Vendor lookup from MAC prefixes

A Go module that provides methods to lookup the Vendor string of an Organizationally Unique Identifier. For Ethernet MACs the OUI is encoded in the first 24 bits.

Vendor lookup is done statically using generated code. Code is generated based in the IEEE registration database.

Usage

package main

import (
	"fmt"
	"net"

	"github.com/endobit/oui"
)

func main() {
	const addr = "00:00:0f:01:02:03"

	// Lookup the vendor of an Ethernet MAC.

	fmt.Println(oui.Vendor(addr))

	// Or, lookup the vendor of a net.HardwareAddr.

	mac, err := net.ParseMAC(addr)
	if err != nil {
		fmt.Println("%q not a mac", addr)
		panic(err)
	}

	fmt.Println(oui.VendorFromMAC(mac))
}

Building

This package uses mage.

Type mage for a list of targets. mage build will regenerate the static OUI data.
