IP Address Sorter

Paste multiple IPv4 addresses one per line and it sorts them in numeric order and removes duplicates. All processing happens inside your browser.

Enter the IP list to sort.

How to use

  1. Paste IP addresses one per line.
  2. Select the remove-duplicates and descending options.
  3. Click "Sort" and grab the result with "Copy".

Frequently asked questions

What is the sort based on?

Each IPv4 address is converted to a 32-bit number and sorted by magnitude. Unlike string sorting, 10.0.0.2 comes before 10.0.0.10.

What happens to invalid lines?

Lines that are not in IPv4 format are collected separately below the result and excluded from sorting.

Are the entered values sent to a server?

No. All processing happens only inside your browser, and the values are never sent to or stored on any server.

Practical example and verification criteria

IP Address Sorter: Distinguish IPv4 from IPv6 and select exactly the input the page accepts: an address, CIDR prefix, netmask, or start/end range. Each IPv4 octet must be 0–255 and a prefix must fit the address family's bit range. For host counts, first check the rules for including network and broadcast addresses.

IP Address Sorter: For a quick check, start with 10.0.0.2, 10.0.0.10 → 2,10 as a small input whose result relationship you can verify directly. Confirm that the input summary, units, and options match your intent before applying the tool to real values or a copy of the source; this reduces setup mistakes.

IP Address Sorter: Split the address at binary boundaries and verify that the first and last network addresses, membership result, and total address count agree. Feed a conversion result into the reverse tool to see whether the original is recovered. Remember that a calculation does not change router, VLAN, or firewall settings or guarantee the current route.

IP Address Sorter · Work record: For real work, record the input conditions, selected options, and result together. Do not assume the same state will remain after a refresh or device change. Preserve important results separately using copy, download, a screenshot, or another method the page supports, then reopen them in the target environment.

IP Address Sorter · Error check: If an error or unexpected result appears, reduce the input, run again with default options, and then change one condition at a time. Recording error messages and boundary values helps distinguish format issues, unsupported cases, and browser resource limits, and prevents an empty result from being mistaken for success.

IP Address Sorter · Scope of use: Check the page guidance for browser processing versus server lookup, storage location, and supported scope. Use sensitive source material or secrets only when strictly necessary. High-impact work such as legal, financial, or medical decisions or changes to an operational system requires current authoritative information and a separate verification process.
