Meaning – The term registered network ID, refers to an 8-byte name included in an IBM-maintained worldwide registry that has a structured format and is assigned to a particular IBM customer to uniquely identify a specific network.
This system allows IBM admins as well as other employees to maintain a systematic list of the network connections that are being used and new ones that have been added in.
The network ID for each network is unique and this makes it easy for duplicate ones or dangerous ones to be flagged instantly.
Example of usage – “When he joined his organization as the network administrator, the first thing he did was inspect the network connections that were in existence throughout the organization and mapped them to their corresponding network IDs. This way, he could keep track of these networks and monitor the addition or deletion of new and unwanted networks respectively.”
