HotWhois is an easy-to-use IP Lookup application for sending queries on IP addresses and domain names to whois servers and examining the results. You can retrieve IP Whois 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. Unlike many other IP Tracking programs that send IP Whois queries only to the ARIN Whois Database, HotWhois also send queries to another Regional Internet Registries (RIRs): RIPE NCC (responsible for Europe, northern Africa, and parts of Asia), APNIC (Asia Pacific Internet Community) and LACNIC (Latin American and Caribbean region). HotWhois uses 88 whois servers all around the world to obtain information on 120 domain zones that include Generic Top Level Domains like: .com, .net, .org, .edu, .gov, .info, .int, .mil, .biz, and many other Country Code Top Level Domains. 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), Spanish (.es), Saudi Arabia (.sa), Peru (.pe), Panama (.pa), Greece (.gr,), Malaysia (.my) 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.
