Static VS DHCP for Vultr VPS
-
What is the general opinion here for static vs DHCP settings on a Vultr VPS? I always set them static, but the Vultr website suggests DHCP.
-
Why would you change them? They are configured automatically on VM creation. I would not make them static.

It's more of a mentality thing for me. I'm so used to setting servers to always have a static IP. I was just wondering if there were any drawbacks of either scenario on Vultr.

Drawback on Vultr is if you need to image, if you have an issue or they need to push changes to DNS or gateways, you won't get them. Vultr is not meant to run static.
-
I think an important aspect here is to remember that you are trusting Vultr to run your infrastructure, but are second guessing their settings.

You're right, Good point. Thanks for bringing that up.
-
I think that it is primarily a fallback mechanism. It protects a little against overlapping IPs, provides a central registry, some degree of double checks.

Far as I've seen dhcp addresses stay with the server until they are destroyed.
Could they change on reboot or during a live boot? I don't mind using dynamic DNS I just don't always have control over the customers dns...
Good question though. Something I may need to get cleared up.

They are permanent. It's just how Vultr manages the network settings.

@scottalanmiller Just curious since I don't have any workloads on Linode... Does Linode handle it the same way? DHCP?

Never looked, I think that everyone does. It's kinda the standard.
-
I know Azure does, and AWS
-
Checked, Yes, Linode uses DHCP. It would seem crazy not to for any cloud vendor, if they have any network change they need to push it out automatically and DHCP is really the only method.
-
@scottalanmiller Right, it makes perfect sense in the case of network changes.
