Internet Protocol (IP) is the set-of-rules/language that unifies the Internet and therefore forms the basis of things like WWW, telnet, and ftp connections. A computer's IP address is its unique address on the internet, it’s “internet name,” by which other computers recognize it. Carleton IP’s begin 137.22…..
Dynamic Host Configuration Protocol (DHCP) is software that allows the computer to retrieve the necessary IP details from a central server each time it boots. DHCP is the mechanism by which Carleton assigns IP addresses.
To retrieve your IP address on a Mac go to the networks control panel under system preferences. For PC users, go to Start-->Run and type in cmd. Once in cmd, type ipconfig.
137.22... means you are connected to the network. Check your settings in Internet Options and in the Network Connections control panel. Turn off proxies, turn off firewalls. In Windows Service Pack Two firewalls are a common problem. Make sure your computer is set to have an IP Address configured automatically via DHCP.
10.. means your computer can see the internet and but you are not yet registered. Go to https://registrar.res.carleton.edu. This page may take up to a full minute to load. If it loads, follow the instructions on the page. If it fails to load, check the settings in Network Connections and Internet Options. Turn off proxies and firewalls. In Windows Service Pack Two firewalls are a common problem.
192... means you have been booted off the network for a DMCA violation or a virus and should contact Kevin at x4336.
0.0.0.0, Media Disconnected, or blank means you cannot connect to the network. A restart very often solves this problem. If it does not, make sure the media is not disconnected, as in make sure the cable is firmly connected from into both the active, stickered port and the computer. Are you getting link lights? Link lights, the small lights on your ethernet card, when lit, mean that there is a link between your computer and the network. Some cards combine the link light and the traffic light: if everything is working, the light will be solidly lit most of the time, but will blink when it sees traffic on the network. If there are no link lights, there may be a problem with the Ethernet card. Check the network adapters in the Device Manager? in the Hardware tab of the computer's properties, look for yellow exlamation points or question marks that point to hardware problems. Do new drivers need to be installed? Is the hardware lodged firmly into the computer? Malware is also known to hamper internet connectivity: be sure no viruses or spyware are ruining computer settings. Is it a port problem?
