The file /etc/yp.conf is read from ypbind(8) at startup or when receiving signal SIGHUP. The entries are used for the initial binding. Valid entries are
domain nisdomain server hostname
domain nisdomain broadcast
ypserver hostname
broadcast
hostname can either be an IP address or the system's DNS name. If it is the system's DNS name, this name needs to be resolveable without the help of NIS, before NIS is used.
If for a specific domain the broadcast option and fixed server are given, ypbind-mt tries at first the given servers before falling back to broadcasting for a running server.
Content of /etc/yp.conf can be changed by DHCP client, for more info see ypbind(8).
