Regular expressions (regex) are highly effective for validating standardized data formats like MAC addresses. In network configuration and management applications, ensuring the correct format of MAC addresses is essential. A common regex pattern for MAC address validation is ^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})$, which matches the typical MAC address format.

MAC Address Regex

A MAC address typically consists of six groups of two hexadecimal digits, separated by colons or hyphens.

The MAC Address Regex Pattern

The regex pattern for a standard MAC address is:


This pattern ensures that the MAC address follows the correct hexadecimal format and separators.

How to Validate MAC Addresses Using Regex in Go?

Validating a MAC address in Go with regex involves:

  1. Define the regex pattern for a valid MAC address.

  2. Compile the regex using the regexp package in Go.

  3. Validate the MAC address strings with the compiled regex.

package main

import (

func isValidMACAddress(mac string) bool {
    // Define the regex pattern
    var macRegex = regexp.MustCompile(`^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})$`)
    return macRegex.MatchString(mac)

func main() {
    testMAC := "01:23:45:67:89:AB"
    fmt.Printf("Is '%s' a valid MAC address? %t\n", testMAC, isValidMACAddress(testMAC))

Uses of MAC Address Regex Validation

MAC address regex validation is crucial for:

  1. Network Configuration: Ensuring valid MAC addresses in network setup and management.

  2. Device Identification: Accurately identifying devices in a network based on their MAC addresses.

  3. Data Integrity: Maintaining accurate and standardized MAC address records.
