What is my IP and subnet mask?
The most simple way to find your own subnet mask is to run a simple command line in windows.
Simply press the Windows key and “R” at the same time to open the command prompt and type “cmd” followed by “enter.” This will allow you to see your subnet mask (as shown below!)..
Is subnet mask always 255?
hmm Almost every small network uses a subnet mask of 255.255. 255.0 and this allows for 255 IP addresses on that network. … A subnet mask is a binary mask made up of all 1, contiguous.
What is a 255.255 254.0 subnet?
255.255.254.0 = 23 bits mask = 510 hosts (512 -2 ) 255.255.252.0 = 22 bits mask = 1022 hosts (1024 -2 ) 255.255.248.0 = 21 bits mask = 2046 hosts (2048 -2) You always multiply by 2 or divide by 2..and remove 2 hosts (broadcast and network)
What is a 255.255 subnet?
A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). … This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.
How do I know my subnet mask?
In the Windows search fields, type cmd, to open command prompt.Press Enter.Type ipconfig/all press Enter.Find your network settings.Your PC’s IP address and your network Subnet Mask and Gateway will be listed.
What is subnet mask and why it is used?
A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP (Internet Protocol) address and see how it is organized.
What is subnet mask with example?
A common example of a subnet mask for class C IP addresses is 255.255. 255.0, the default subnet mask for many computers and network routers. When applied to subnet, a subnet mask shows the routing prefix.
Why subnetting is required?
The main purpose of subnetting is to help relieve network congestion. Congestion used to be a bigger problem than it is today because it was more common for networks to use hubs than switches. When nodes on a network are connected through a hub, the entire network acts as a single collision domain.
What is a 192.168 IP address?
Using 192.168. 192.168. 0.0 is the beginning of the private IP address range that includes all IP addresses through 192.168. … One common IP address assigned to home routers is 192.168. 1.1. This IP address is used because the router is on the 192.168.
What is a 255.255 0.0 subnet?
A subnet of 255.255. 0.0 would give you lots of hosts (approx 216) and 256 networks. A3 – the network has 8 bits and so does the node component. This means that you have have 28 =256 networks and 256 -2 = 254 hosts.
