VPCs are **opt-in** — create one when you want two or more VMs to talk to each other privately at near-line-rate without going over the public internet, or to put a fleet behind a single internet gateway. A VM that doesn't join a VPC is still fully usable; it just reaches the internet through its public IP and has no private peer network. Under the hood, every VPC is a **VXLAN segment** with its own 24-bit VNI — that's what makes them isolated, and why two VPCs can use the same CIDR and still never see each other.

The four tabs across the top are Diagram, VPCs (8), Public IPs (8), and Firewall (1).

The dashboard's **Networking** page opens to this live diagram of every VPC, every VM in one, and every public IP attached to a VM. The four tabs across the top — **Diagram / VPCs / Public IPs / Firewall** — are how you move between the visual map, the flat lists, and the firewall rules. Most network management starts and ends here. ## What you can do | Task | Where | | ------------------------------------------- | ------------------------------------------------------------- | | See your whole network at once | **Diagram** tab — interactive, click anything for actions | | Create a VPC with a custom CIDR | **VPCs** tab → **+ Create** | | Reserve a public IPv4 / IPv6 | **Public IPs** tab | | Build firewall rules and attach them to VMs | **Firewall** tab — see [Firewall](/products/network/firewall) | | Add a VM to a shared VPC | Diagram → VPC `⋮` menu → **Add VM** | | Detach a public IP from a VM | Diagram → click the blue IP chip → **Detach from VM** | *** ## Most viewed Visualize every VPC and IP, manage them inline.
