Desktop Pinger is a very simple and small tool, totally free, that does not even require installation.
From Desktop Pinger you can make all kinds of pings to know if a team (or several) is well connected to the Internet, that is, if it has good online access and, therefore, manages to reach the different IPs you indicate without interruptions.
In this way, with Desktop Pinger you will be able to test the access to all the IPs you want (both from other computers connected in the same local network as the access to Internet web pages), to check the response time of each of these accesses, and thus verify that everything works perfectly.
