The figure below provides binary to decimal number conversion for 135 through 255.įigure 3. Binary to Decimal Number Conversion for 0 to 134 The figure below provides binary to decimal number conversion for 0 through 134.įigure 2. The figure below is an example of an 8-digit binary number.įigure 1. A basic understanding of binary numbering is very helpful if you are going to manage IP addresses in a network because changes in the values of the 32 bits indicate either a different IP network address or IP host address.Ī value in binary is represented by the number (0 or 1) in each position multiplied by the number 2 to the power of the position of the number in sequence, starting with 0 and increasing to 7, working right to left. The 32 bits are divided into four octets (8-bits). Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module. For the latest caveats and feature information, seeīug Search Tool and the release notes for your platform and software release. Your software release may not support all the features documented in this module. This chapter contains information about, and instructions for configuring IPv4 addresses on interfaces that are part of a networking device.Īll further references to IPv4 addresses in this document use only IP in the text, not IPv4.
