What are the valid subnets?
Answer: The valid hosts are the numbers between the subnet number and the mask.
For the 64 subnet, the valid host range is 64-126.
For the 128 subnet, the valid host range is 129-190..
What is the correct formula for calculating the number of usable host IP addresses in a subnet?
To calculate the number of possible hosts per subnet, use the formula 2h – 2, where h equals the number of host bits. The reason two addresses must be subtracted is because of the network address and the broadcast address. There are two ways to determine the number of host bits.

What is a 192.168 IP address?
The IP address 192.168. 0.1 is one of 17.9 million private addresses, and it’s used as the default router IP address for certain routers, including some models from Cisco, D-Link, LevelOne, Linksys, and many others.
What does it mean 192.168 0.0 24?
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.
Why is 192.168 always used?
The reason why most routers come setup with a Class C IP address is because it can still handle over 65,000 IP addresses, enough for just about any home or small business. The first usable address in the Class C network is 192.168. … Note that there are other private IP address ranges, such as 1.0. 0.0/8 and 2.0.

What does 192.168 mean?
Using 192.168. 192.168. 0.0 is the beginning of the private IP address range that includes all IP addresses through 192.168. 255.255. This IP address is usually not used on a network, and a phone or computer wouldn’t be assigned this address.
How do I find the range of a usable IP address?
If you break down the IP given to you to binary, the network address is the ip address where all of the host bits (the 0’s in the subnet mask) are 0,and the last address, the broadcast address, is where all the host bits are 1. Invert mask (XOR with ones), AND it with IP. Add 1. This will be the starting range.
How do you calculate hosts per subnet?
Calculating the maximum possible number of hosts in a subnet: To find the maximum number of hosts, look at the number of binary bits in the host number above. The easiest way to do this is to subtract the netmask length from 32 (number of bits in an IPv4 address). This gives you the number of host bits in the address.

What does 24 mean in IP address?
This is called “slash notation”. There is a total of 32 bits in IPv4 address space. For example, if a network has the address “192.0. 2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated.
What is IP subnetting?
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.
