I have a MikroTik Router providing DHCP to the various networks on my homelan. Each device seems to get a regular host name collision, and so the router appends a number to the end of the existing host name. My computer is currently called “Machine-8272537”. I tried fixing it a few times, setting different timeout/lease time parameters and disabling “privacy protection” on the devices, but nothing fixes it. Been like this 3 years now. I just kinda ignore it.
I have an extension on this, in that a triple tap on the switch by the doors, will also lock the doors after 60 seconds.
