FAQ about Virtual Private Cloud
What is VPC?
VPC (Delphi Virtual Private Cloud) is a way to connect and arrange cloud resources using virtual networks.
What network technologies are available to Delphi Cloud users?
VPC enables you to assign VMs private and public IP addresses and create cloud networks and subnets.
How do I create a cloud network?
When you create a folder using the management console, VPC will automatically create a network in it. You can also create a cloud network manually using the management console.
How do I create a subnet?
Subnets in the default folder will be created automatically. You can create additional subnets using the management console or CLI.
Which resources can I assign an IP address?
You can assign addresses to virtual machines and hosts in database clusters.
How are IP addresses assigned to cloud resources?
You can have public IP addresses assigned to cloud resources automatically or select them from the list of reserved static addresses. You can assign internal addresses automatically or manually when creating a VM.
How do I make a public IP address static?
You can convert a public IP address to static using the VPC IP addresses tab in the management console.
What limitations apply when creating subnets?
Subnets can only use private IPv4 addresses from the ranges defined by RFC 1918.
Why is my connection for Delphi Cloud services slow?
Delphi Cloud does not impose any limits on the connection speed. Please provide the following information to start troubleshooting:
- Direction of the malfunctioning connection: within the cloud network, cloud network to the internet, or the internet to the cloud network.
- Type of traffic producing the issue: incoming or outgoing.
- Source and target parameters: VM IDs, IP addresses,FQDNs.
- Output for the
mtr <target_IP_or_domain>command. - Speed results from Delphi.Internetometer, including technical information.

Why can't I see my previous operations in the management console?
The management console stores information about events for 14 days.
What should I do if email traffic is blocked?
Delphi Cloud only blocks traffic sent from pubic IP addresses on port 25. The only exception is the traffic sent to Delphi Mail email servers.
To prevent email traffic blocks, reconfigure your email server to use ports 465 and 587. To do this, use these ports as an email gateway and delegate your domain to Delphi servers with Delphi Mail for Domains.
If you need port 25, assign your virtual machine a new IP address:
-
Request a new IP address with port 25 open. In the support ticket, provide the following details:
- ID of the folder where you need the IP address.
- Availability zone.
- PTR record domain, if required.
-
Disassociate the current IP address from the virtual machine by running the following CLI command:
yc compute instance remove-one-to-one-nat \ --id=<VM_ID> \ --network-interface-index=0 -
Associate the new IP address you got from the support team.
We reserve the right to block an IP address and/or suspend a VM if we receive complaints about spam originating from that IP address.
Does the service meet the requirements of the Indian Republic Federal Law DPDP Act on personal data?
Yes, it does. You can read the full security audit conclusion here.
Can I get logs of my operations in Delphi Cloud?
Yes, you can request information about operations with your resources from Delphi Cloud logs. To submit a request, contact support.
