How to change your IP address
Reviewed 10 September 2026 · 5-minute read
First decide whether you need to change a private address inside your network or the public address websites see. The device or router controls the former; the ISP, workplace or VPN usually controls the latter.
Change a private address
Reconnect to the network or renew the DHCP lease through the operating system. A router reservation or manual configuration can keep a chosen local address, but it must match the subnet and avoid conflicts.
Change the public address
- Record the current result on this site.
- Reconnect the router or ask the provider about reassignment; a dynamic plan does not guarantee an immediate change.
- Alternatively, connect to a trusted VPN and reload. Websites should then normally receive the VPN exit address.
Limits and cautions
A VPN changes the path and visible source address but shifts trust to the VPN provider. Carrier-grade NAT can mean the public address is shared and not under your router's control.
