 ### What is a default VPC and why can I not delete it?
 
 Scaleway currently has three regions: Paris, Amsterdam and Warsaw. One default VPC is automatically created for each region, in each Scaleway [Project](/organizations-and-projects/concepts/#project). Any new Private Networks that you create will be added to the default VPC for their region, unless you override this by specifying a different VPC.

-### How much does it cost to create a VPC, Private Network or reserved private IP addresses?
-
-The following resources and features are free of charge:
-
-- VPCs and VPC routing
-- Private Networks (except for [Elastic Metal servers](https://www.scaleway.com/en/pricing/elastic-metal/) and [Apple silicon](https://www.scaleway.com/en/pricing/apple-silicon/))
-- Reserved private IP addresses on IPAM

-### What is IPAM?
-
-**IP** **A**ddress **M**anager (IPAM) is Scaleway’s tool for planning, tracking, and managing the IP address space of Scaleway products. It acts as a single source of truth for the IP addresses of Scaleway resources, and has a number of associated functionalities to help manage your Scaleway IPs, such as the ability to reserve an IP on a Private Network and attach it to a specific resource. See our [IPAM FAQ](/ipam/faq/) for more detail.
-
-### Do resources' IP addresses on a Private Network risk changing when allocated by managed DHCP?
-
-With Private Networks' inbuilt managed DHCP, a private IP is allocated when the resource is attached to a Private Network, and released only when the resource is detached or deleted. The IP address remains stable across reboots and long power offs, and will not change except upon deletion or detachment from the Private Network.
-
-Nonetheless, you can also reserve specific IPs from a Private Network's CIDR block, and use these IPs to attach specific resources, if you prefer. See our documentation on [how to reserve IPs](/ipam/how-to/reserve-ip/).

 ## Private Networks
 
 ### What are Private Networks?
 
-Private Networks are a managed cloud service allowing you to create layer 2 ethernet-switched domains.
+Layer 2 Private Networks sit inside layer 3 VPCs. Private Networks are a managed cloud service allowing you to create layer 2 ethernet-switched domains.
 
 These domains can also be called virtual LAN (VLAN). They are virtual but completely private local networks that securely connect your Scaleway resources without necessarily exposing them publicly. Scaleway resources including Instances, Elastic Metal servers, Load Balancers, and Databases are all compatible with Private Networks.
 
-### What's the difference between Private Networks and VPC?
-
-Scaleway VPC offers layer 3 network isolation, while layer 2 Private Networks are created inside a given VPC. See the VPC FAQ for [more information](/vpc/faq/).
-
 ### Can I connect multiple Private Networks to the same Scaleway resource?
 
 Yes, you can configure multiple Private Networks on the same Scaleway resource. For example, you can connect up to 8 Private Networks to the same Instance. A virtual network interface is created for each Private Network the Instance is attached to. For Elastic Metal, some additional configuration is required: check out our documentation on [configuring the network interface](/elastic-metal/how-to/use-private-networks/#how-to-configure-the-network-interface-on-your-elastic-metal-server-for-private-networks).

 Yes, when you create a Private Network both an IPv4 and an IPv6 CIDR block are defined. The IPv6 CIDR block is defined automatically and "invisibly" by default at the time of creating the Private Network. It cannot be modified either at the time of creation, or afterward.
