Tech Chat | Understanding LAN, Public, and Static IPs in CORS Setup
For high-precision CORS networks, IP addresses are critical for communication between devices and network. From configuring your SV100 CORS receiver on-site with a LAN IP to using a Public IP for remote access, knowing the differences between LAN, Public, and Static IPs is helpful. This blog explains how each type of IP plays a role in managing and maintaining a stable CORS system.
What is an IP Address?
An IP address (Internet Protocol Address) is a unique identifier that helps locate devices (computers, servers, routers, etc.) on the Internet or within a network. It's composed of numbers and dots that allow devices to communicate.
For instance, when configuring the SV100 CORS receiver on-site, you can connect to the device's Wi-Fi and access the web configuration interface through its LAN IP (Local Area Network IP). On the other hand, when using SV100 as a CORS station, a Public IP is needed for rovers outside the local network to connect and receive differential data. A Static IP is recommended to ensure a stable, continuous connection, preventing interruptions in long-term use.
Types of IP Addresses
1. LAN IP (Local Area Network IP)
A LAN IP is used within a local network, typically for connecting devices in the same geographical area, such as within an office or a construction site. For example, if you are configuring your SV100 CORS receiver on-site, you can use a LAN IP to connect locally through the network's gateway (e.g., 192.168.2.1). LAN IPs are essential for device-to-device communication within the same network, but they don't provide access to external devices outside the network.
- Example of LAN IPs: 192.168.2.4, 192.168.2.5, 192.168.2.6.
2. Public IP
A Public IP allows devices to communicate over large distances, spanning regions or even countries. This is crucial when you need remote access to a CORS station from a different location or when rovers located outside the LAN need to connect to the CORS server for differential data. When using SV100 as a base station, a public IP ensures that rovers outside the local network can receive corrections.
- Example of Public IP: 203.102.20.12.
3. Static IP
A Static IP is a permanent address assigned to a device or network, ensuring consistent and reliable access. For CORS server setups, using a static IP is recommended for stable long-term connections. A dynamic IP address might change over time, causing disruptions in data transmission. However, static IPs are more costly and typically used for dedicated servers or systems requiring uninterrupted access.
