Dedicated server networks

Dedicated servers are connected to Servercore's network infrastructure by default and can be connected to:

Some Chipcore Line servers are connected only to a public network; you cannot connect them to a local area network.

To connect a server to both a public and a private network, use separate network interfaces (aggregated network interface group):

  • internet port;
  • port for local network.

You can view information about server ports in the Control Panel: in the top menu, click Products → Dedicated Servers → Servers → server page → tab Ports.

The server is automatically included in the shared VLAN for the public network, and is allocated one IPv4 public address from a shared subnet.

If only one dedicated server is ordered for an account, a VLAN for a private network is not allocated. A VLAN for a private network is automatically allocated when ordering the second and subsequent dedicated servers for an account. One VLAN for a private network is allocated per account in one pool. If you need a VLAN for a private network, for example, to set up connectivity with a firewall or a cloud server, create a ticket.

You can view a list of all VLANs in the Control Panel: in the top menu, click Products → Dedicated Servers → Network → tab VLAN.

To connect to a network, you may need to configure network interfaces on the server.

If a dedicated server is unreachable over the network, you can connect to it via the KVM console. For Chipcore Line servers, you can order the additional service IP-KVM access for 3 hours or boot into recovery and diagnostics mode.

Blocked ports

To protect the Servercore infrastructure from malicious network activity, certain TCP/UDP ports are blocked, including port 25 (e-mail mailings).

If a port is not subject to these restrictions, check its availability from the OS using the Nmap utility.
