My work PC’s IP address is 192.168.1.99 and a server that I recovered from a co-location facility has a static IP of 10.15.20.180. So, of course, when I connected the server to our network and ping 10.15.20.180, I get no replies.
I go to Control Panel > Network and Internet > Network Connections, right-click, Properties, select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
Our network, like most, has a DHCP service. I’ll need to change to a static IP so that I can add a second IP address to the NIC (multihomed). I’ll run ipconfig /all to get my current IP.
Select the Use the following IP address: radio button, retype my static IP information then click Advanced.
Under the IP address section click the Add button and enter an IP address and Subnet mask in the same class as the server I’m trying to connect to – in this case I used 10.15.20.99 and 255.255.255.0.
Click OK to all of that and run ipconfig /all to confirm the additional IP address.
Now I ping 10.15.20.180 and I get replies.
And I can remote into the server.
