This tool is useful for determining the status of the network and various foreign hosts, tracking and isolating hardware and software problems, and testing, measuring, and managing networks. Want to stay online while you chatting, downloading etc. without your phone going in power safe mode, which will disconnect your network? No problem, just hit Follow key and you are set to go!

Changes:

– added ability to choose server from settings tab. The servers are saved in “WhoIsServers.txt” file, which can be modified easily if needed. The default server is “whois-servers.net”, which have to be queried with domain extension, beside others servers from this list, which have to be queried without it. Will change this when I have more time.
– added “Connect” in Tools menu, which will check your internet connection and will try to establish it, if not exist.
