You may want to try my pkgsrc/net/gethost package. From the DESCR:

 gethost does hostname and IP lookups. It supports IPv6.
 It uses standard libraries and it doesn't necessarily
 use DNS resolver only. So it is useful for troubleshooting
 /etc/hosts, for example. gethost can also time each lookup
 to show the elapsed time in seconds. Multiple lookups
 can be done on one command-line.
