Have you ever heard of the WAN IP address? If you're not a tech enthusiast, this term may be unfamiliar to you. However, it is an essential part of internet networking, and understanding it could help you troubleshoot some issues with your internet connection.
What is a WAN IP address?
A WAN (Wide Area Network) IP address is a unique identifier assigned to your device by your internet service provider (ISP). This address is distinct from your local area network (LAN) IP address and is used to communicate with devices outside your LAN network.
Why is it important?
Every device on the internet must have an IP address to communicate with other devices. Your WAN IP address is necessary for devices outside your network, such as servers or other computers, to communicate with your network. It is essential for internet browsing, online gaming, and video conferencing, among other online activities.
How is it different from a LAN IP address?
Your LAN IP address is used for devices connected to your local network. It is assigned by your router and can be used for internal communication between devices on the same network. Your WAN IP address, on the other hand, is used for external communication, and it is assigned by your ISP.
Can it be changed?
Yes, your WAN IP address can be changed, but it's not easy to do so. Your ISP must assign you a new IP address, which usually happens when you restart your modem or router. It's important to note that changing your IP address may affect some online services that rely on it, such as remote access, VoIP services, and virtual private networks (VPNs).
Understanding your WAN IP address can help you diagnose network problems and ensure a smooth online experience. With this knowledge, you can communicate effectively with your ISP and IT professionals when necessary.
