/21 - 21 bits in network address represented by ones in binary address above. Leaves 2^11th power host addresses left (the zeros to the right).
Equals 2048 host addresses minus the two reserved addresses = 2046
When we express an IPv4 network address, we add a prefix length to the network address. The prefix length is the number of bits in the address that gives us the network portion. For example, in 172.16.4.0 /24, the /24 is the prefix length - it tells us that the first 24 bits are the network address. This leaves the remaining 8 bits, the last octet, as the host portion.
62 hosts.
IPv4 has 32-bits classified into 4 bytes out of which each byte is divided into network or hosts. Thus, it can have any combination like 1 host, 3 networks or 2 host, 2networks etc.
By default Class C subnet mask is 255.255.255.0 = 24 bits for network id and 8 bits for host id. in Binary 1111 1111. 1111 1111. 1111 1111. 0000 0000 Here all 1s are Network bits and all 0s are host bits. For this subnet mask you can have 256 hosts. And you can use 254 host and asign IP address to them. By Saurabh

A Class C IP address has 24 bits for network and 8 bits for host. So to have a subnet mask of 26 bits, you will need to use 2 bits from host part.Number of subnets is given by the formula : 2^(no. of bits used from host part).Hence number of subnets in this case would be = 2^2 = 4.For e.g. if the class C IP address is 200.168.210.0the 4 subnet addresses would be :11001000.10101000.11010010.00000000 = 200.168.210.011001000.10101000.11010010.01000000 = 200.168.210.6411001000.10101000.11010010.10000000 = 200.168.210.12811001000.10101000.11010010.11000000 = 200.168.210.192Note: The digits in bold are the mask bits.
Assuming IP version 4 (the current standard), a complete IP address has 32 bits. /16 means that the first 16 bits specify the network; the remaining bits (also 16 in this case - calculated as 32 minus 16) specify the host.Assuming IP version 4 (the current standard), a complete IP address has 32 bits. /16 means that the first 16 bits specify the network; the remaining bits (also 16 in this case - calculated as 32 minus 16) specify the host.Assuming IP version 4 (the current standard), a complete IP address has 32 bits. /16 means that the first 16 bits specify the network; the remaining bits (also 16 in this case - calculated as 32 minus 16) specify the host.Assuming IP version 4 (the current standard), a complete IP address has 32 bits. /16 means that the first 16 bits specify the network; the remaining bits (also 16 in this case - calculated as 32 minus 16) specify the host.
Thirty bits make up the network portion of a class C address. Three bits are borrowed for the subnet mask. There is also a class A and a class B that are comprised of bits.
There are a total of 126 networks with 16,777,214 addresses per network in a Class A Address of ipv4. Such a big range Ha!
The subnet mask. The subnet mask consists of a certain number of ones, followed by a certain number of zeroes (in binary). The ones tell you how many bits in an IP address make up the network part; the zeroes are for the host.The subnet mask.
