Hi dannyocch,
IP addresses are assigned automatically through our Dynamic Host Configuration Protocol (DHCP) servers. The lease for the IP address assigned to your equipment typically lasts 24 hours, but it can automatically renew anywhere between 12-24 hours after the lease is issued. When you reboot your modem, the Dynamic Host Configuration Protocol (DHCP) server tries to set up your connection using same parameters that were previously set for your modem. If the same IP address is available, the DHCP server simply refreshes the lease; otherwise, you will be assigned a new IP address based on the pool of available addresses. In the network settings of your device, verify that your TCP/IP settings are configured dynamically, not statically, with no assigned DNS servers. Since our IP addresses are assigned dynamically, there is no method for changing an IP address. If you unplug the device connected to your modem for more than 12 hours, there is a possibility that it will be issued a new IP address. This is not a guaranteed method to obtain a new IP address, however, we do not have a way to force our system to change the IP address for modems connected to our system.
Hope this helps.
