Public IP vs. private IP
Private IPs (like 192.168.x.x) are used inside your local network. Your public IP is used on the internet. NAT lets multiple devices share one public IP.
IPv4 vs. IPv6 (simple explanation)
IPv4 uses 32‑bit addresses and is running out of space. IPv6 uses 128‑bit addresses, supports far more devices, and improves routing for modern networks.
Why your IP may change
Many ISPs assign dynamic IPs. Rebooting your modem, changing networks, or moving between mobile towers can give you a different public IP.
Does a VPN hide my IP?
A VPN usually changes the IP that websites see to the VPN server’s IP. Your ISP can still see your encrypted VPN connection, but not the websites you visit.
How to find your IP on Windows, macOS, and Linux
On Windows, you can use ipconfig to see local IPs. On macOS/Linux, use ifconfig or ip. This website shows your public IP seen by servers on the internet.
What is a proxy, and how is it different from a VPN?
A proxy forwards your traffic for specific apps or protocols, while a VPN creates an encrypted tunnel for more of your device’s traffic. Both can change the public IP that websites see.
IP address privacy tips
Avoid sharing your IP publicly, keep your router updated, use strong Wi‑Fi passwords, and consider a reputable VPN on untrusted networks. Remember that IPs can be used for rough location estimates.
