How to Convert Netmask to IP

Network addresses can be complicated.

A netmask is a set of binary values added to a transit communications interface profiles (TCIP) address to show which network the Internet protocol (IP) address is part of. When viewing a netmask value, only part of the binary segment is usable by a router. Converting a netmask value into an TCIP address is not too difficult. By following the steps for converting a dummy netmask value, it is possible to show how to covert a netmask value into a TCIP addresses.

Things You'll Need

• Netmask binary address
• Online IP address calculator (http://jodies.de/ipcalc)

Instructions

1. Launch a Web browser. Enter "http://www.subnetmask.info/" into the address field. Click on the "Enter" key.

2. Enter the netmask value "11111111 11111111 11111111 11111111" into the netmask value fields.

3. Right-click on the "calculate" button next to the TCIP address line. The TCIP result will be "255.255.255.255".

Tips & Warnings

• Converting a netmask value to a decimal IP address can require a great deal of manual calculations. A calculator that handles large binary numbers is recommended.
