Let's see if I understand your question... Network level refers to the 3rd level of the OSI model. The network level you work with packets and IPs. Scanning normally refers to mapping something with a large scope. I would have to assume that scanning the network level would be scanning a range of IPs to find which are active and mapping them. A network map is very useful and should be on of the first parts of any penetration test (I do hope this is a pen test and not a hack). Normally you would start with something completely passive so I would prefer using a network sniffer and gathering as many packets as possible. From this you can assemble a rudimentary map of the network and get a general feel for what is going on. Then you can advance to more active scanning methods with MUCH caution. Check out nmap and Ethereal - a very common network scanner and packet sniffer. Oh, and don't get into trouble.

Hi!
It depends on the context: antivirus, exploit, update server, etc...
Good luck!
