randmac
a random 12-digit mac address generator
Decision gist · record as of 2026-08-14
Yes, if you need a simple, dependency-free MAC address generator for testing or development. The low install friction and permissive license make it a low-risk addition. However, the abandoned maintenance status and Alpha classification mean it's best suited for non-critical tooling; do not rely on it for production systems. Verify LAA format correctness for your specific use case before deploying.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >3.2
- Low install friction with no runtime dependencies.
- Package is abandoned (last release 2020-09-13, last commit 2023-05-25) and classified as Alpha, so expect no active maintenance or bug fixes.

What it is and what it does
randmac is a lightweight utility for generating random MAC addresses in multiple formats. It can produce either full 12-digit addresses or preserve the manufacturer (OUI) portion while randomizing the NIC-specific portion. The package supports five common MAC address formats: colon-separated (MM:MM:MM:SS:SS:SS), hyphen-separated (MM-MM-MM-SS-SS-SS), dot-separated (MM.MM.MM.SS.SS.SS), Cisco format (MMMM.MMSS.SSSS), and unformatted (MMMMMMSSSSSS).
The main use case is generating test or mock MAC addresses for network testing, device simulation, or security research. It includes a command-line interface for quick generation and a Python API for programmatic use. The optional LAA (locally administrated address) mode ensures generated addresses are marked as locally administered by constraining the first hex digit to x2, x6, xA, or xE, which is useful when you need addresses that won't collide with real hardware vendors.
Use it for
- Generate mock MAC addresses for network testing and device simulation scenarios
- Create test data for network monitoring or DHCP server testing
- Randomize NIC portions while preserving a specific OUI for vendor-specific testing
- Generate LAA-compliant addresses for local network administration and testing
- Quick command-line MAC address generation without writing code
