Why would a computer need 2 different IP addresses? It is not necessary for normal use, but it can be a very necessary situation in workplaces or networks where many different devices are used. Let’s see how we can do this.
Example Scenario
The first case, I have 1 wifi (internet) and 1 wired (intranet) on my computer at work. It is always needed for an intranet program. But when you open a browser with an intranet, most sites do not open. We want to use 2 network connections at the same time, but we cannot use the browser internet while the intranet is open, it wants to connect over the wired intranet. we will need to enter the route to use both at the same time. Let’s follow the steps below.
First, let’s connect both networks and open the command line as an administrator.
Let’s see if there are routes already entered by entering the “route print” command. If there are routes in the 0.0.0.0 block, we will delete them and enter the IP blocks of their own two networks.
route print
When we run the “route print” command, we saw that for example “route delete 0.0.0.0 mask 0.0.0.0 192.168.16.1”, which is the Intranet route. We will delete this and then enter the blog used.
We will run the command “ipconfig” in the command line and enter it as a route by looking at the “IP blocks-Mask-Gateways” of its two networks.
ipconfig
The route we provided as the first intranet network we added is for example “route add 192.0.0.0 mask 255.0.0.0 192.168.16.1”. You will give whatever your intranet IP-mask-gateway is.
Secondly, the route we added to the wifi network is given as “route add 0.0.0.0 mask 0.0.0.0 192.168.1.1”. You will give whatever is your own wifi IP-mask-gateway.
Note: Network Destination: 0.0.0.0 Netmask: 0.0.0.0 Gateway: 192.168.16.1 Interface: 192.168.16.20 comes back on the intranet block when the computer is turned off and on, or the cable is unplugged. You need to delete this route again.
