# Does Each Subnet Need A Router?

## What is the difference between subnet and subnet mask?

A subnet denotes a range of addresses that can be allocated to hosts, such as 192.168.

The subnet mask is the classical way of representing which bits are part of the network portion of the address vs.

the host bits of the address.

The subnet mask for a /24 network is 255.255..

## 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.

## Is 192.168 private or public?

192.168. Note that only a portion of the “172” and the “192” address ranges are designated for private use. The remaining addresses are considered “public,” and thus are routable on the global Internet.

## How do you subnet?

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 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.

## Can a router have 2 IP addresses?

Routers are special because they have two IP addresses. An IP address is assigned to each of the router’s two “interfaces”. The first router interface is called the WAN (Wide Area Network) interface. This is the side of the router that faces the Internet and has a public IP address.

## 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.

## Can two hosts have same IP?

An IP conflict occurs when two or more hosts in the same subnet are configured with the same IP address. When this happens, communications with the two conflicting hosts are mixed up. One host may receive packets that belong to the other one, and vice versa.

## Can you have 2 different subnets on the same switch?

Switches can carry as many subnets as you want them to because they don’t know, or care, about IP routing. It’s actually fairly common in small setups to have a router (“gateway”) with multiple IP addresses, one per subnet, on a single Ethernet port.

## How do I know if my IP is public or private?

Public IP address are the IP addresses which have to registered before use. IANA is responsible for register these IP addresses to the organizations. Private IP address are the IP addresses which are reserved by IANA and they are not routable in the internet. These addresses will be not assigned to any organizations.

## What does subnet mask 255.255 255.0 tell a router?

A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). … This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.

## Where is subnet mask for router?

Find the subnet mask. This is located in the section titled “Ethernet adapter Local Area Connection.” Find the line beginning “Subnet Mask” and look across to find your subnet mask. Most subnet mask numbers begin with a string of 255s, such as 255.255. 255.0.

## How do I find the subnet mask of my router?

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.

## Can 2 different subnets talk to each other?

Devices in different subnets can communicate. That is the purpose of a router. Routers route packets between different networks. Even if devices in different networks are on the same layer-2 broadcast domain, you need a router to let the devices communicate at layer-3.

## How many subnets can a router have?

Pretty much every home router uses a subnet that supports a maximum of 250 (give or take) connected devices. A subnet that allows for 250 devices is specified with the first three numbers of the four numbers in an IP Address with an X serving as a wildcard. For example, very popular subnets are 192.168. 0.

## What is a router 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. … This results in the logical division of an IP address into two fields: the network number or routing prefix and the rest field or host identifier.

## Can two hosts different subnets communicate without router?

Is it possible to communicate two hosts with the same IP address but different subnet mask without adding a router? … Generally speaking, no two devices should have the same IP address unless they are behind a NAT device. Computers need routers to communicate with devices that are not on their same logical subnet.
