How to connect the workgroup devices with the domain devices
You can use a hosts file or a domain name server to resolve host names and IP addresses on a stand-alone or distributed deployment.
hostname
ibm1
nslookup host_name
Where host_name is the host name.
The nslookup command returns the fully qualified domain name configured on the DNS server. For example: ibm1.example.com.
ping host_name
Where host_name is the host name.
Domain names or IP addresses on a local computer can be resolved by adding entries in the local hosts file on a computer. Entries in the local hosts file have the added advantage that the system can run the application server, even when disconnected from the network. If you are using a hosts file to resolve IP addresses, the file must be configured correctly.
#IP address Fully Qualified Domain Name Short Name
102.54.11.38 ibm1.example.com ibm1
127.0.0.1 localhost.localdomain localhostSource:-
