My IP address is showing the wrong location after "planned maintenance."

The maintenance was not further explained, and I can't get any details by calling Comcast's horrendous support number.

The outage occurred overnight and lasted about eight hours. It was planned, but not communicated to us until after we called to find out what happened.

Now my IP address is geolocating to two cities away from where we actually live and 60 miles from where we are. 

Prior to this maintenance, the geolocation was precisely atop our house.

Also, my bandwidth seems to be about 50 percent of what it was before (although this may because speedtest is testing in the foreign city, not nearby).

What happened?

Why did it happen?

And how do I get it fixed?

You received a new / different WAN (public) IP address assignment to your connection from their DHCP server / IP address pool, and the rDNS / geolocation data that is associated with it is now incorrect for you as it previously belonged to someone else who lived in that other area. 


Comcast shuffles blocks of IP addresses around the country all the time. And after doing local plant maintenance / upgrades. ISP's don't correct this. A third-party service does. Unfortunately, this is typically a back-burner thing to get corrected. The only thing that you can do is to report it. You can try this;

https://support.google.com/websearch/contact/ip/ 


https://ipinfo.io/corrections 


https://www.whatismyip.com/ip-address-geolocation-incorrect/ 


https://ipregistry.co/data-corrections 


Wait for the geolocation provider to approve your request. If your request is approved, the amount of time it takes to see the correction varies by provider. The average is two weeks to a month or more.


You can also try this;


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 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.

Thank you for the detailed response.

Perhaps I've never noticed before, but this seems to be the first time it's ever happened.

FYI.

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.
