What is a private network (VPC)? Subnets and private IPs on Gyro Cloud Istanbul
1. In short
A VPC (private network) is a network shared only by your own servers, isolated from the internet and from other customers. Inside a VPC you create one or more subnets; your servers get private IPs (for example 10.10.1.10) from them.
- Servers in the same VPC reach each other over private IPs; this traffic is free and never reaches the internet.
- Another customer's VPC can use the same IP range as yours and the two networks still cannot see each other.
- A server can have both a public IP and a private IP; if you want, you can turn the public IP off and make the server private-only (Turning off the public IP).
- Private networking exists only on Gyro Cloud Istanbul (tr-ist-1) servers.
You manage private networks in two places: the Private network (VPC) tool on the server's service page (My Services → your server) and Gyro Console → Private networks (VPC). The same operations are available through the API, the gyro command line and Terraform.
2. How is isolation achieved?
Every subnet runs on its own virtual LAN in our network. Isolation has five layers:
- VLAN tags sent by your server are ignored; subnets are separated at the network level.
- On private NICs, MAC address changes, forged MAC transmits and traffic sniffing are disabled.
- You can only attach a server to a subnet in your own account (the same rule in the panel, API, CLI and Terraform).
- The VPC gateway runs every VPC in its own network stack; there is no path between VPCs.
- Private networks are carried only inside our server infrastructure; they are never exposed to the internet or other customers.

Unavailable ranges (the platform's own networks): 10.42.0.0/16, 10.43.0.0/16, 10.200.0.0/16, 10.250.0.0/16, 10.255.0.0/16.
If you need more, open a support ticket; limits are raised per account (Account limits and quotas).
4. Price
VPCs, subnets and private traffic are free. Only the VPC gateway (internet egress, port forwarding) is charged while it is on: about TRY 277.79 per month (4.99 €), metered hourly from your prepaid balance with a minimum of 1 hour; charging stops when you turn the gateway off. The euro price is fixed; the TRY amount follows the daily exchange rate (VAT excluded) and the current TRY equivalent is shown in the panel.
5. Frequently asked questions
Which products have it?
In this release only Gyro Cloud Istanbul servers.
Do servers in the same VPC see each other even if they run on different hosts?
Yes. The private network spans all our Istanbul server infrastructure; your server keeps its private IP even if it is moved.
Can I connect two VPCs?
No, VPCs are completely separate from each other.
Is private traffic charged?
No, traffic inside the same VPC is free.
