Detailed instructions

1. Set the count field to the number of IPv4 addresses you need, from a handful to a large batch.
2. Select an address type — 'public' for internet-facing IPs, 'private' for LAN ranges, or 'any' for unrestricted output.
3. Click the generate button to produce your list of random IPv4 addresses instantly.
4. Copy the output directly into your code, test fixture, config file, or spreadsheet.

Use Cases

• •Seeding a Postgres staging database with thousands of unique fake user IP records
• •Generating mock Apache or Nginx access logs for log-parsing pipeline development
• •Testing firewall ACL rules in Terraform configs against both private and public ranges
• •Populating Jest or Cypress fixtures with varied remote IPs for rate-limiting middleware tests
• •Creating realistic mock client IPs to stress-test geo-IP lookup edge cases and fallback logic

Tips

• →Use the private type when testing Docker or Kubernetes configs — results will stay within realistic LAN subnets like 192.168.x.x.
• →For log simulation, generate a large batch (50+) with 'any' type so your fake log contains a natural mix of client addresses.
• →Combine public addresses with a real geo-IP API call during testing to exercise your app's location fallback paths.
• →When seeding a SQL database, generate your IPs here, paste into a spreadsheet, then use a VLOOKUP or script to pair each IP with a fake user row.
• →If your firewall ACL test needs to cover all three private blocks, run the generator three times with 'private' selected and verify each block appears in results.
• →Avoid hardcoding a single fake IP like 192.168.1.1 across all test cases — repeated IPs can mask bugs that only appear with unique addresses.
