Seems like this is becoming more difficult than it really is. To the OP: You do not need a physical static ip address other than what the ISP gives for your modem. Every home Local Area Network (LAN) has 3 sets of private ips you can use as static Internal address which will then be forwarded to the router:
10.0.0.0 – 10.255.255.255
172.16.0.0 – 172.31.255.255
192.168.0.0 – 192.168.255.255
You can use dynamic ips, but a static is not prone address duplication. See below for a further description.
ANYONE behind a router can use these private ip addresses. So, the house next to me can use 192.168.1.101, the house behind me can use 192.168.1.101 and even i can use 192.168.1.101 with no conflicts. The only catch is, these ips cannot be broadcast over the Internet. Your private IP will be forwarded to the gateway or router, which then removes the private ip from the source field and replaces it with the modems ip. Otherwise, if this didnt happen there would be a bunch of black-holing going on - in otherwords the packet would be dropped at the first hop (router).Arnold
- In order for you to set your laptop with the same address everytime, you need to go to your control panel and right click on your wireless icon or whatever your connection is (wireless, wired etc) and select properties.
You can also save steps by right cilcking in your system tray on the connection icon and selecting properties. Under the general tab select internet protocol.
Tick the Use the following IP Address and enter in one of the three ranges of IPs i listed above. I use myself 192.168.1.139. I know .139 would never be used on my 4 person network. 192.168.1.100-103 would be if i was still using dynamic. So, we know no conflicts will occur.
You may need to enter in your DNS servers as well. If you lose internet connection you know this is why. In the start menu --->Run, type cmd. When you are prompted with the dos screen type, ip config /all and note your DNS address. Enter 2 of the 3 into your Preferred and Alernate. Hit ok and you should have internet access again.
