Great. That's a feature I think any hosting provider should be offering if they charge for IPv4 addresses. My frontend does have a few features besides the typical SNI based proxying. So if you do encounter shortcomings in their load balancer, you can take a look at what I achieved on my frontend.

Thanks for the suggestion – unfortunately, the Stardust is not an option. Scaleway only allows setting up one instance in each zone; I'd need 4 and already have one. I'll probably just go for a DEV1-S.
