In the Solaris environment -- and in UNIX environments in general -- information about computers and networks is maintained in sets of tables on one or more local or remote management servers.
For example, information about computers (hosts) is maintained in a hosts and/or ethers table, and information about networks and subnetworks is maintained in a networks and/or netmasks table. Different network management servers may store dissimilar sets of network management tables, with information about different groups of networks and computers maintained on each. Distributed network management environments, like NIS and NIS+, provide mechanisms for sharing management tables across management servers from a central location.
When you delete a computer, subnetwork, or network with AdminSuite, what you are really deleting is the references to these entities in their respective tables. For example, when you delete a network, you are not physically deleting an entire network and all the computers on it, but rather the references to this network in the networks and/or netmasks table on the current management server. The network or computer will still exist, but you will no longer be able to manage it on that management server through AdminSuite or any other tool that makes use of these tables.
Note: You can delete computers, static (real) subnetworks, and static networks, but you cannot delete dynamic networks or subnetworks because, technically, they do not really exist.
