+address before being able to query the IPv6 address. This bug has been
+fixed since, but as of this writing, only a few systems run the fixed
+version of glibc.
+.SH NOTES
+The ICMP hostname tools also ship with a nameswitch module for ICMP
+hostname lookups, which can be used to automatically look up hostnames
+over ICMP when a program calls \fBgethostbyaddr\fP(3) or any related
+function. See the \fBnss-icmp\fP(7) man page for more information.
