Numbering system
An IP address uniquely identifies every host on a network.
TCP/IP looks at IP addresses in binary form, but as humans, we prefer to see
IP addresses in decimal form. Because the protocol is seeing only binary, working
with IP addresses makes more sense when you also look at the IP addresses in
binary.
- binary
The base-2 number system that computers
use to represent data. It consists of
only two digits: 0 and 1.
- decimal
The base-10 number system that people
use to represent data. It consists of 10
digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Converting Binary Numbers to Decimal
Converting binary to decimal and decimal to binary is an important skil.
Network administrator will know the exact values that TCP/IP uses.
Converting
- binary number 0001 - The decimal equation for the conversion is 0 + 0 + 0 + 1 = 1 decimal
- binary number 0110 - The decimal equation for the conversion is 0 + 4 + 2 + 0 = 6 decimal
- binary number 1110 - The decimal equation for the conversion is 8 + 4 + 2 + 0 = 14 decimal
- binary number 1111 - The decimal equation for the conversion is 8 + 4 + 2 + 1 = 15 decimal
Each of these columns represents a bit (binary digit). The greatest decimal number
that can be represented by number 4 bits is 15.

IP Address Mask Subnet Calculator - Subnetting
IP Address Calculator calculates on basis from given Ip Address
and netmask broadcast, network, host range, Cisko wildcard mask.
if second netmask for subnet/supernet is given then you will get
the results for it display in binary values.
Color legend:
-
blue - IP Address (alias "dotted quad" = number consist of four parts
seperated by dot e.g. 127.0.0.1)
-
green - subnet bits (Classes)
-
red - netmask
-
magenta - classbits
-
yellow - binary
-
black - standard
|
Note:
- To prevent server resources we have limited number of Subnets to 100.
- We do not check on the correctness of the IP or netmask combination.
- First bits (see green bits color) will decide your network class and private network ip addresses (according to RFC 1918) are remarked.
Special thanks to Krischan Jodies for this script.
