Downloading XL-Whois 5.1.1 from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this software available. The XL-Whois installer is commonly called XL-Whois.exe. This free software is a product of Alain Rioux. The following versions: 5.1, 4.2 and 4.1 are the most frequently downloaded ones by the program users. We recommend checking the downloaded files with any free antivirus. The software is included in Internet & Network Tools.
From the developer:
XL-Whois is a tool to make multiple advanced whois requests. It supports domains such as Whois, Network Whois, and DNS Records. It can automatically read IPv4, hostname, domain name, and IPv6 data from your clipboard and perform whois requests. XL-Whois stores responses from Network Whois requests in database and cache. This database can be sent to others, who can import them into their program for reading.
