NETMASK nedir özellikleri nelerdir
NetmaskA netmask is a 32-bit mask used to divide an IP address into subnets and specify the networks available hosts. In a netmask, two bits are always automatically assigned. For example, in 255.255.225.0, "0" is the assigned network address; and in 255.255.255.255, "255" is the assigned broadcast address. The 0 and 255 are always assigned and cannot be used.
Below is an example of a netmask and an example of its binary conversion.
Netmask: 255. 255. 255. 255
Binary Conversion: 11111111 11111111 11111111 11111111
Netmask length 8 16 24 32
Counting out the bits in the binary conversion allows you to determine the netmask length. In the above example you have an example of a 32-bit address. However, this address is a broadcast address and does not allow any hosts (computers or other network devices) to be connected to it.
A commonly used netmask is a 24-bit netmask as seen below.
Netmask: 255. 255. 255. 0
Binary Conversion: 11111111 11111111 11111111 00000000
Netmask length 8 16 24 --
