You need ,IP, address or network address with subnet ,mask, to calculate broadcast address, only the ,mask, /27 is not enough information. The broadcast address for an IPv4 host can be obtained by performing a bitwise OR operation between the bit complement of the subnet ,mask, and the host’s ,IP, …

An alternative to CIDR notation for ,masking, is simply providing a subnet ,mask, in ,IP, notation as follows: A. 10.0.0.255/24 B. Address: 10.0.0.255 Subnet ,Mask, 255.255.255.0 Here both A and B represent the same information. To see what this is doing, we can convert into binary notation:

The subnet ,mask, is the one which identifies the Network Part portion of the ,IP, address assigned to the host. For our example above, the host with ,IP, 10.0.0.2 is assigned also a subnet ,mask, 255.255.255.0. If you do a logical AND operation between the ,IP, address and the subnet ,mask,, you will find the Network potion of the address:

13/7/2017, · A subnet ,mask, is a 32-bit number used to differentiate the network component of an ,IP, address by dividing the ,IP, address into a network address and host address. It does so with bit arithmetic whereby a network address is bit multiplied by the subnet ,mask, reveal the underlying subnetwork.

In as much as there are a great number of articles on the subject of subnetting, I have also taken a bold step in creating a step by step guide “How to Calculate Subnet ,Mask, from ,IP, Address Step by Step” to bring you the understanding I have gained in the real world where subnetting is concerned.

IP Mask, Types A) ,Internet Protocol, (,IP,): Every user on Internet is identified by an ,IP, address. ,IP, means ",Internet Protocol,". This ,IP, can be alphanumeric (i.e: @host.beginner.es) or numeric (i.e: @177.75.82.11). These are assigned by your ISP provider and read by the server.
