The website used to be on a server with the IP address of ip-A. Recently it was migrated to a new server ip-B. DNS settings have been updated.
Now most visitors are directed to ip-B correctly.
However, still a few visitors are accessing ip-A, probably because their DNS servers are not refreshed. The domain name is still pointing to ip-A on those DNS servers.
My questions is, is it possible to "force-update" all DNS servers that contain the domain name of this website?
