What Is Your Subnet Mask?

Why is the subnet mask so important?

Also to be clear the purpose of the subnet mask is to determine which hosts are on the local network and which are outside of the network.

Hosts can talk directly to hosts on the same network, but they need to communicate with a router to talk to hosts on external networks..

In the Create Subnet dialog box, specify subnet details, such as the name, subnet IP address or subnet mask, range of IP addresses, gateway address, and broadcast domain. You can specify the IP addresses as a range, as comma-separated multiple addresses, or as a mix of both.

What is the difference between IP address and gateway?

IP address is an address by which you (or more specifically, your computer) are recognised on a network. Default gateway is the address of your router/ modem. It is common for all the devices connected to same network.

A subnet denotes a range of addresses that can be allocated to hosts, such as 192.168. … The subnet mask is the classical way of representing which bits are part of the network portion of the address vs. the host bits of the address. The subnet mask for a /24 network is 255.255.

How do I calculate my subnet mask?

Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.

What is subnet mask with example?

Subnet masks are also expressed in dot-decimal notation like an address. For example, 255.255. 255.0 is the subnet mask for the prefix 198.51. 100.0/24. Traffic is exchanged between subnetworks through routers when the routing prefixes of the source address and the destination address differ.

What is a subnet mask and how is it 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.
