To convert an IP dotted-quad address to binary, take each decimal number of the dotted-quad and look up the binary equivalent in the Binary Conversion Table below. You will have a 32-bit binary number as the result.
To convert a binary number to an IP dotted-quad, take groups of 8 bits, look them up in the table below, and write down the equivalent decimal number. The first 8 bits represent the first decimal number of the dotted quad, the second 8 bits represent the second decimal number of the dotted quad, the third 8 bits represent the third decimal number of the dotted quad and the final 8 bits represent the last decimal number of the dotted quad.
Example of dotted-quad to binary conversion:
Dotted Quad | 192. | 9. | 200. | 1 |
Binary | 1100 0000 | 0000 1001 | 1100 1000 | 0000 0001 |
Example of binary to dotted-quad conversion:
