Results

 

Information is given for each of the network interfaces (cards) on the machine. You may have more than one for instance if you have wired and wireless adaptors.

 

 

Description - The name and model of the adaptor.

 

Physical Address - This is the hardware address, a unique 6-byte number assigned by the manufacturer which identifies this particular network card.

 

DHCP enabled - Whether or not Dynamic Host Configuration Protocol has been enabled for the this interface. If not enabled then the interface has been given a static configuration, ie IP Address, Gateway and DNS Server. If DHCP is enabled, then on startup the interface will broadcast packets requesting configuration details which require a response from a DHCP server which will provide them. You must have a DHCP server running on your network for this to work. In general, the use of DHCP is a good idea when you have computers such as laptops joining and leaving the network.

 

IP Address - The Internet Protocol Address of the interface, which identifies it on the network as well as providing routing.

 

Subnet Mask - This shows which hosts are available within the local network.

 

Default Gateway - Any packets for addresses which are not within the local network (as defined by the IP Address and Subnet Mask above) will be sent to this IP Address. It may be that of an ADSL or Cable router, or a network interface in a computer on the network that is connected to an ISP.

 

DNS Servers - The IP Addresses of servers for Domain Name Lookups. Whilst computers are identified by numbers, people work better with words. So you might request a page at www.intervations.com, but this would need to be referred by the browser to a Domain Name Server, which would return the IP Address (140.186.104.235) which the browser then uses to actually connect to the Intervations server.
