The Name Service Switch determines where your system will
look for host information when it needs to resolve a host name to
an IP address.
For all types of information except host information, you
can configure your system to use NIS (one of the NFS Services),
NIS+ (the next generation of NIS), or the local /etc file, in any order. However, we recommend that
you do not configure your system to use both NIS and NIS+.
For host information, you can configure your system to use
BIND (DNS), NIS, NIS+, or the /etc/hosts file. As mentioned above, we recommend that you do not
configure your system to use both NIS and NIS+.
For more information on the Name Service Switch, see “Configuring the Name
Service Switch”.
