Confirming Host Name Resolution

Typically, the computer on which you want to install Oracle Database is connected to a network.

Ensure that the computer host name is resolvable through a Domain Name System (DNS), a network information service (NIS), or a centrally-maintained TCP/IP host file, such as /etc/hosts. Use the ping command to ensure that your computer host name is resolvable. For example: 

ping myhostname
pinging myhostname.example.com [192.0.2.2] with 32 bytes of data:
Reply from 192.0.2.2: bytes=32 time=138ms TTL=56

If your computer host name does not resolve, then contact your System Administrator.
