Each 44.190.x.0/24 subnet arranges its own BGP advertising, so there isn't just one point. They are spread all over the world.

Note that due to this, the approximate location in IP geolocation databases has to be set for each of the /24 subnets. The default location for 44.0.0.0/8 is San Diego, California, USA. I have set the location for 44.137.0.0/16 to Amsterdam, Netherlands and other country ip coordinators have done similar for their countries. And of course an individual amateur can set a more accurate location for their smaller subnet.
It comes into play for some services that use IP location aware DNS to direct users to a geographically closest (and hopefully this translates to closest in network topology) service. With all the 44.190.0.0/16 networks located in San Diego this of course isn't going to work. Echolink is such a service that users IP geolocation.
You can enter an address from your subnet in lookup services like this: https://www.iplocation.net/
It shows what some of the more important services return for your location. And when clicking on the link for each service it is usually easy to submit location data for a subnet to that service provider.
