Hello all,
The IP returned from the event MemberJoined (IP As String) is way off.
It comes in as 192.168.1.68
But the IP computer is not on the same IP - sorry, I do not know the correct way of writing this - the correct IP would be 192.168.0.xx.
So why does the IP 192.168.1.xx come in at all?
BTW this is my home network. Two Windows PC trying to talk using Auto Discovery
Thanks
Tim
Does that computer have a second network attached? Perhaps Ethernet and Wi-Fi?
Do you try the provided example ?
No second network. I even rebooted it.
It never displayed this behavior before - code is not new.

Do me a favor and open a command prompt and type ipconfig. What’s the result of that?
Or your DHCP config changed or have a rogue DHCP…

Windows (View your network properties) shows the ethernet controller having an IP of 192.168.1.168/24 with a gateway of 192.168.1.1. This is from my office yesterday I’m sure. But why is it holding it?
IPConfig /all does not show this at all.

The project is there:
Examples/Communication/Internet/AutoDiscovery.xojo_binary_project
I have what was a working application that worked from Mac to Windows and reverse, years ago Last time I checked, the communication was working fine from Mac OS laptop to the Windows 10 laptop, but not in the other way.
As far as I can recall, it was not necessary to be connected to the internet (I used it on WiFi) provided you have a wifi hotspot (or a computer to computer "network). But I was not able to make it working this year.
It wont work over the internet, LAN only.
IP addresses that are received from a DHCP server have a lease-length, typically 3-days, to allow users to leave for a weekend and still have the same IP when they return on Monday. It sounds like thats what you are seeing. Youd have to talk to their IT dept or directly at their router to find out what that length is. Ive seen it set to 30 days to facilitate users who travel a lot.
That said, I dont remember when Windows reorders their NIC addresses, but on macOS, theyre updated as soon as the network conditions change. You might try restarting to see if that makes your Wi-Fi the primary network connection.
Open command prompt as admin and try bellow things to get up to date with your nic’s.
ipconfig /flushdns
ipconfig /release
ipconfig /renew
But why would it appear when that hardware is not used - it was on a wireless connection when it detected the IP assigned to the Ethernet which was not connected at all?
Thanks for the answers. I do appreciate the insight and help!
Tim
Are you specifying a NIC on both ends?
No, I do the following:
ADController.Bind( 9090 )
ADController.Register("Axcys")Dont know how to specify a NIC, or even if the other end would know what it is? I thought that the big benefit was not knowing who was there, as long as we are on the same page (ADController.Register(“Axcys”) )
