Guidance Notes

Address Space User

Enter the legal name and primary location of the organisation that will use this address space in the “legal-organisation-name:” and “organisation-location:” fields. If this End User has a website, enter the URL in the “website-if-available:” field. Otherwise, enter “none” in this field.

If there is any address space assigned to this End User that is not in use, indicate this in the “space-available:” field. If you answer “yes”, you can explain why the End User needs another assignment of address space in the “Network Description” section at the end of the form.

Addressing Plan

The addressing plan shows how the End User will use the requested address space. You can repeat the “subnet” row as many times as needed. Delete any empty “subnet” fields before you send the request. In the “Subnet size (/nn)” column, enter a slash notation prefix for each subnet. Each entry should be large enough to contain the number of addresses needed for that subnet over the next time period.

In order to demonstrate the predicted growth of your network, you must provide an estimate of the address space you will require over three distinct periods: Immediate, Intermediate and the Entire period. Your estimates should include interfaces used for hosts, routers, gateways, terminal concentrators and any other machines requiring one or more network interfaces. These columns can either contain numbers (for example, 128) or slash notation prefixes (for example, /25). Multiple slash notation prefixes must be separated by comma(s) with no blank spaces (for example, /25,/27).

In the “Purpose” column, write a short description of each subnet. If needed, you can write a more detailed description in the “Network Description” section at the end of this form.

In the “totals” row, add the total of each column. The total of the “Subnet size (/nn)” column should be the total amount of address space you are requesting for this assignment.

Equipment/Services Description

The equipment description will help us (RIPE NCC) to understand the requirements listed in the addressing plan and can be repeated as many times as needed. Leave an empty line before each new “equipment-name:” field.

In the “equipment/services-name:” field, enter the type of equipment/service requiring address space from this assignment.

Enter the vendor name and model number for the piece of equipment in the “manufacturer-name:” and “model-number:” fields.

If you have any more information about how this piece of equipment will use the requested address space, add this in the “other-data:” field.

Network Description

Additional information that you think will be helpful for us when we evaluate your request. A clearer understanding of the network and its addressing needs can help us to evaluate your request more quickly.

Network Diagram

A network diagram (topology map) can help us to understand the set-up of the network and its addressing needs.
