Batch extract valid IPv4 addresses from logs, code, or any text. Includes built-in counting statistics.
Enter text to start extraction
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Paste a block of text to collect IPv4-like values in the dotted-decimal form, such as 192.0.2.18. The extractor scans the text for four groups of one to three digits separated by periods, then keeps a candidate only when each group is between 0 and 255. Results appear as a line-by-line list that you can copy.
IPv4 addresses are 32-bit values commonly written as four octets. This tool uses that familiar dotted form as a text-matching pattern; it is not a network lookup, reachability test, or full protocol parser.
By default, duplicate strings are removed, and the first occurrence order is retained. Turn off duplicate removal when you need to see each matching occurrence. The displayed count then reflects the resulting list. Similar numeric spellings are compared as text: 1.2.3.4 and 001.002.003.004 remain distinct entries.
The copy action places the displayed addresses on separate lines. It does not annotate them with source line numbers or explain where in the original text each match occurred.
Use logs, configuration text, notes, or another text block. The input is scanned as text; the tool does not open a file.
Leave duplicate removal on for a unique list, or switch it off to preserve repeated occurrences.
Check the results and count, then copy the list. Confirm any candidate against its original context before acting on it.
| Text fragment | Result | Reason |
|---|---|---|
host=192.0.2.18 | Match | Four decimal groups; each is within range |
300.2.3.4 | Skipped | One group is greater than 255 |
001.002.003.004 | Match as written | Leading zeros are preserved; values pass the range check |
host_192.0.2.18 | May not match | An underscore is a word character next to the digits |
Paste a selected log section to collect dotted IPv4 candidates for a separate manual review.
Extract candidate addresses from notes, then keep repeats or reduce the list to first-seen values.
Copy extracted strings into a network inventory or diagnostic workflow that can validate their role and status.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Paste the portion of a log, note, or configuration you want to inspect.
Choose whether repeated occurrences should be collapsed to their first appearance or kept in the output.
Review the values and count, then copy the list with one address per line.
Use cases
See how the tool fits into real work and everyday tasks.
Collect candidate IPv4 strings from pasted logs before you investigate individual entries.
Use duplicate removal for a compact list or preserve occurrences when frequency in the source matters.
Notes
Review scope, result limitations, and important precautions before use.
