IP Address Sorter

Sort IPs the way they actually order

Sorting IP addresses as plain text puts 10.0.0.2 after 10.0.0.19, because "1" comes before "2" character by character. That alphabetical order is almost never what you want. This tool sorts a list of IPv4 addresses in true numeric order, so 10.0.0.2 comes before 10.0.0.19 as it should, ascending or descending.

Why text sorting gets it wrong

An IP address is four numbers, and each should be compared as a number, not as text. A text sort compares character by character, so it ranks 100 before 19 because "1" then "0" sorts before "1" then "9". Sorting numerically octet by octet fixes this, which is the only way a list of addresses comes out in the order a human expects and a network treats them.

Cleaner lists, fewer duplicates

Beyond ordering, the tool can remove duplicate addresses as it sorts, which is handy when the list came from concatenated logs or exports. The result is a clean, correctly ordered set you can scan or paste onward. The sorting runs in your browser, so an internal list of addresses is not uploaded.
