Changing Comcast IP address

Trying to login remotely to work. IT guy said my Comcast IP address is almost identical to work/office IP address & Xfiinity/comcast would have to change 10.0.0 IP address for it to work.

The concern is not "Home Security Devices And Equipment" help related........... Topic moved here to the proper help section for assistance.

Good Morning, @user_3zitnv! Thank you so much for taking the time to reach out to us here on the Xfinity Forums! I am very sorry to hear about the experience with your connect with work and the IP's being similar. You can attempt to renew and release your IP address following the steps here. Please let us know if that helps with the IP's being similar to one another.

FWIW. Doing that on a computer/device that is connected to a stand-alone router or a combo modem/router gateway device will only serve to renew/change the LAN (private) IP address that is assigned to a computer/device by the router's built-in DHCP server. It will not renew the WAN (public) IP address that is assigned to the router by Comcast's system/DHCP server.
