I just started my XFinity service and I purchased an SBG8300 for both my modem and router. I am not able to connect to any websites besides google, youtube, instagram etc. I realized that I am only able to connect to websites with IPv6. When I log into my modem, I see that the WAN IPv4 is 0.0.0.0 and the WAN IPv6 is something.
I believe I am not receiving an IPv4 and so I cannot use many websites. If I check using whatismyip, I don’t get any result for IPv4, but I do for IPv6. If I use the command prompt to ping google, it works using ping -6 but not using ping-4.
Is there anything on the modem end that could be done to further troubleshoot or is this an issue with my ISP?
