Can I change my IP address by plugging and unplugging the router when using a fiber optic connection

Unplugging your router may change your IP address if you have a dynamic IP, but the result depends on your ISP's policies and the duration of disconnection.How It WorksWhen you use a fiber optic connection, your ISP assigns your router a public IP address. If your connection uses a dynamic IP, this address can change over time. Unplugging your router disconnects it from the ISP's network, which may release the current IP. When you reconnect, the ISP may assign a new IP from its pool, but this is not guaranteed and depends on how the ISP manages DHCP leases and IP allocation .Factors Affecting IP ChangeType of IP Address:Dynamic IP: More likely to change after unplugging.Static IP: Assigned permanently by the ISP and cannot be changed by unplugging .ISP Policies: Some ISPs immediately assign a new IP upon reconnection, while others may keep the same IP for hours, days, or even months .Duration of Disconnection: Leaving the router unplugged for a longer period (typically 5–30 minutes or more) increases the chance of receiving a new IP, as the DHCP lease may expire .MAC Address Binding: Some ISPs tie the IP to your router's MAC address. In such cases, unplugging alone may not change the IP. Using MAC address cloning can force a new IP assignment .Alternative MethodsRouter Settings: You can manually release and renew the IP through your router's firmware or network settings .Contacting ISP: Requesting a new IP directly from your ISP ensures a change.VPN Services: Mask your public IP without changing the ISP-assigned address.SummaryUnplugging a fiber optic router can sometimes change your IP, but success depends on whether your IP is dynamic, your ISP's DHCP policies, and how long the router is disconnected. For a more reliable change, consider using router settings, MAC address cloning, or contacting your ISP .
