While typing this I've confirmed, yes, they're randomly assigned each time.

#MAC GET DOCKER IP MAC#
I'm wondering if the MAC is randomly assigned ever time a container is spawned. Are the MAC addresses assigned here 'permanent' to the container? Or are they dynamic? I ask because I have these setup as "Network Mode: Bridge", "Use interface: Adapter 1 (Virtual Switch)" and "(x) Use DHCP" I haven't had a chance to confirm this, but I've seen other DHCP leases showing up on different MAC addresses, also using this prefix. Not at the NAS-level for the prefix, nor per-container for it's individual MAC. Is there a place in Container Station where the MAC is configurable? I've checked and didn't see anything obvious. It also works for Virtualization Station VMs. Works well when dealing with actual physical devices with individual, vendor-assigned, MAC addresses. This to allow making sure hardware MACs will always get the same IP address regardless of their local configuration. I generally setup DHCP leases for all devices on my network, regardless of whether they get manually configured for static. Ok, but aren't docker instances supposed to use a MAC starting with 02:42:AC not 02:42:0F? As per: THAT would have made it immediately obvious when I googled for it. Lo and behold it was a docker instance I'd set up via Container station. I finally managed to hit upon something using that MAC via some DNS logs. So I had to start slogging my way through various arp tables on numerous servers, switches, services and my network router. Using a prefix of 02:42:0F Searching various online resources for that prefix turned up no results. I had an unexpected MAC address showed up on my network. I had a devil of a time tracking this down.
