if we need to conect few no.of host means we will go for class A ... because to reduce the IP wastage
The First Octet is used to derive the Class of an IP address...... Eg: 192.168.1.1------ The IP class for this IP add is CLASS "C" as the first Octet is 192.
An IPv4 address of 75.76.77.68 is considered a Class A address. A class A address ranges from 1.0.0.0 to 126.0.0.0
Class A IP address.
Class B, if you are referring to classful addressing schemes.
192.168.0.254 is a valid "class C" IP address.
There are five IP classes that IP addresses are divided into. The IP address 185 is a class B address. Class B IP addresses have the first three numbers of 128 to 191.
16
The offset for a Class C IP address is 24 bits.
This type of IP address is sometimes referred to as a link local address. It is used by computers when they do not have an address that was manually configured or the computer was not told what address to use on that network.
The IP address 10.10.10.1 belongs to the private IP address range defined by the Class A network. A common subnet mask used with this address is 255.255.255.0, which allows for 256 IP addresses within the subnet (from 10.10.10.0 to 10.10.10.255). Other subnet masks, such as 255.255.0.0 (Class B) or 255.0.0.0 (Class A), can also be used, depending on the specific network design requirements.
Class a
24 bits (8 bits per octet, so 3) are used for the network portion of a class C IP address
