Discovery and the local
name resolution service
The discovery process uses the
name resolution service that is provided by the local operating system to
translate hostnames to IP addresses, and to translate IP addresses to
hostnames. On a UNIX system, a name resolution service might be Domain Name
System (DNS), NIS or NIS+, or a hosts file. Important information about name
resolution services is presented in
