Assigned public ip address missing from maxmind geolocation causing issues with sites that require US location.

Sites that use Maxmind geolocation (and possibly other geolocation tools) send me to the wrong place because they can't determine that I'm in the US.  For example, chatgpt comes up with "Unknown Country" all of a sudden and won't let me login.  "Speedtest by Ookla" sends me to "Accra iNETCOM Ghana" as it can't determine my geolocation.  I did the Maxmind GeoIP demo and put in a bunch of ipv4 addresses that surround mine.  My ip address was the only one that isn't in their database.  I called Xfinity and talked to an agent and she said they couldn't re-assign me a new public ip.  I then talked to a Manager (supposedly) who tried to get me to renew my ip for my ethernet adapter on my laptop (private ip).  They just couldn't understand what I was trying to tell them and got mad when I wouldn't listen to them and try to explain it. 

Can someone at Xfinity get this fixed up at Maxmind asap or get me a new ip?  This is even causing me online banking issues if they use Maxmind.  The public ip assigned is [Edited: "Personal Information"].  Here is just the surrounding ips with my missing address in the middle.

As another data point my router is showing the ip address as [Edited: "Personal Information"]/23.  Shouldn't that be /32?  None of the ip addresses around me show anything under /30.  They are all /30, /31, or /32.

user_d8n8hr We are unable change your IP address unfortunately. You can try using Bridge Mode if you haven't tried that.

I will add that if you are using a Comcast rented gateway device, and you place it into bridge mode as was advised by the employee, you would need to use a stand-alone router connected to the gateway if you want a network / WiFi.

If you are using a router that has a MAC address cloning feature, you can clone a different MAC address into it. This will force a change of your Comcast assigned WAN / public IP address. No guarantees that the new address won't also have incorrect or missing geo-data as it may be from the same block of IP's. YMMV.


And you could also try using a VPN service but it's a crapshoot on what IP / endpoint geolocation will be presented to their servers. Good luck !

I would start by contacting Maxmind.  I wouldn't be too concerned about /##s - your actual IP address doesn't have one of those.  That's just telling you the size of the block that Maxmind thinks it belongs in.  Maxmind lists my current IP as being in a /26 but the other services I use list the same address as in a /17 block. Exact same IP address - but 2 services think it's part of a much larger block than maxmind does.  I think it's kind of strange that maxmind is showing /30, /31, and /32 blocks at all.  This suggests to me that their DB is strangely fragmented.
