whois 5.5.7 Intelligent client for the WHOIS directory service
whois searches for an object in a WHOIS (RFC 3912) database. It is commonly used to look up the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system. It can automatically select the appropriate server for most queries.
For historical reasons, this package also includes
mkpasswd, which encrypts passwords using
crypt(3) and is unrelated to the Expect command of the same name.
