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.  Country 2 Ip Ranges  ||  Subnet Mask ||  IP Ranges Generator  ||  IP Subnet Mask

IP Address Calculator calculates and find IP Subnet Mask on basis from given IP Address. If second netmask for subnet is given then you will find IP subnet mask and get the results displayed in binary values.

1. blue - IP Address (alias "dotted quad" = number consist of four parts seperated by dot e.g. 127.0.0.1)
2. green - subnet bits (Classes)
4. magenta - classbits
5. yellow - binary
6. black - standard

To find IP subnet mask from given IP ranges please check out our IP Subnet Mask Calculator
Note:
• To prevent server resources we have limited number of Subnets to 100.
• We do not check on the correctness of the IP or subnet mask combination.
• First bits (see green bits color) will decide your network class and private network IP addresses (according to RFC 1918) are remarked.
