Service Specification Public IP address (IPv4)

This English version is provided for convenience only. The German version is legally binding; in the event of any discrepancy between the two versions, the German version shall prevail.

1. Brief description

centron Public IP address (IPv4) enables virtual machines (VMs) operated in the centron Cloud to be connected to the public internet at network level. The public IPv4 address serves to handle incoming and outgoing network traffic.

Assignment to the internal, private IP addresses of the customer platform takes place automatically via standardised address translation procedures (Network Address Translation – NAT). For incoming data traffic, a Public IPv4 address can be dynamically assigned to an active virtual machine of the Customer or removed from it again.

For outgoing data traffic, the assigned address enables the virtual machines to access external internet resources securely by means of source address translation (Source Network Address Translation – SNAT).

2. Key features

centron Public IPv4 offers the following basic functions:

• access to virtual machines from the internet via a public IPv4 address
• enabling outgoing connections from virtual machines to the internet
• assignment and removal of Public IP addresses to and from existing virtual machines
• automatic provision of a Public IPv4 address upon initial use of internet-enabled networks or resources

It is used in conjunction with existing network and compute resources within the centron platform.

3. Service plans

centron Public IPv4 is provided as a uniform service without different service plans.

It is used exclusively in conjunction with other cloud resources, in particular virtual machines and networks.

4. Metrics

Billing is per reserved or assigned Public IPv4 address per hour or part thereof.

Costs are incurred irrespective of whether the address is actively used, for as long as it is assigned to the Customer.

5. SLA specifics

No separate service level agreements are agreed for centron Public IPv4.

The availability of the network connection is governed by the SLA provisions of the underlying infrastructure and network services.

6. Backup

Backup and recovery functions are not part of the service.

7. Additional terms

The protection of the systems accessible via Public IPv4 lies entirely within the Customer’s area of responsibility. This includes, in particular, protection against unauthorised access from the internet, for example through:

• use of firewall rules
• use of security groups
• system hardening and secure configuration of the applications

The Customer is responsible for the proper use of the assigned Public IP addresses and must, in particular, ensure that no activities take place that may lead to a negative reputation of the IP addresses used.

The Provider accepts no responsibility for the reputation of the public IP addresses on the internet and has no influence on external rating mechanisms or blacklisting by third parties.
