IP to Numeric Address Conversion Tool

This tool enables fast bi-directional conversion of IP addresses to integer numbers, using the standardip2long andlong2ip algorithms to ensure that the results are consistent with the built-in functions of programming languages (e.g. PHP, Python).

Functionality

IP to Numbers： Converts IPv4 addresses (e.g. 66.102.7.147) to 32-bit unsigned integers (e.g. 1113982867).
Numbers to IP： Reduces a decimal number to the standard dotted decimal IP format.

Application Scenarios

• Database storage optimisation: replace IP strings with integer numbers to save space.
• Network development and debugging: directly access the target server through the numeric address.
• Data analysis: Quickly compare IP segment attribution ranges.

Technical principle

Conversion formula: The first part x 256³ + The second part x 256² + The third part x 256 + The fourth part
Example: 66.102.7.147 = 66×16777216 + 102×65536 + 7×256 + 147 = 1113982867
