# Data Network Infrastructure

**Data Network Infrastructure** (Datennetztechnische Infrastruktur) refers to the collective physical and logical systems, hardware, and configurations that enable data transport, communication, and connectivity across the Universität Greifswald campus.

At the university, this infrastructure is planned, administered, and centrally managed by the [[netze-und-kommunikation]] department.

## Key Components

The infrastructure encompasses several critical network services and hardware elements:

### Physical and Wireless Connectivity
- **Network & WLAN / Physical Networking**: This includes the physical cabling, hardware (such as switches and routers) that form the backbone of the campus network, and wireless access points providing connectivity and mobility for users.

### Addressing and Naming
- **DNS (Domain Name System)**: The system used to resolve human-readable hostnames into IP addresses.
- **DHCP (Dynamic Host Configuration Protocol)**: The service that automatically assigns IP addresses to devices connecting to the network.

### Remote Connectivity
- **Secure Access**: The implementation of **VPN** tunnels to extend the internal network to remote users.
