To whom it may concern, insert:

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

If we do not hear from you in the near future we will assume that you insert:  
have contacted your IP service provider. insert:
