+@defun network-lookup-address-info name &optional family
+This function is used to perform hostname lookups on @var{name}, which
+is expected to be an ASCII-only string, otherwise an error is
+signaled. Call @code{puny-encode-domain} on @var{name}
+first if you wish to lookup internationalized hostnames.
+
+If successful it returns a list of Lisp representations of network
+addresses (without port numbers), otherwise it returns @code{nil}.
+
+By default both IPv4 and IPv6 lookups are attempted. The optional
+argument @var{family} controls this behavior, specifying the symbol
+@code{ipv4} or @code{ipv6} restricts lookups to IPv4 and IPv6
+respectively.
