How do I find my IP Address and Network Settings?
The IP Address and network settings are used for addressing and routing over an Ethernet network. It is your computer or printer's logical (virtual) address.
An IP Address looks like this: 220.127.116.11
Windows 7, Vista, XP

In some cases when using a VPN over a network connection with a Windows XP computer, the VPN Session will disconnect after a period of inactivity (typically 10 to 20 minutes). This problem is caused by the Windows Service Pack 2 Firewall settings.
To fix the problem, the Windows Firewall needs to have the Cisco VPN Client program specified as an Exception:
Click on the START tab, and select:
Control Panel -> Windows Firewall
The following screen will be displayed. Click On (recommended) if not already on.
Click the Exceptions Tab which will bring up the following screen:
Click Add Programs which will bring up the following screen:
Click Browse and set the directory to look in to C:\Program Files\Cisco Systems\VPN Client.
Highlight the cvpnd program (single click), and then click Open .
Click OK as necessary.
At this stage the cvpnd program should have an entry as above. Click on OK to finish.
These settings for the Windows Firewall will stop the VPN session being terminated after 10 to 20 minutes of inactivity.
Every unit at UAB with devices connected to the UAB campus network should have a "network contact" person, even if there is no department server or local area network. At least one person within your department should be designated to be responsible for communicating your requests to DC/NS, and for assisting network users with basic configuration, software installation, computer training, and problem solving.
- Each department or unit at UAB should have an officially designated "network contact" person.
indicating who is to be considered the official contact person.
- Data Communications / Network Services (DC/NS) recommends that the contact person be a trained computer professional.
- If the "network contact" person is not a UAB employee, the department should additionally designate a contact person who is a UAB employee.

introducing the new person. If no replacement arrives before the old person departs, the last "network contact" should hand this function to their supervisor or other person in the department, who will then hand the job to the replacement person when they arrive. IP records, and any other records, should be turned in to the department for safekeeping.
- If the "network contact" left UAB without notifying DC/NS, the dean, director or department head should contact DC/NS with the name of the replacement contact person.

"Strange network problems" can be caused by DUPLICATE IP ADDRESSES. If the workstation can send traffic off its segment to another subnet in our 138.26 class B address range but can not get to a location off campus, it is very possible that the workstation IP address has been incorrectly set to use the campus gateway (18.104.22.168) instead of its own address. Problems within your building network that affect only one or two machines can be caused by duplicate addresses, also.
One way to check for duplicate IP addresses is to look in the arp cache of the machine having problems. In Win 95/98 or NT, at the DOS prompt type the command "arp -a". For entry of 22.214.171.124 you should see a MAC address starting like 00-00-a2....
A domain name such as the one described above is called a third-level domain name. There is a $500 one-time fee for creating new third-level domains. There is no additional charge for registering names within the domain once it is set up. Third-level domain names should be requested by the department network contact.
Faculty, staff and students who are involved in professional, academic, or student-social organizations are sometimes interested in hosting a web site for their group and want to use a domain name that does not end in uab.edu.
UAB cannot provide DNS (Domain Name) service for domains other than uab.edu. However, what we can do is register an on-campus server with a uab.edu name, and then you can arrange for an outside Internet Service Provider (ISP) to provide the name www.alabama_engineers.org and point it to your UAB server. The end result is that someone who types the URL www.alabama_engineers.org into their web browser will be taken to the organization's home page, which may happen to be sitting on a computer housed at UAB. Most ISP's charge a small fee for providing you with this service.
