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 Mask example?

Example: A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.

Why is subnet mask needed?

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.

Is Gateway same as IP address?

The gateway has two IP address. One is an external IP address assigned by your ISP (internet service provider), and the other an internal IP address that is only accessible within your network. This internal IP address is also called you default gateway IP address (GW).

What is subnet mask in networking?

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 the use of Gateway?

A gateway is a node (router) in a computer network, a key stopping point for data on its way to or from other networks. Thanks to gateways, we are able to communicate and send data back and forth. The Internet wouldn’t be any use to us without gateways (as well as a lot of other hardware and software).

What is Gateway with example?

A gateway is a hardware device that acts as a “gate” between two networks. It may be a router, firewall, server, or other device that enables traffic to flow in and out of the network. For example, a proxy server may only allow local computers to access a list of authorized websites. …
