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 is IP loopback address?

A loopback address is a special IP address, 127.0. 0.1, reserved by InterNIC for use in testing network cards. This IP address corresponds to the software loopback interface of the network card, which does not have hardware associated with it, and does not require a physical connection to a network.

Is my IP public or private?

Difference between Private and Public IP address:PRIVATE IP ADDRESSPUBLIC IP ADDRESSIt is used to communicate within the network.It is used to communicate outside the network.Private IP addresses of the systems connected in a network differ in a uniform manner.Public IP may differ in uniform or non-uniform manner.8 more rows•Jul 30, 2019

What is difference between subnet and subnet mask?

Subnet Mask — A 32-bit number used to distinguish the network and host portions of an IP address. Subnet or Subnetwork — A smaller network created by dividing a larger network into equal parts. TCP/IP — Used broadly, the set of protocols, standards and utilities commonly used on the Internet and large networks.

Why do we need subnet mask?

9 Answers. We need a subnet mask for IPv4 addresses because the address doesn’t give any information on the network size. Class sizes are not the network sizes. … 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.

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 example?

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 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.

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.

What does it mean 192.168 0.0 24?

1. 192.168.0.0 Refers to the IP adress /24 refers to the subnet. / 24 subnet is 255.255.255.0. 192.168.0.0/24 is common for home networks.

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 subnet mask means?

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 a good subnet mask?

This is a simplistic explanation, good enough for handling a subnet like 192.168. 0.1 with a mask short hand value of /24 thru /32 (long hand 255.255. 255.0 thru 255). The subnet calculator can determine the range of the clients local network by its IP address and network mask.

How do you create a subnet?

In the Subnets tab, click Create. 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 subnet mask and gateway?

on a network. … 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.
