delete: <p style="text-align: left; "> RIPE Internet Network Numbers Template delete: <br /> delete: <br /> D.Karrenberg delete: <br /> delete: <br /> Aug 1992 delete: <br /> delete: <br /> delete: <br /> delete: <br /> To whom it may concern, delete: <br /> delete: <br /> The RIPE Network Coordination Centre now handles all requests for IP delete: <br /> network numbers from European organisations. Our aim is to provide a delete: <br /> rapid and efficient service to all European organisations. As this is delete: <br /> a recent initiative, procedures for handling network number requests are delete: <br /> in the process of being established. Therefore we apologise in advance delete: <br /> for any duplication of effort that may be required by you due to new delete: <br /> forms and templates. As the European NIC, we require different delete: <br /> information to that required by the US and for it to be presented in a delete: <br /> format which is both easy for you to complete and for us to process. delete: <br /> Before your application can be processed any further, you will need to delete: <br /> complete the enclosed templates and return them to the appropriate delete: <br /> organisation responsible for issuing IP network numbers. In most cases delete: <br /> this will be your IP service provider or the RIPE NCC. Before delete: <br /> completion of the template, please be sure to read the following text delete: <br /> and examples carefully which will guide you. delete: <br /> delete: <br /> A new classless IP addressing scheme called CIDR has recently been delete: <br /> adopted to cope with routing table growth and address space exhaustion delete: <br /> problems in the Internet. Under this scheme it is beneficial for delete: <br /> everyone to get their network numbers allocated via their respective delete: <br /> IP service providers. Your IP service provider is the organisation delete: <br /> providing external connectivity to your network. If you are planning delete: <br /> to connect your network to other networks outside your organisation in delete: <br /> the foreseeable future we strongly urge you to get numbers allocated delete: <br /> from your current or prospective IP service provider. Alternatively, if delete: <br /> this is not likely, then you will be allocated a number from a different delete: <br /> part of the address space by the RIPE NCC. Please pay careful attention delete: <br /> to this matter. delete: <br /> delete: <br /> Class A and B network numbers are a scarce resource and some delete: <br /> justification in terms of expected network size and structure will be delete: <br /> needed before such a number can be allocated. Class A numbers will only delete: <br /> be assigned to networks which technically need more than 65000 hosts to delete: <br /> be on one network number. A detailed technical justification is needed, delete: <br /> review takes place on a global scale and the allocation process can take delete: <br /> several months. Similarly due to class B scarcity, a reasonable number delete: <br /> of class C numbers will be assigned over class B. If you can engineer delete: <br /> your network to use multiple class C numbers, it is strongly advised. delete: <br /> Please note that this is contrary to earlier recommendations where it delete: <br /> was recommended to use Bs over multiple Cs due to routing table size delete: <br /> constraints. A one page document detailing the information needed by delete: <br /> the NCC to evaluate requests for class B numbers is available from the delete: <br /> NCC if it is not enclosed with this letter; this document also includes delete: <br /> a list of recommended reading about CIDR and address allocation in delete: <br /> general. delete: <br /> delete: <br /> Appended to this letter is a blank template for IP number registration, delete: <br /> which we would be extremely grateful if you complete and return to the delete: <br /> appropriate organisation responsible for issuing IP network numbers. In delete: <br /> most cases this will be your IP service provider. It may of course also delete: <br /> be the RIPE NCC. delete: <br /> delete: <br /> If you have any further queries please do not hesitate to contact the delete: <br /> NCC. Please note that all queries should, if possible, be made through delete: <br /> e-mail and sent to <[email protected]>. If you do not have access to delete: <br /> electronic mail, then we prefer to communicate by fax rather than by delete: <br /> ordinary mail.
