Gyro Cloud Istanbul: additional IPv4 addresses

1. What is an additional IPv4 address?

Extra IPv4 addresses that point to the same server as its primary address. Use them to publish services on separate addresses (e.g. web and mail), to give a customer a dedicated address or to send traffic from a different source address.

• Limit: up to 5 additional addresses per server (open a ticket if you need more).
• Price: 2 EUR per address per month (the TRY amount is shown in the panel), metered hourly from your prepaid balance, from the hour you add it until the hour you release it; the monthly cap is never exceeded.
• Configured automatically: the address is added to your server within seconds (as /32 on the primary interface) and kept across reboots, reinstalls and snapshot restores; no network configuration is needed.
• Additional addresses are covered by your server's network firewall / security groups automatically.

2. Adding and releasing addresses in the panel

1. Open Management > Network & Security > Additional IPv4 addresses of your server.
2. Pick the Quantity (up to your remaining allowance) and press Add IP. The confirmation shows the extra monthly total.
3. The new addresses appear in the list marked Additional; within seconds the page says "The addresses are active on the server."
4. To release an address press Release in its row and confirm. The address is removed from the server and returns to the pool; billing stops after that hour.

3. How the address looks on the server

Additional addresses are added to the primary network interface:

ip -4 addr show
# inet 203.0.113.10/24 ... ens192        <- primary
# inet 203.0.113.20/32 ... ens192        <- additional

To bind a service to a specific address set the application's listen/bind address to that IP. To use an additional address as the source of outgoing connections, set the source address in the application (e.g. curl --interface 203.0.113.20 https://example.com).

Rarely (an old guest agent on the server, or a network setup you changed completely) the panel says "The server could not configure the addresses automatically" and shows ready-made commands. Run them as root and press Apply again.

4. Reverse DNS (rDNS)

Additional addresses appear in Network & Security > Reverse DNS together with the primary address. You can request a separate PTR record for each (e.g. mail.example.com for the address that sends mail); it goes live after review. Details: snapshots, templates and reverse DNS.

5. CLI, API and Terraform

gyro server ip list 12345
gyro server ip add 12345 --count 2
gyro server ip remove 12345 203.0.113.20 --yes

API (Gyro Public API 2.16.0):

curl -H "Authorization: Bearer $GYRO_TOKEN" https://www.gyrohosting.com/api/v1/client/cloud/servers/12345/ips
curl -X POST -H "Authorization: Bearer $GYRO_TOKEN" -H "Content-Type: application/json" \
     -d '{"count":1}' https://www.gyrohosting.com/api/v1/client/cloud/servers/12345/ips
curl -X DELETE -H "Authorization: Bearer $GYRO_TOKEN" \
     "https://www.gyrohosting.com/api/v1/client/cloud/servers/12345/ips/203.0.113.20?confirm=true"

Terraform (provider gyro-hosting/gyro 0.14.0 or later):

resource "gyro_server_ip" "extra" {
  count     = 2
  server_id = gyro_server.web.id
}

output "extra_ips" {
  value = gyro_server_ip.extra[*].ip
}
