Network Interfaces (NIC)

Virtual Network Interface Controllers

Virtual machines and Containers attach to VPC subnetworks via a Virtual Network Interface Controller (NIC / NetworkInterface).

Persistent Private IP Binding:

• Private IP allocations are assigned from the VPC CIDR pool during initial instance or container bootstrapping.
• Assigned private IP addresses remain permanently bound to the workload across reboots, hardware preset changes, and live migration events.

ubuntu@demo-web:~$ ip addr show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    inet 10.42.0.12/16 brd 10.42.255.255 scope global eth0

In-cluster DNS

Workloads are configured to use the VPC gateway as their default DNS resolver. It resolves <workload-name>.msrv.internal to the workload’s private IP address (for example, ctr-deadbeef.msrv.internal → 10.0.0.5), so services can reach each other by name instead of hard-coding private IPs.
