompt window.
  2. On Windows or macOS type ipconfig or on Linux type ifconfig. …
  3. Enter the command arp -a to get a list of all other IP addresses active on your network.

How do I see other devices on my network?

The best way to find this information will be to check your router’s web interface. Your router hosts your Wi-Fi network, so it has the most accurate data about which devices are connected to it. Most of the best routers offer a way to view a list of connected devices, although some may not.
