Firewalls
Define inbound and outbound rules to control traffic to your instances. Create a firewall group in Network → Firewalls, set rules (protocol, port, source CIDR), and apply to instances.
VPC
A VPC creates an isolated private network within a region. Instances in the same VPC communicate over private IPs with no bandwidth charges. Learn more about CIDR notation.
Floating IPs
Static public IPs you can reassign between instances instantly. Free when attached (see Billing).
Load Balancers
Distribute traffic across instances with health checks, forwarding rules (HTTP/HTTPS/TCP), and SSL termination via Let's Encrypt.
API Access
Manage networking programmatically with network:write scope. See Authentication.
