My IP isn't listed on my D-link routers active clients?

Your router is showing you the "number of dynamic DHCP clients". You have configured your computer to not be a dynamic DHCP client, so it is not showing in the list.

If you want a "static" IP address, you should find a way onto the "DHCP reservations list". This is usually done by giving the router the MAC address of your computer's network interface and choosing which IP address you want.

From D-Link's website:

Q: How do I utilize DHCP reservation in my DIR series router?

A: DHCP Reservation is used to assign a specific IP address to a specific MAC address on the LAN.

To do so, use the following steps:

1. Open a web browser and type the IP address of the DIR series router into the address bar (default is http://192.168.0.1).
2. The default username is admin (all lower case) and the default password is blank (leave empty) unless one has been assign. Click on OK.
3. Click on the Setup tab at the top and then click on Network Settings on the left-hand side.
4. Scroll down to Add DHCP Reservation.

5. Input a desired name and address. Click the Copy Your PC’s MAC Address button if you want to reserve for the computer in use. You may click on the Reserve link if available to the client you are reserving the IP address.

   Note: If the Reservation address you’re creating is not for the machine that you are working from or not listed, you’ll need to obtain the MAC address of that machine.

6. Click on the Save button then on Save Settings to apply your new settings.
