A ``#'' indicates the beginning of +a comment; characters up to the end of the line are +not interpreted by routines which search the file. +.Pp +When using the name server +.Xr named 8 , +this file provides a backup when the name server +is not running. +For the name server, it is suggested that only a few addresses +be included in this file. +These include address for the local interfaces that +.Xr ifconfig 8 +needs at boot time and a few machines on the local network. +.Pp +This file may be created from the official host +data base maintained at the Network Information Control +Center +.Pq Tn NIC , +though local changes may be required +to bring it up to date regarding unofficial aliases +and/or unknown hosts.
