Re: License server on AWS
@nikolay_piskun , can you confirm if you mean reboot OR a instance start/stop?
We have no known observation when a reboot changes the mac address, however a start/stop of EC2 instance is expected to do so. The MAC addresss isn't static. You need to consider it as dynamic just like the default IP address assigned to your instance. A static MAC address can be obtained using the Elastic Network Interfaces (ENI) feature mentioned above. The MAC address assigned to an ENI will not change. It is tied to that interface. As long as you keep the ENI, you also keep the MAC address.
