No wonder you're confused. Replace "NIC" with "network" to understand the syntax to start with, but you should also pick up some other books to really understand summarization and classless versus classful routing. I think they are referring to a network number assigned by the Network Information Center (NIC). The NIC used to assign addresses. These days network numbers are assigned by an ISP or one of the regional addressing authorities such as the American Registry for Internet Numbers (ARIN), the Asia-Pacific Network Information Center (APNIC), or the R�seaux IP Europ�ens (RIPE). A NIC address usually refers to the data-link-layer address burned into the Network Interface Card (NIC), for example an Ethernet address like 00:00:0C:12:23:56. That address goes by many names: NIC address Data-link-layer address Burned-in addres (BIA) Hardware address Physical address Media Access Control (MAC) address I have real fun talking about MAC MACs, since I work with Macintoshes a lot. ;-) _______________________________ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > Confused?
