HotWhoIs is a convenient and easy-to-use application for sending queries on IP addresses and domain names to whois servers and examining the results. Using HotWhoIs, you can obtain all available information related to a given IP address or domain name. You can retrieve information about the organization or the internet service provider (ISP) that owns the IP address, including information about the country, state, city, address, contact phone numbers and e-mail addresses. HotWhoIs supports the new data format used by arin.net and forwards queries on the Latin America IP addresses to the lanic.net server. HotWhoIs uses 88 whois servers all around the world to obtain information on 120 domain zones. The program can also query whois servers with plain web POST requests and display the results in the regular format. Currently, such requests can be performed for Argentinean (.ar) domain names. Moreover, the program in most cases can determine the name and version of the remote web server. It can also ping remote hosts so you can check its availability. The utility also supports SOCKS 4 and 5 proxy servers and can perform whois requests from a network connected to Internet via these kinds of proxies.
