What is subnet Wikipedia?
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.
What do you mean by subnets?
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. The Internet Protocol (IP) is the method for sending data from one computer to another over the internet.
How do subnets work?
A subnet, or subnetwork, is a network inside a network. Subnets make networks more efficient. Through subnetting, network traffic can travel a shorter distance without passing through unnecessary routers to reach its destination.
Why is subnetting important?
Benefits of Subnetting Subnetting divides broadcast domains, meaning that traffic is routed efficiently, improving speed and network performance. A subnet mask ensures that traffic remains within its designated subnet. This reduces major congestion and reduces the load imparted on the network.
What are characteristics of subnet?
Characteristics of Subnetting
- Network ID: It is the first IP address in each Sub-Network in the main network ID.
- Broadcast ID: This feature represents the last IP address in each Sub-Network in the network ID.
- First Host ID: The next IP address after the Network ID is represented by the First Host ID.
How many subnets are there?
To calculate the number of possible subnets, use the formula 2n, where n equals the number of host bits borrowed. For example, if three host bits are borrowed, then n=3. 23 = 8, so eight subnets are possible if three host bits are borrowed.
How do subnets talk to each other?
A subnet is just a range of IP addresses. All the devices in the same subnet can communicate directly with one another without going through any routers. In IPv4, a network interface is connected to only one subnet and has only one IP address.
What are the benefits of subnetting?
Subnetting is the practice of dividing up a network into two or more networks. Common advantages of subnetting include enhancing routing efficiency, network management control, and improving network security.
What are two advantages of subnetting?

How many hosts are in a subnet?
Class A
| Network Bits | Subnet Mask | Number of Hosts |
|---|---|---|
| /24 | 255.255.255.0 | 254 |
| /25 | 255.255.255.128 | 126 |
| /26 | 255.255.255.192 | 62 |
| /27 | 255.255.255.224 | 30 |
Can you subnet your home network?
Pretty much every home router uses a subnet that supports a maximum of 250 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 are some disadvantages of subnetting?
Subnetting decreases the total number of IP addresses in the network but may need buying additional hardware such as a router. So, it may cost lots of money. It cannot correct the lack of efficiency because companies still assign address block regarding to classes.
What are the advantages and disadvantages of subnetting?
Advantages of Subnetting It reduces network traffic by lowering the number of broadcasts sent out. It helps overcome limitations in a local area network (LAN), such as the maximum number of allowed hosts. It allows people to connect to a work network from their homes without having to open the entire network.
