can't find ping, route and ifconfig commands.

I'm a newbie and I installed netbsd 9.0 using the iso. After
installation every thing worked fine but I am missing the the ping,
route and ifconfig commands. Since the network autoconf worked
perfectly I can install packages but I can't  find  the package that
contains them. The documentations imply that they are installed by
default. Is there something I'm missing.
