What does 24 mean in IP address?

The number after the slash represents the number of consecutive 1’s in the subnet mask. For example, 192.168.10.0/24 is equal to the network 192.168.10.0 with a 255.255.255.0 subnet mask. If you convert 255.255.255.0 to binary, you end up with 24 consecutive 1 ‘s: 11111111.11111111.11111111.00000000.

IPv4 addresses are usually represented in dot-decimal notation, consisting of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 172.16. 254.1. Each part represents a group of 8 bits (an octet) of the address.

What is subnet simple words?

A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments. … Each computer, or host, on the internet has at least one IP address as a unique identifier.

How do I find my IP subnet?

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 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. So why the secondary page?

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!).

What is IP subnet and gateway?

A gateway IP refers to a device on a network which sends local network traffic to other networks. … The subnet mask number helps to define the relationship between the host (computers, routers, switches, etc.) and the rest of the network.

What is the first part of an IP address called?

Class A Network The first 8 bits (the first octet) identify the network and the remaining 24 bits indicate the host within the network. An example of a Class A IP address is 102.168. 212.226, where “102” identifies the network and “168.212. 226” identifies the host on that network.

What is the same subnet?

On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100. 100. would be part of the same subnet. Dividing a network into subnets is useful for both security and performance reasons.

Why is subnet mask 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 classless IP?

Classless Addressing is an improved IP Addressing system. It makes the allocation of IP Addresses more efficient. It replaces the older classful addressing system based on classes. It is also known as Classless Inter Domain Routing (CIDR).

What is subnet in IP address?

A subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with an identical most-significant bit-group in their IP addresses.
