The base set information collected and recorded into the above structure is as follows, these entities are associated with a particular Network Domain.
Addresses
These are the inidividual IP addresses, initialy these are simply inferred from the Subnet and it's mask.
The An IP address entry starts as inferred information from the subnet information subnets (it and is associated with a that subnet obviously). once Once network audits commence and the import of information from NMIS and Open-Audit Enterprise

is available the Addresses are confirmed as being live, in use and gain associations with Endpoints.
Endpoints
These are discovered interfaces / MAC addresses. An endpoint is a Network Attachment, in the majority of cases this is the MAC address. These are discovered through NMIS, Open-Audit Enterprise or the hosts own ARP table if that subnet is directly attached. An endpoint could in some cases not have a MAC, if the interface does not have a MAC, it would then only have an interface name. Endpoints are associated with an Address (potentially a history of addresses if the device changes IP). Endpoints also record other information found from the device such as, interface name, interface description, speed and the manufacturer (taken from the MAC's OUI).
Gateways
These are devices discovered from NMIS and Open-Audit which have more than one IP interface. The devices are automatically associated with the subnets they are attached to. A Gateway is associated with two or more subnets. A subnet can have one or many gateways. NOTE: For a gateway discovered from NMIS to be imported as a gateway the node must have a location assigned to it. You will find each of a routers interfaces as an endpoint also (there is no associations between the endpoint s and gateways).
