Network

Brightbox Cloud natively supports both IPv4 and IPv6.

Each Cloud Server is on its own private VLAN and assigned a private IP address within its own /30 network all within the 10.0.0.0/8 range. The Cloud Server has one IP, given to it by DHCP, and the other IP is used by the gateway.

The gateway IP is also a recursive DNS service, also advertised by DHCP.

IPv6

Each Cloud Server is also assigned an IPv6 /64. Cloud Servers usually generate their own IPv6 address(es) from the advertised prefix using their MAC address, as per RFC 4862, though any IPv6 address within the given /64 can be used.

Some images are configured by default to generate additional temporary IPv6 address for privacy reasons and will use these addresses randomly for outgoing connections.

Access control

Access to and from each Cloud Server is controlled by our distributed firewall service.

DNS

Convenient forward and reverse DNS records are provided for Cloud Server addresses. More details are available in the DNS reference docs.

Cloud IPs

Cloud IPs are public IPv4 addresses that can be moved between Cloud Servers, Load Balancers and Cloud SQL instances. More details are available in the Cloud IP reference docs

Zones

Each zone is an independent Brightbox datacentre location with its own connectivity, so Cloud Servers in different zones may have slightly different paths to the Internet. Zones are interconnected with multiple private high-speed, low latency links.

Usage

Internet data is billed by the gigabyte, aggregated for your account. Data transferred between services within the same datacentre zone or across datacentre zones in the same region is free-of-charge.
