The host part is mainly assigned to each host. By observing the network ID we can able to identify the class of the network. The network part will always specify the number that is assigned to it. They are called the network part and the other one is called the Host part. As we said earlier, the IP address can be divided into two different parts. Hence we can able to know the subnet mask by simply observing the IP address.Įach network consists of a unique network number, similarly, every machine has a unique IP address to it. So the IP address 222.111.222.111 belongs to class C. Class C is in the range between 192 to 223.
Let say another example like 222.111.222.111, which belongs to class C. Let say 118.52.42.6 which actually belongs to class A and it has the subnet mask of 255.0.0.0. Let us take another example to understand this in detail. Since the IP address belongs to class B then the subnet mask of class B is 255.255.0.0.įrom the IP address 129.13.220.13, we get to know that 129.13 is called the network id, and 220.13 is known as the host Id. We check to which class the Ip address belongs.īy observing the above IP address, we get to know that it belongs to the class B IP address. Now how can we identify the address with no subnet mask? We can able to identify it by simply observing the type of class it is.
There may also cause some of the questions that may come up like, if the subnet mask is undefined, how to figure out the subnet mask, or to use the subnet mask that is simply applied to any of the classes.įor suppose we have an IP address like 129.13.220.13 without any of the subnet masks. Class E ranges from 240 to 255 with an undefined subnet mask similar to class D. Class D ranges from 224 to 239 with the undefined subnet mask. And class C ranges from 192 to 223 with the subnet mask of 255.255.255.0. Class B ranges from 127 to 191 with the subnet mask of 255.255.0.0. The class A range is from 0 to 127, this range is called the octet range, it has a subnet mask of 255.0.0.0. Now, let us discuss the ranges of these subnet masks in detail. All these classes are of different ranges.
They are class A, class B, class C, class D, class E.
There are different classes in the subnet maks. Today, let us discuss the default subnet masks in detail. What Is The Default Subnet Mask For The Ip Address 203.111?Ģ55.255.255.0 is the default subnet mask for the Ip address 203.111.
