What Is The Meaning Of Subnet Mask?

What does the mask 255.255 0.0 tell you?

A subnet mask is used to tell the network devices (whether it be the computer or any routers, modems, etc.) …

Likewise, if the subnet mask is 255.255.

0.0, then the computer will assume that every IP address in its local network will be in the format of 192.168.

Why do we need subnet mask?

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 address and see how it’s organized.

What is purpose of subnetting?

Subnetting ensures that traffic destined for a device within a subnet stays in that subnet, which reduces congestion. Through strategic placement of subnets, you can help reduce your network’s load and more efficiently route traffic.

What is Subnet example?

You can determine the number and type of IP addresses any given local network requires based on its default subnet mask. An example of Class A IP address and subnet mask would be the Class A default submask of 255.0. 0.0 and an IP address of 10.20. 12.2.

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 my public IP?

The public IP address is the Internet Protocol address, logged by various servers/devices. This is when you connect to these devices through your internet connection. This is the same IP address that we show on our homepage.

What is subnet mask and why it is used?

An IP address has two components, the network address and the host address. A subnet mask separates the IP address into the network and host addresses (). … It is called a subnet mask because it is used to identify network address of an IP address by perfoming a bitwise AND operation on the netmask.

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 IP address and subnet mask?

An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits).

How do subnets work?

Subnetting works by applying the concept of extended network addresses to individual computer (and another network device) addresses. An extended network address includes both a network address and additional bits that represent the subnet number.

What are the 4 parts of an IP address?

IP Address ComponentsAddress Class. Early in the development of IP, the IANA (Internet Assigned Numbers Authority) designated five classes of IP address: A, B, C, D, and E. … Default Subnet Mask. … The Network Field. … The Host Field. … Non-default Masks. … The Subnet Field.

Is subnet mask always 255?

All subnet masks must end in 0, 128, 192, 224, 240, 248, 252, 254, or 255—the values of each bit position as they are “turned on” left to right in any octet.
