SmartWhois is a network information tool that provides details about IP addresses, domain names, and hosts. With information retrieved from over 100 servers, it delivers comprehensive updates in real-time.

One of the great features of SmartWhois is that it can be set up to have functionality behind a firewall, which can be achieved by using HTTP/HTTPS proxy servers, and it supports different SOCKS versions. Unlike traditional Whois utilities, SmartWhois can obtain information about any computer worldwide, skillfully querying the proper database and providing corresponding records in mere seconds.
SmartWhois has the ability to access data from over 100 servers worldwide, making it highly effective and reliable. Users can also create an archive file, where information they have obtained is saved, and in subsequent launches of the program, and they can load this archive and add more information to it, ultimately creating and sustaining their database of IP addresses and host names. The results obtained from queries may be saved in several formats, which include HTML, text, XML, and XLS.
Moreover, SmartWhois has an excellent feature that allows users to load a list of IP addresses as a text file, and this list can be processed using the program. Additionally, SmartWhois is capable of caching query results, thereby reducing the duration required to query an address; if the data is in the cache file, it is displayed instantly, requiring no further connections in subsequent usage of the whois servers.
In conclusion, SmartWhois is an extremely valuable network information utility with multiple features that guarantee it will be an essential tool of networking professionals.
