About IP to Number Conversion
Convert IP addresses between dotted-decimal notation (e.g., 192.168.1.1) and numeric formats (decimal, hexadecimal, binary). Useful for network programming and database storage.
How to Use
Enter an IP address to see its numeric equivalents, or enter a decimal/hex/binary number to convert back to an IP address. All conversions update in real time.
Conversion Formats
Decimal: a single 32-bit unsigned integer. Hexadecimal: the same value in base 16. Binary: the 32-bit binary representation. Each octet corresponds to 8 bits.
▶Why convert IP to a number?
Numeric IP representation is more efficient for database storage and comparison. It enables range queries and subnet calculations using simple arithmetic.
▶Does this support IPv6?
This tool currently supports IPv4 addresses only. IPv6 uses 128-bit addresses which require a different conversion approach.
▶What is the range of valid decimal values?
IPv4 addresses map to decimal values from 0 (0.0.0.0) to 4,294,967,295 (255.255.255.255).
