The octets are different - a class a is 255.0.0.0 and a class C is 255.255.255.0 for a default subnet mask. Of course, if you are subnetting then this doesn't apply.
If this is a default subnet mask, then it would be a class C subnet mask. If you are subnetting a network and this is not the default subnet mask, then it could be either a class A or class B.
The default subnet mask for a class C IP address is 255.255.255.0
The default subnet mask for a Class C network is 255.255.255.0. This is sometimes expressed as A.B.C.D/24 where the /24 represents the 24 bits of the subnet mask.
The standard default subnet mask for class C is 255.255.255.0 and the range of addresses is from 192 - 223
Look at the first octet value and check the corresponding range. 1-126 class A, subnet mask 255.0.0.0 128-191 class B, subnet mask 255.255.0.0 192-223 class C, subnet mask 255.255.255.0
The no. of IP's that can be assigned to single computer depends on the subnet mask. if the subnet mask is of A class then the IP's assigned can be 16777216. If the subnet mask is of B class then the no. of IP's that can be assigned is 65536. And if the subnet mask is of C class then the IP's assigned can be 254.
There is no single default subnet mask; it depends on the class network you are using. Class A 255.0.0.0 Class B 255.255.0.0 Class C 255.255.255.0
it is a class c address..so default subnet mask is 255.255.255.0 it is a private address...
220.127.116.11 is a class C network. The subnet mask would be 255.255.255.0 and the network address is 18.104.22.168
Class C network if you are not subnetting.
