Получение информации об IP-адресе, домене

Network Query Tool (NQT) это комплексное решение для получения информации о домене или IP адресе. Вместо ручного запуска различных unix команд или посещения многих сайтов для исследования хоста, просто загрузите Network Query Tool и введите имя хоста или IP адрес. NQT сделает следующее: обратный поиск, запрос DNS (dig), whois (владелец домена), whois (владелец IP), проверку порта, ping и traceroute.


Host Information Host Connectivity

Resolve/Reverse Lookup
Get DNS Records
Whois (Web)
Whois (IP owner)

 Check port:
Ping host
Traceroute to host
