What Is IP Subnet Mask?

What is IP subnet?

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..

What is your 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 are the 4 parts of an IP address?

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 are the 3 classes of subnet mask?

The three default subnet masks are 255.0. 0.0 for Class A, 255.255. 0.0 for class B, and 255.255. 255.0 for Class C.

What is IP address and subnet mask?

A subnet mask is a 32- or 128-bit number that segments an existing IP address in a TCP/IP network. … Subnet mask divides the IP address into a network address and host address, hence to identify which part of IP address is reserved for the network and which part is available for host use.

How do you find the subnet mask of an IP address?

255.248 or /29.STEP 1: Convert to Binary.STEP 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask. … STEP 3: Find Host Range. … STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet.

What does 8 mean in IP address?

A network numbered “10.0. 0.0/8” (which is one of those reserved for private use) is a network with eight bits of network prefix, denoted by “/8” after the oblique. The “8” denotes that there are 24 bits left over in the network to contain IPv4 host addresses: 16,777,216 addresses to be exact.

How many subnets are in a 24?

Converting /29 gives 255.255. 255.248. This shows that the fourth octet is the interesting octet. Deducting 248 from 256 gives us 8 so the subnets are 0, 8, 16, 24, 32, 40, 48……2-3 Subnetting.Dotted Decimal ValueCIDR notation255.255.255.0/24255.255.255.128/25255.255.255.192/26255.255.255.224/2719 more rows•Dec 12, 2013

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.

How does IP subnet work?

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 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 subnet mask in simple words?

A subnet mask is a number that defines a range of IP addresses available within a network. A single subnet mask limits the number of valid IPs for a specific network. Multiple subnet masks can organize a single network into smaller networks (called subnetworks or subnets).

What is IP and its types?

An internet protocol (IP) address allows computers to send and receive information. There are four types of IP addresses: public, private, static, and dynamic. An IP address allows information to be sent and received by the correct parties, which means they can also be used to track down a user’s physical location.

How do I change my subnet mask?

To change the subnet IP address, type a new value in the Subnet IP text box. The address should specify a valid network address that is suitable for use with the subnet mask. To change the subnet mask, type a new value in the Subnet mask text box. Click OK to save your changes.

What is a 16 subnet?

The last three octets of a Class A subnet mask are used to address hosts on a LAN; the 24 bits you can manipulate however you wish. … It saves you from typing, or pronouncing, the whole mask. For example, /8 means 255.0. 0.0, /16 is 255.255. 0.0, and /24 is 255.255.
