Subnet — Overview
What is a Subnet?
A subnet (subnetwork) is a range of IP addresses partitioned within a VPC. When you create a virtual machine or other compute resource, it is placed in a specific subnet and receives an IP address from that subnet's address range.
Each subnet belongs to exactly one VPC and cannot be shared across different VPCs.
Two Types of Subnets
FPT Cloud provides two types of subnets, differentiated by their ability to route traffic to the Internet:
| Type | Description |
|---|---|
| Routed | A subnet with Internet routing via NAT gateway. Virtual machines in this subnet can connect to the Internet (outbound). |
| Isolated | A subnet with no Internet routing. Virtual machines can only communicate internally within the VPC. Suitable for workloads that require network isolation. |
Scope of Application
Subnets can be created in both types of VPC:
- General VPC — A general-purpose network environment, used for most workloads.
- Specific VPC — A specialized network environment, used for specific network configuration requirements.
What You Can Do
- Create a subnet — Define the CIDR range, subnet type (Routed/Isolated), gateway address, DNS, and static IP pool.
- View the subnet list — Check the name, CIDR, gateway, DNS, and creation date of each subnet in the VPC.
Navigation
Subnets are managed within the context of each VPC:
