IP addresses are allocated to Atlas from RIPE - The European Registry for Internet Numbers. In turn, Atlas assigns those IP addresses to our customers for usage while connected to the Atlas network. The size of the IP address assignment varies and is solely based on the continually demonstrated and documented need for IP addresses.
Clients must use 80% of their existing IP addresses prior to requesting an increase in assignment. New customers will receive a minimal assignment based on their immediate requirement. Thereafter, the size of the assigned IP address block may be increased based on the requirements and justification.
IP Address Justification is required to ensure that IP addresses are being used in accordance with RIPE's policies. This is to ensure that IP addresses are not being wasted and that they are being used for their intended purpose. Internet citizens like Atlas, are having an increasingly difficult time obtaining IP addresses due to the depletion of IPv4 addresses. In order to ensure that IP addresses are available for people who need them, the justification process ensures that IP addresses assigned are being actively used.
At any time Atlas may require a customer to justify its IP address assignment. If the customer is unable to do so, its ability to obtain future assignments may be jeopardized and its existing assignment may be revoked or reduced.
How do I justify IP addresses?
When a customer requests an IP address space assignment from Atlas, the customer will need to provide technical justification as to their requirements.
You can justify IP addresses by following the steps below:
- Determine the number of IP addresses you need.
- Determine how these IP addresses will be used.
- Provide Atlas with the details in the following format (this is an example, please provide your own details):
[x.x.x.x] - hv01.example.com (Hypervisor Management IP)
[x.x.x.x] - fw.hv01.example.com (Virtualization Firewall)
[x.x.x.x] - ns1.example.com (Primary Nameserver)
[x.x.x.x] - ns2.example.com (Secondary Nameserver)
[x.x.x.x] - web01.example.com (Web Server)Automatic Denial
We will automatically deny any justification for, but not limited to, the following:
- SEO
- SSL (use SNI)
- Web servers (use name-based virtual hosting)
- Email servers (use name-based virtual hosting)
- Other Applications that can use name-based virtual hosting
- Applications that can use multiple ports on the same IP address
Additional Information
Please keep in mind that if you are requesting large subnets, you will be required to provide additional information and documentation. We will work with you to determine what information and documentation is required.
