I have a device on my network that is at a static address ( This device is connected to a network switch, that is also connected to the rest of my network. My problem is that I need to be able to find that device on the network, to run some software/ssh/etc. When I connect my laptop directly into the switch and set a static IP (, I can find that device and do what I need, but then I don't have internet. Here is a crude drawing of what my problem is. Where Device 1 has the static IP, and Device 2 doesn't. I can find Device 2 on my network.

enter image description here

Device 1 also has a specific DNS and subnet mask if that matters. Any help would be appreciated.

  • With a managed switch, you could look at its MAC table and follow the cable. However, consumer-grade hardware and host configurations/issues are explicitly off-topic here, see the help center. You might want to try on Super User.

  • Hey this is for business though thanks for your help.

    It sounds like you are trying to mix different networks on the same LAN. Your DHCP is giving devices one network, but you are statically assigning devices to a different network. It takes a router to route packets between networks, and the router needs to know how to reach each network.

  • @Will I'm sorry, but consumer-grade devices (as you seem to use) are just as off topic here. You know that you can configure multiple IP addresses/subnets on a single NIC, don't you?

    You seem to have a host configuration problem, and that is off-topic here. You could try to ask about that on Server Fault for a business network, but they will want you to follow reasonable business network practices. You will also need to provide network device models and configurations as we need here.

Finally, (I think) I understand your question: you have two networks and want to connect to both of them simultaneously with laptop, correct?

If you add a second (USB) NIC to the laptop you can directly connect to the left-hand network. That is the easiest method.

Another option is to connect both networks with a router. That requires all relevant nodes to be configured to use the router as gateway.

Other options include bridging both networks together, using a NAT router between the networks, and other non-straightforward methods.

  • I would be careful with connecting 2 different networks. They could be separate for a good reason such as security policy requirements. It can be a serious offense to connect an isolated network to the main network without permission. Otherwise, yeah, simply connecting a second network interface on the laptop to the second network should work fine. Just be sure to ask whoever is in charge before you proceed. Dec 5, 2022 at 2:43
  • @FrameHowitzer Agreed, but the OP talks about my network and networks not under your control are explicitly off topic here.

  • Probably true, I would agree this is not clear enough to be constructive without reworking and is probably off topic. Dec 8, 2022 at 21:31
