The two things I attempted to do with ManageEnginePingTool were not great. Just resolving a host, ManageEnginePingTool doesn't do anything after I type in the name and hit enter, so I hit the big plus sign, no response. 5 seconds later, it finally responds with the IP, but ManageEnginePingTool just appears frozen prior to that.
The other thing I wanted to do was a reverse DNS lookup, an extremely common and basic ping feature that one would expect to exist in any Ping tool. Alas, there is not, so you get 1 star. Do better.
