Static and dynamic IP addresses on one NIC

I am working on highly specialized test equipment in a university lab. I am communicating to the equipment via TCP/IP on a static 192.168.0.XXX subnet. My laptop and various pieces of equipment connect trough a switch. Also, I can connect to the university internet access (no wireless available in the lab) using a dynamically assigned address. I can configure my NIC to communicate to the equipment or the internet but not both. I can’t use a router because university policy prohibits it. I can’t have the research equipment get addresses dynamically because that too is prohibited. Is it possible to have both static and dynamic IP addresses on one NIC?

Software/Hardware used:
Windows 7

Thanks. We'll let you know when a new response is added.

You can try multihoming. An alternate form of multihoming does not require a second network adapter; instead, you assign multiple IP addresses to the same adapter on one computer. Microsoft Windows XP and other operating systems support this configuration as an advanced IP addressing option. This approach gives you more flexibility to control incoming network connections from other computers.

    I do not know if I can help you with an answer but I am definitely curious about how to do it. Sadly, I think you would need two network ports (NICs) on your laptop to have them both connect at once in absence of a wireless solution. Good luck.

    I think Dwiebsick's answer should work but I've never tried it and can't where I am right now. Another possibility, what if you used a VM with the VM network adapter set for NAT using the 192.168.x.x range?

    This issue interested me so I looked around a bit. The followings links may shed some light: http://www.networkworld.com/columnists/2004/110104gearhead.html http://www.petri.co.il/configure_tcp_ip_to_use_dhcp_and_a_static_ip_address_at_the_same_time.htm Still, I believe the best solution is a NAT device between you and your devices and the rest of the network. I understand that might not be available due to policy. Cheers!

    Hi Ranteng Im also accept the NAT as solution for your problem, but firstly i woul like to know something, your server is a Windows or LINUX ? because, if you cant use a Router, then you should see in your server, if you can do a NAT, then follow the steps. Good Luck
