What are you really trying to find out here? What problem are you trying to solve?
netmon chooses these names based on what you have set up in your network, and uses them to create objects and fields on those objects in the object database.
Remember that NetView represents devices as objects in a set of interconnected databases. And there are lots of things besides devices (networks, segments, interfaces, smartsets, etc.) in those databases. "Selection Name" is the internal name NetView uses for one of those objects, and how they are constructed is determined by what kind of an object we are talking about.
If name resolution (DNS, etc/hosts, what have you) is active, then netmon will determine the name of a device by using the system routine gethostbyaddr. This value is then used for IP Hostname and IP Name, which are often the same. And the Selection Name will then be set as something like "myhost.mydomain.com" in the object database instead of just an IP address. If these devices respond to SNMP then the interface name is returned by a query of the MIB-2 interface table, so that interface Selection Names become something like "myhost.mydomain.com:en0". Otherwise, it's all just a number from that table. Similarly routerSysName is determined by SNMP based on what the router responds when queried.
If you had no name resolution and no SNMP, all your device objects would be individual IP addresses and your map would look very strange because then netmon would have to guess about how everything is connected.

All,
We're running NetView 7.xx on Solaris and I'd like to know how is "Selection Name", "IP Hostname", "IP Name", and "routerSysName" determined? Why so many ways to get the devices name and where are the names used in NetView? Right now I can see some of these names when I run Display Object Information on our devices.
TIA,
Stephanie
