I have a situation where I need to set a static IP address for a HoloLens 2 for a network that I am wired to through an Ethernet to USB-C dongle. The network is not using DHCP. The HoloLens 2 is provisioned to be an offline secure HoloLens (https://learn.microsoft.com/en-us/hololens/hololens-common-scenarios-offline-secure), so there is never the option of connecting to the target network wirelessly. I can only find options to set static IPs for the HoloLenses through the device portal if the network is available wirelessly. Even the Ethernet IP configuration settings are tied to specific network profiles and these profiles only show up for wireless networks.
Any help here would be greatly appreciated, thanks!
The USB-C Ethernet adapter settings are available in HoloLens OS Insider version currently. Please check out this reference: New Settings app
Network & Internet:
USB-C Ethernet adapters will now appear in Network & Internet.
USB-C Ethernet adapter settings are now available, including its IP address.
Start receiving Insider builds if you want to have a try.
Support for setting a static IP for an Ethernet connection is now supported in the New Settings app. This New Settings app is available in the Beta Channel of the Insider Preview program as well as the official release Windows Holographic version 21H1. If the needed release does not appear when checking for updates on the HoloLens 2, the latest release can be manually downloaded from https://aka.ms/hololens2download and installed with the Advanced Recovery Companion (ARC) tool.

I have an Ethernet-to-I2C interface box (Promira, from Total Phase), connected locally to my laptop via a USB-C to Ethernet adapter. This Promira box works fine with VPN off, but disappears when VPN is turned on. I changed to split tunneling and can make the box appear, temporarily, but the box disappears again after some brief time (it varies, but less than 5 minutes). I think I've narrowed it down to something changing in DNS, because if I reset or change DNS settings in the USB-C to Ethernet adapter while VPN is on, the device can temporarily be seen again.
I have the Promira box on a separate sub-net than my internet, which allows the split tunneling.
The Promira box (as I understand from documentation) works with IPv4. I can disable IPv6 on the USB-C Ethernet adapter, and the Promira still works.
Windows 10 laptop.
Internet Ethernet connection: 172.27.35.11
USB-C to Ethernet adapter: 169.254.189.247
Promira box: 169.254.40.66 (the Promira box has a DHCP server built in, so this varies each time the box powers up; I believe the Promira box also assigns the IP address of the USB-C adapter)
VPN uses addresses of form 10.x.x.x
Any help appreciated!
This turned out to be an issue with the Promira SW. The Total Phase engineers quickly turned around a fix for this.
After setting up volumio on raspberry, an interest feature was that you can use 'volumio.local' as the address to access the webpage hosted by raspberry, and there was not much to worry whether the ip address changed every time the raspberry connected to the local network. I was wondering how did volumio do that and how to setup an custom address for an raspberry to do the same.
It uses a system called Bonjour, which can locate devices and services on a local network using multicast Domain Name System (mDNS). See this Wikipedia article.
I have a device firmware which runs on Ubuntu operating system. And the device has Ethernet connectivity and will connected on the network.
Now i need provide these two functionalities on the device
ICMP ping client - so that a device can ping the other devices on the network.
DNS client - for faster hostname to IP resolution instead of going to DNS server all the time.
I am trying to find how can i provide these features ? Do i need to implement these features or i can get some ready made source code or libraries which i can integrate with the existing code and get the features working.
Thanks in advance.

We have developed a device that is connected to our clients network and we would like to be able to get its ip or set the ip without knowing its ip.
The device has a Linux OS.
We can save the device MAC Address before giving it to customers. We can program a service to broadcast the device IP and MAC Address to a certain IP or port/socket. We can listen to a certain port/socket for commands. Is this the right direction? Should we investigate in other network protocols other than TCP/IP?
We have seen this feature in hardware/device manufacturers provide a CD with a software that can locate their devices on a network even if they have been newly added to the network without network or ip configuration.

Using propriety broadcasting protocol is a very common technique for detecting devices on network without knowing it's name.
However there's a better option:
UPNP, is an excellent protocol for achieving your goals.
libupnp can get you started in no time.
There's a standard protocol called DHCP which allows a network device to make a broadcast request for its IP address. This protocol is widely used by network appliances. On the other hand you may scan your local network for all connected devices using ARP (address resolution protocol) using for example arp-scan utility.
How connect two emulator to lan network android? I would like to send info from one emulator to second using wifi and socket
I use Android-x86. It works great in VirtualBox and it even has a tutorial.
Just set the VM's up on their own network or even bridge them to the host machine's network. Works like a champ!!!
