Network
The Yandex BareMetal network infrastructure includes public and private networks that ensure server connectivity with the internet and between each other.
Public network
A public network is an internet-facing network to which all servers are physically connected. In public networks, ephemeral and dedicated public subnets are available.
For more information about public networks, see Public network.
Private network
A private network is a local network to which all servers from a single pool are connected. In private networks, private subnets, VRFs, and private connections to cloud networks are available.
For more information about private networks, see Private network.
MAC addresses of network interfaces
You can look up the MAC addresses of the BareMetal server network interfaces on the server information page under Network interfaces.
Server routing table
The BareMetal server’s OS must feature a routing table that sets traffic routes for the public and private networks at the same time.
The actual server routing table configuration depends on your OS; however, the routing table must follow this example:
0.0.0.0/0 via <network_interface_in_public_network>
10.0.0.0/8 via <network_interface_in_private_network>
172.16.0.0/12 via <network_interface_in_private_network>
192.168.0.0/16 via <network_interface_in_private_network>
