fix(instances): rework FAQ (#5935)

NoSuchCommand · web-flow · commit 92f54a2a9f97 · 2025-12-08T09:53:59.000+01:00
* Provided more detailed insights about Marketplace `image` and
  `local-image` concepts.
* Routed IPs are now the only available choice. Stop confusing customers
  with the term "migration".
* Private IPs no longer exist, and so do the private DNS names.

 ### What is a Marketplace image?
 
 A Marketplace is an online store that offers applications and services either built on or integrated with Scaleway’s offerings.
 
-Scaleway Marketplace provides information related to Instance images through variants named “local-images”. This information can include the Instance zone and identification, along with constraints regarding the applicable Instance types.
+A Marketplace `image` is a labeled reference to a resource that can be selected for use as the **system volume** of a newly created Instance. Depending on several criteria of the Instance, like its zone and its type, such an `image` will point to a different `local-image`, which holds the actual data that will be cloned onto the volume of the Instance.
 
-When you want to create an Instance using an image in the Instance [API](https://www.scaleway.com/en/developers/api/instances/), you need to specify the local-image UUID matching the zone and Instance type constraints you fetch from the marketplace API.
+When you want to create an Instance using an image in the Instance [API](https://www.scaleway.com/en/developers/api/instances/), you can specify either the `label` of the `image` or the UUID of the `local-image`.

 ### What are the benefits of Dedicated Resources?
 
 Dedicated Resources give you a more stable experience for compute-demanding workloads, offering benefits such as:
 * No “noisy neighbors”,
 * No “burst effects”,
 * Optimization for demanding and specific needs.

 ### Why do I have to specify the CPU architecture when creating an image from a volume?
 
 ARM and x86-based Instances use a different instruction set, which requires specifying the architecture of the platform when creating an image from a volume.
 
 An ARM CPU uses a Reduced Instruction Set Computing [RISC](https://en.wikipedia.org/wiki/Reduced_instruction_set_computer) architecture, while an x86 CPU uses a Complex Instruction Set Computing [CISC](https://en.wikipedia.org/wiki/Complex_instruction_set_computer) architecture.

 ### Can I reach my Instance using a DNS hostname instead of its IP address?
 
-Yes, each Instance has two DNS hostnames associated with it:
+Yes, each Instance can be reached through a DNS name of the form `<instance-uuid>.pub.instances.scw.cloud`, which points to the main IP address of the Instance, be it IPv4 or IPv6. You can either use this name directly or configure a [CNAME record](/dedibox-dns/concepts/#resource-records) linking to it.
 
-* A **public DNS hostname**: `<instance-uuid>.pub.instances.scw.cloud`
-* A **private DNS hostname**: `<instance-uuid>.priv.instances.scw.cloud`
-
-Both are automatically updated when the Instance moves to another hypervisor, also changing its IPv6 and private IPv4. You can either use these hostnames directly or configure a [CNAME record](/dedibox-dns/concepts/#resource-records) linking to it.
+The target of this name is automatically updated whenever you change the list of Flexible IPs attached to the Instance.

-### Which Instances support IP Mobility?
-
-All ranges are compatible except for Instances using the “bootscript” feature, which has [reached its end of life (EOL)](/instances/troubleshooting/bootscript-eol/).
-
-### Can I enable “Routed IP” on my bootscript Instance?
-
-Instances using a bootscript are not compatible with Routed IPs. As the bootscript feature has reached its end of life (EOL), refer to [this tutorial](/instances/troubleshooting/bootscript-eol/) for migration instructions.
-
-### Can I revert the migration to “Routed IP”?
-
-No, the migration is permanent.
-
-### Will my Instance retain its public IPv4 after migration?
-
-Yes, your existing flexible public IPv4 will be converted to a routed one and will remain unchanged after migration.
-
-### Will my Instance retain its public IPv6 after migration?
-
-No, you will receive a new IPv6 after migration.
-
-### Will my Instance retain its private IPv4 after migration?
-
-No, the Scaleway private IP will be removed after the migration.
-
-### Will my Instance retain its VPC private IPv4 after migration?
-
-Yes, your VPC configuration will remain intact after migrating to a routed public IPv4.
-
-### Can a resource with a routed IP communicate with a resource with a NAT IP?
-
-Yes, they can communicate with each other using their public IPs.
-
-### Are there any limitations on IP autoconfiguration with the routed IP feature?
-
-Currently, additional routed IPv6 addresses do not autoconfigure on CentOS 7, 8, 9, Alma 8, 9, Rocky 8, 9 after migration.
-Additional routed IPv4 and IPv6 addresses are not autoconfigured post-migration on Ubuntu 20.04 Focal. However, the primary IPv6 continues to be configured via SLAAC. These limitations are currently being addressed.
-If you encounter connectivity issues with Ubuntu Focal Instances having multiple public IPs, consult our [troubleshooting guide](/instances/troubleshooting/fix-unreachable-focal-with-two-public-ips/).
