Ethernet and IP networks work together but serve different purposes in networking.
Key Differences
| Aspect | Ethernet | IP Network |
|---|---|---|
| OSI Layer | Layer 1 & 2 (Physical + Data Link) | Layer 3 (Network) |
| Purpose | Physical connection & local delivery | Routing between networks |
| Addressing | MAC addresses (hardware) | IP addresses (logical) |
| Data Unit | Frames | Packets |
| Scope | Local network (LAN) | Multiple networks (WAN/Internet) |
Ethernet: The Cat6 cable running through your CRCA perforated panels and marshalling cabinets
IP Network: The addressing system that lets PLCs, sensors, and DCS talk across your plant
