The following is an example of an IP address in 32-bit binary form and dotted decimal form. Binary IP Address: Decimal IP Address: Binary data is made up of ones and zeros. Ones represent on and zeros represent off. Binary data can be grouped in varying increments, 110 or 1011. In TCP/IP binary data is usually grouped in eight digit groups called a Byte. A Byte, 8 bits, can range from 00000000 to 11111111 creating 256 combinations with decimal values ranging from 0 to 255. IP addressing uses 4 bytes, or 32 bits, to identify both the network and specific device | Cisco Svstems I Lab Binary to Decimal Conversion Objective Learn the process of converting binary values to decimal values. Practice converting binary values to decimal values. Background The following is an example of an IP address in 32-bit binary form and dotted decimal form. Binary IP Address Decimal IP Address Binary data is made up of ones and zeros. Ones represent on and zeros represent off. Binary data can be grouped in varying increments 110 or 1011. In TCP IP binary data is usually grouped in eight digit groups called a Byte. A Byte 8 bits can range from 00000000 to 11111111 creating 256 combinations with decimal values ranging from 0 to 255. IP addressing uses 4 bytes or 32 bits to identify both the network and specific device. The specific device can be a node or host. The example at the beginning of this lab is an example of an IP address in both binary decimal formats. A tool that makes the conversion of binary to decimal values simple is the following table. The first row is created by counting right to left from one to eight for the basic eight bit positions. The tale will work for any size binary value. The value row starts with one and doubles base 2 for each position to the left. Position Value 8 7 6 5 4 3 2 1 128 64 32 16 8 4 2 1 Steps 1. Enter the binary bits in row three. For example 10111001 2. Put the decimal values in row four only for the third row 1s. Technically the row two values are being multiplied by row three. 3. Now just add row four across. Position Value 8 7 6 5 4 3 2 1 128 64 32 16 8 4 2 1 1 0 1 1 1 0 0 1 128 32 16 8 1 185 1 - 2 CCNA 1 Networking Basics v - Lab Copyright 2003 Cisco Systems Inc. 4. Convert the following binary values to decimals a. 1110 __ b. 100110 __ c. 11111111 __ d. 11010011 __ e. 01000001 __ f. 11001110 __ g. .
