All sorting happens locally in your browser — no data is ever sent to a server.

Why Plain Text Sort Gets IPs Wrong

Sorting IP addresses as plain text strings produces the wrong order — alphabetically, "10.0.0.10" comes before "10.0.0.2" because '1' sorts before '2' at that character position. This tool converts each address to its true 32-bit numeric value before sorting, so "10.0.0.2" correctly comes first.

Key Takeaways

True Numeric Order: Sorts by the actual 32-bit address value, not string comparison.
Optional Deduplication: Remove duplicate entries automatically, or keep them by unchecking the option.
Client-Side Only: All sorting happens locally in your browser — no data is ever sent to a server.
