# URZ: MAC Address Retrieval Guide

This source provides technical instructions for users of the Universität Greifswald network on how to identify the MAC address of their wired end-devices. This information is a prerequisite for the [[device-registration]] process to gain network access.

## Key Information
- **Purpose**: To obtain the physical address (MAC address) of a network adapter for wired device registration.
- **MAC Address Format**: Six blocks of two hexadecimal values, separated by colons (`:`) or hyphens (`-`). Example: `XX:XX:XX:XX:XX:XX` or `XX-XX-XX-XX-XX-XX`.
- **Scope**: Specifically targets **wired** (drahtgebunden) connections.

## Retrieval Methods by Platform
- **Windows**: 
    - Command line: `cmd` $\rightarrow$ `getmac /v` (identify the "Ethernet" entry).
    - Tool: A provided VB-Script is available for easier extraction.
- **Linux**: 
    - Command line: `ifconfig` (look for "Hardware Adresse").
- **macOS**: 
    - Path: System Settings $\rightarrow$ Network $\rightarrow$ [Select Adapter] $\rightarrow$ Advanced/More Options $\rightarrow$ Hardware tab.
- **ZeroClient**: 
    - Physical location: Found on a sticker on the underside of the device.

## Support
Technical issues regarding Campus-IT are handled by the [[universitatsrechenzentrum-urz]] via:
- **Ticket System**: Hosted on [[groupware]].
- **Hotline**: Extension **1420**.
