Random IP Address Generator

Random IPv4 addresses in dotted-decimal form (192.0.2.45). Set Count from 1 to 200; the output panel fills with that many addresses, one per line. Each octet is uniform over 0-255, so reserved and private ranges show up as often as any other. For MAC addresses see the random MAC generator.

Plausible IPv4 fixtures for tests and logs

An IPv4 address is four octets of 8 bits each (0 to 255), separated by dots. The generator draws each octet independently and uniformly, then joins them with dots. Output is one address per line, ready to paste into a log fixture, a firewall test plan, or a database seed.

There is no filtering. Reserved blocks (0.0.0.0/8, 10.0.0.0/8, 127.0.0.0/8, 192.168.0.0/16, 224.0.0.0/4, etc.) appear with their natural probability, which means a fraction of the output will land in private or non-routable ranges. If you need only public IPs, post-filter the result.

Use this for synthetic fixtures rather than for real-world targets. To generate plausible MAC addresses see the random MAC generator; for hex strings of any length see the random string generator.

How to use random ip address generator

  1. 1Open the tool. The input panel can be left empty.
  2. 2Set Count in the option panel (default 10, maximum 200).
  3. 3The output panel fills with that many IPv4 addresses, one per line.
  4. 4Click Copy to grab the list.
  5. 5Filter out reserved ranges by hand if you need only public IPs.

What this tool actually does

IPv4 dotted-decimal

Output is the standard A.B.C.D form, where each part is a decimal number from 0 to 255. No padding, no hex.

Each octet is independent and uniform

Each of the four octets is drawn independently from the uniform distribution on 0-255. There is no de-duplication or correlation between octets.

No filtering of reserved ranges

Private (10/8, 192.168/16), loopback (127/8), multicast (224/4), and other reserved blocks appear at their natural probability. Filter out blocks you do not want with a script after copying.

Bulk count up to 200

Count ranges from 1 to 200. Each address is independent; duplicates are very unlikely in any reasonably small batch.

Browser-only

Generated via Math.random() on each octet and joined with dots. No upload.

Worked example

Five IPv4 addresses. The first three are in the documentation prefixes (TEST-NET-1/2/3); the last two land in private ranges. The generator does not filter, so reserved blocks appear at their natural probability.

FAQ

Will I get IPv6 addresses?
Not in this version. The generator emits IPv4 dotted-decimal only. For random IPv6 you would need a hex generator and manual formatting.
Are private and reserved addresses excluded?
No. The generator draws each octet uniformly with no filtering. Roughly 7% of addresses land in private blocks (10/8, 172.16/12, 192.168/16) and another small fraction land in loopback or multicast. Filter them out with a script if you need only public IPs.
Are these real IPs that point to a real server?
They are syntactically valid IPv4 addresses; some will route to live hosts, others to nothing. Use them as fixtures, not as production targets.
Can I bias the output toward a specific subnet?
Not from the option panel. The simplest workaround is to take the last octet from the generator and prepend a fixed prefix using the find and replace tool.
Is the output sent anywhere?
No. The addresses are computed in your browser. Nothing leaves the page.
