Random MAC Addresses Generator

Generate random MAC addresses for testing — up to 2000 at once

Quickly create lists of dummy Media Access Control (MAC) addresses for network simulation, QA and security testing. The tool produces a plain list you can copy to clipboard for immediate use in scripts, test data or device labs.

How to use

• Open the tool from the menu: Generate → MACs.
• Adjust any available parameters in the toolbar (count, etc.), then click Generate MACs.
• Use the page Copy control to copy the generated list to clipboard. (The tool supports clipboard export only — no direct file download.)
• Paste the copied list into your test scripts, CSV, or device configuration files.
• 

Common use cases

• Network simulation: populate virtual switches, emulators and testbeds with unique-looking device addresses.
• Security testing: exercise MAC-based filters, access controls and detection rules with synthetic device identifiers.
• Software & hardware QA: feed monitoring and provisioning systems with dozens or thousands of addresses for load and validation tests.

Examples (copy-ready)

Sample MAC addresses (colon-separated):

00:1a:2b:3c:4d:5e
a4:5b:6c:7d:8e:9f
de:ad:be:ef:00:01

Use the copy control to paste these or your generated list directly into tools and scripts.

Tips & edge cases

• Bulk limit: the generator can produce up to 2000 addresses in one request. For larger datasets, generate multiple batches and combine them locally.
• Uniqueness: generated addresses are random. If strict uniqueness is required, verify the list locally after copying (for example, using a simple de-duplication step in your editor or script).
• Device-specific needs: some devices expect certain OUI/vendor prefixes. The generator creates generic test MACs — if you need vendor-specific OUIs, add them to your list after generation.
• Formatting: if you need a different separator or case, transform the copied list with a local text tool (see Related tools below).
• Automation: paste copied MACs into your deployment scripts or CSV templates for bulk provisioning or simulation runs.

Safety & acceptable use

• Use generated MACs for testing, simulation and development only. Do not use them to impersonate devices, bypass network controls or for any illegal activity.
• Generated addresses are synthetic and intended to populate labs and test environments — treat them as fixture data, not real hardware identifiers.

Combine MAC lists with other PicoToolkit generators to build realistic test datasets:

• Lorem Ipsum for dummy content in documentation or UIs
• Random Numbers for numerical test fields
• IP Generator for paired IP + MAC test data
• Realistic Names Generator for associating devices with identities
• String Generator for arbitrary test values
• Email Generator for simulated user accounts
• Text helpers: Remove Duplicates, Convert Newline to Comma or CSV to JSON to reformat copied lists for tooling and imports.

Quick troubleshooting

• If copied list contains duplicates, run a local de-duplication (tools like "Remove Duplicates" can help).
• If a target system rejects addresses, confirm that the format and any required vendor OUI match the device expectations.
• For repeated test runs, label batches or append an identifier to avoid accidental reuse of the same data in production-like environments.
