Yesterday we setup DNS on our testing server. during the setup we were asked to setup our server with static IP address which is required for the DNS server. now, to avoid any IP conflict between the server and other network devices getting IP addresses from the same DHCP server, we need to exclude from DHCP the static IP address we assigned to the server. read the previous post from here “Install and Configure DNS on Windows Server 2003”
My home network computers get IP addresses from the broadband Internet router which comes with a built-in DHCP server. DHCP server assigns IP addresses dynamically to computers from a pool of available IP addresses depending from the range you have setup on the router. normally home routers come with a C class address range which can give up to 256 IP addresses. now, when you assign a static IP address to any of the computers in the network, the DHCP does not know automatically that that IP address is already taken, and whenever it receives a request from a device on the network needing an IP address, it will give out the same IP address to this device. thus creating an IP conflict on the network.
To avoid IP conflicts we need to exclude the IP address we assigned to our testing server, which was 192.168.10.49. to do that, open your browser, and type the internal IP address of your router. in my case, is 192.168.10.2. authenticate, and that should bring you to the homepage of your router.
I have a Netgear wireless router, but most of home routers have almost the same functionalities. in my case, I need to go to LAN IP Setup which should bring me to this window:
click on Add to enter the static IP address of the testing server.
after you fill out the info, click on Add and then click on Apply on the next window. that should be enough to reserve the IP address exclusively for the testing server.
