N/A (No port resource — network interfaces are implicit per Droplet)

Quake AI concept: Ports

• DigitalOcean has no port concept. Droplets receive a private VPC IP automatically on creation; the network interface is implicit and not separately addressable via API. Neutron ports are explicit first-class resources with UUIDs, security group associations, and independent lifecycle.
• Allowed-address-pairs (for floating secondary IPs, VRRP high availability) are not supported in DO's VPC model. Neutron allowed-address-pairs enable virtual IP patterns used for active-standby clustering.
• DO Firewalls attach to Droplets or tags, not to network interfaces. Neutron security groups attach to ports, enabling per-interface rules on multi-homed instances.
• IP address assignment in DO is automatic; a fixed IP cannot be specified at interface creation. Neutron allows fixed_ips specification at port creation with subnet-specific allocation.
