## ipaddr-to-hostname

Arguments: ipaddr &key ignore-cache

ipaddr should be a 32-bit unsigned integer (representing an IPv4 address), an ipv6-address stucture, or a dotted IP address string. This function returns, as a string, the hostname of the machine with the given address.

if the ignore-cache argument is specified true, then the lookup will be done by querying the operating system ipaddr lookup libraries rather than using a value that Lisp has cached. The result of the lookup is still cached, however.

See also `*dns-mode*`.

See socket.htm for general information on sockets in Allegro CL.
