Each time you restart your router, your Internet Service Provider (ISP) may assign a new dynamic IP address using DHCP.

Why does my public IP address change every time I restart my router?

Each time you restart your router, your Internet Service Provider (ISP) may assign a new dynamic IP address using DHCP.
Most home internet plans don’t include a static IP by default.

🔁 Common reasons:

• Your ISP uses dynamic IP pools
• Your router doesn’t request the same IP
• The DHCP lease resets on reboot

✅ Want to keep the same IP?

• Ask your ISP for a static IP
• Or use Dynamic DNS
