Why Use This Tool?
Some databases, logs, and geo-IP systems store IPv4 addresses as plain integers — 192.168.1.1 becomes 3232235777. This converter handles both directions, and shows the hex and binary forms that firewalls and network classes are built on.
The reverse panel turns a stored decimal back into dotted form, which is how you recover readable addresses from database exports and analytics dumps.
How It Works
- Enter an IPv4 address to see its decimal, hex, and binary forms.
- Or enter a stored decimal to recover the dotted address.
- Use the back-conversion line to verify the round trip.
Frequently Asked Questions
How do I convert an IP address to decimal?
Each octet contributes its value shifted by its position: 192.168.1.1 becomes 3232235777. Enter the IP and the converter shows decimal, hex, and binary at once.
Why do some systems store IPs as decimals?
A 32-bit integer is compact, indexable, and range-comparable — geo-IP databases in particular ship their ranges as integer pairs.
What's the valid decimal range for an IPv4 address?
0 to 4,294,967,295 — every value maps to exactly one address, and the converter rejects anything outside that range.
Tips & Things to Watch
- The binary form shows network classes and masks at a glance.
- Decimal IP in a URL (http://3232235777) still works in browsers — sometimes used to dodge filters.
- Round-trip check is built in: convert back and compare.
