.SH SYNOPSIS
very few hosts will return more than one name, and then there is
little chance to compress it.

\fBgetaddrinfo\fP(3), which may cause addresses resolved from a
symbolic hostname to be returned in the wrong order (i.e. not
consistent with RFC 3484). This will in turn cause \fBidnlookup\fP to
requests only on IPv6 (or if the Internet service provider for the
remote host blocks ICMP packets, which is wrong, but unfortunately not
all too uncommon), \fBidnlookup\fP will have to time out on the IPv4
