Need static MAC address

[actocoa]

I am planning to deploy a license server of GrapgOn Go-Global as a VM. It requires a static MAC address to function. How can I acquire a static MAC address. I know I can reserve a static internal IP, but I found no reliable info online if reserving a static internal IP automatically guarantees that the MAC address comes with it is also static. Anyone can help?

Hi @actocoa,

Welcome to the Google Cloud Community!

MAC addresses are generated based on the internal IP. However, MAC addresses aren't universally unique, so relying on their uniqueness for licenses isn't advisable, as there could be multiple machines globally with identical MACs.

To reuse a specific MAC address, either assign the same internal IP again or opt for a reserved internal IP [1].

I hope this answers your question. Thank you.
