What is an example of a subnet mask Class C?
Class C networks use a default subnet mask of 255.255. 255.0 and have 192-223 as their first octet. The address 192.168. 123.132 is a class C address.

How many subnets are in a class C address?
Class C 4-bit subnetting
| Subnet Bits | Subnet Mask | Total Subnets |
|---|---|---|
| 0 | 255.255.255.0 | 1 |
| 1 | 255.255.255.128 | 2 |
| 2 | 255.255.255.192 | 4 |
| 3 | 255.255.255.224 | 8 |
How is subnetting calculated?
Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.
What is subnet mask with example?
You can determine the number and type of IP addresses any given local network requires based on its default subnet mask. An example of Class A IP address and subnet mask would be the Class A default submask of 255.0. 0.0 and an IP address of 10.20. 12.2.
What is IP address explain subnetting with example?
IP Subnetting is a process of dividing a large IP network in smaller IP networks. In Subnetting we create multiple small manageable networks from a single large IP network. Let’s take an example. If we put less hosts then remaining addresses will be wasted.
What is network address in subnetting?
Subnet addressing allows an autonomous system made up of multiple networks to share the same Internet address. The subnetwork capability of TCP/IP also makes it possible to divide a single network into multiple logical networks (subnets). The first 8 bits contain the network address (always beginning with a zero).
What is subnet example?
What is subnetting formula?
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.
What is subnetting explained with example?
The practice of dividing a network into two or more networks is called subnetting. For example, 198.51.100.0/24 is the prefix of the Internet Protocol version 4 network starting at the given address, having 24 bits allocated for the network prefix, and the remaining 8 bits reserved for host addressing.
