FAQ: New Members
- How can I get IP addresses?
If your organisation meets our criteria, you can apply for membership and receive a block of addresses. The general criteria are:
- Your organisation has a legally established office in the RIPE NCC service region
- Your organisation will need its own routable block and a large amount of addresses
If your organisation does not meet our criteria, you should approach an upstream provider, also known as a Local Internet Registry (LIR) or Internet Service Provider (ISP).

- Can I register a domain with the RIPE NCC?
We do not register domain names. Your Internet Service Provider (ISP) may be able to help you register a domain name. For more information about Top Level Domain (TLD) and country code Top Level Domain (ccTLD) registrations, see the websites of either ICANN or CENTR.
- What is a Local Internet Registry (LIR)?
An LIR is a member of a Regional Internet Registry (RIR), such as the RIPE NCC.
They are called LIRs because they are responsible for the distribution and registration of Internet number resources at a local level.
LIRs also ensure that RIPE community policies and procedures are followed at a local level.
Organisations that become LIRs are usually ISPs that assign and allocate Internet number resources to their customers, telecommunication companies, enterprise organisations and academic institutions.
- Do I need to become an LIR?
Organisations that will need their own routable block and a large amount of Internet number resources should become an LIR. Any organisation with a legally established office in the RIPE NCC service region can become an LIR.
If you need a smaller number of Internet number resources, you should first contact one of our members in your country.

What types of organisations become an LIR?
Most of our members are ISPs that assign and allocate Internet number resources to their customers, telecommunication companies, enterprise organisations and academic institutions.
Our members benefit from the independence of having their own allocations or assignments of Internet number resources.
- What are the benefits of membership?
RIPE NCC members (LIRs) are able to get their own blocks of Internet number resources. We call this an 'allocation'. You can find information about first allocations in the RIPE Document store at:
Once you get your first allocation block, you can start using the IP addresses in it for your internal infrastructure or for your customers. We call this 'making an assignment'. You have to ask us to carry out these assignments for you.
You can also get an Autonomous System Number (ASN). You use this to announce your allocation on the Internet and set up reverse delegation. You can read about how to request an ASN at:
- Can I buy IP addresses from the RIPE NCC?
IP addresses are a shared public resource and are not for sale. Effective management of this resource is vital to maintain the stability of the Internet. If you become an LIR and get Internet number resources from us, you will have the right to use them, providing your keep your membership up-to-date and you follow our allocation and assignment policies. You can find more information about these policies at:
- Can I obtain a Class C address block?
Classful addressing (Class A, Class B, Class C, etc) is no longer in use. Classless Inter Domain Routing (CIDR) replaced it and is now one of the fundamental requirements for eligibility to receive Internet number resources.
- How do I request Internet number resources?
You will have to send us documentation that proves the technical need for any Internet number resources that you request.
Quantities of address space are now referred to by their prefix length (or subnet mask). For example, /24 refers to 256 IP addresses, the equivalent of a former Class C. /19 refers to 8,192 IP addresses, the equivalent of 32 former Class Cs.

- Why should I get IP addresses from my ISP rather than from the RIPE NCC?
The RIPE NCC cannot guarantee that any address space that it allocates can be globally routable. This is because filtering policies that bigger network providers use around the world are beyond our control.
The best way to avoid filtering problems is to make sure that your network is numbered into the address range of a larger network (such as that of your upstream ISP), so that many addresses can be aggregated and announced globally as a single route. Because a global route has a shorter prefix, it will increase its chances of being unaffected by the filtering policies of large transit providers.
It is in the interests of the Internet community as a whole that the number of separate routes in the global routing tables be kept to a minimum. This is why we encourage organisations to obtain address space from upstream ISPs wherever possible.
- Can the RIPE NCC recommend a service provider in my area?
The RIPE NCC is a strictly neutral and objective organisation. Therefore we cannot make recommendations about service providers. We also do not make any recommendations about the suitability of or types of services offered by any of our members.
