Ipcalcactually does a lot more – it takes an IP address and netmask and provides the resulting broadcast, network, Cisco wildcard mask, and host range. You can also use it as a teaching tool to present subnetting results in an easy to understand binary values. Some of the uses ofipcalca...
Host address - 10.0.0.0 Host address (decimal) - 167772160 Host address (hex) - A000000 Network address - 10.0.0.0 Network mask - 255.255.255.0 Network mask (bits) - 24 Network mask (hex) - FFFFFF00 Broadcast address - 10.0.0.255 Cisco wildcard - 0.0.0.255 Addresses in network - 256 ...
Broadcast: 127.255.255.255 01111111. 11111111.11111111.11111111 Hosts/Net: 16777214 Class A, Loopback Try it for yourself — you can ping any address in this range.ping localhostreturns 127.0.0.1 because most Linux distributions configure this in/etc/hosts. Sorry, but that’s all the fun we can...
Since, while using a subnet masks, the host ID can not be all 0s (that represents the network address), or all 1s (that represents the network broadcast address), the above IP is not a host IP, but a broadcast IP of the IP subnet address. CIDR notation Traditionally, an IP address...
The subtraction of 2 accounts for the first IP address in a subnet, which is reserved to identify the network, and the last IP address reserved as the broadcast address. 1. Find host range To use the host's formula, let's first look at an example. Suppose you ...
So now we have the broadcast address in binary. Converting this to decimal will result in 192.168.116.63. We can also calculate a range of valid host IP addresses in a subnet using the binary method. For example if need to calcul...
subnet. In this example, our device IP address range is 0 to 255, which means we can identify 256 different IP addresses (0 through 255). But we lose one IP address for the network IP address (the ".0" address) and we lose one for the broadcast IP address (the ".255" address)....

from the HOST part of an IP address in order to divide the larger network into smaller sub-networks called subnets. After subnetting, we end up with NETWORK SUBNET HOST fields. We always reserve an IP address to identify the subnet and another one to identify the broadcast subnet address. ...
Network ID (first address): 192.168.1.0 Broadcast ID(last address): 192.168.1.255 (0 to 255 is 256 integers.) Example 2 192.168.1.16/28 Subnet mask = 255.255.255.240 Hosts: 2^(32-28) = 2^4 = 16 Active hosts = Hosts - 2 = 14 ...
