Show or Hide answer How can I obtain IP addresses?

Ask your Local Internet provider or find a member of the RIPE NCC (LIR)

Show or Hide answer I need address space. Do I need to become a RIPE NCC member?

I need address space. Do I need to become a RIPE NCC member?

If you require a /32 or larger of IPv6 address space, need to make end user assignments and access member only services you should become a RIPE NCC member, also known as an LIR.

If you are a small Internet Service Provider (ISPs) or end site, you can obtain an IPv6 address space assignment or sub-allocation from an upstream provider, known as an LIR to ISP allocation. If you do not make assignments to customers, you may also qualify for an IPv6 PI assignment. An IPv6 PI assignment can be requested through a RIPE NCC member. This means that you do not need to become a RIPE NCC member to obtain IPv6 address space. Please note that you can only obtain up to a /29 via an LIR to ISP allocation.

See "IPv6 Address Allocation and Assignment Policy" for more information about IPv6 allocations and assignments.

If you require IPv4 address space and access to member only services you should become a RIPE NCC Member. Members may receive a one-time /22 allocation (1,024 IPv4 addresses) from the RIPE NCC.

Show or Hide answer What is a Local Internet Registry (LIR)?

A Local Internet Registry is a term used to describe the members of the RIPE NCC. They are called LIRs because they are responsible for the distribution of address space & registration of the address space on a local level.

The LIRs also ensure that policies and procedures are followed on the local level. Organisations that become LIRs are mainly Internet Service Providers (ISPs) that assign and allocate address space on to their customers, Telecom and Enterprise organisations, as well as Academic institutions. Academic institutions are organisations that require large blocks of address space that cannot be obtained from an upstream provider.

For more information about Local Internet Registries please see the membership section.

Show or Hide answer How much do IP addresses cost?

The RIPE NCC does not sell IP addresses. Use of IP addresses is subject to membership fees being paid and renewed.

For more details see the current version of the "RIPE NCC Billing Procedure and Fee Schedule" at:

Show or Hide answer Can non-members receive registration services from the RIPE NCC?

No. Registration Services are only available to the members of the RIPE NCC. Organisations often become a member of the RIPE NCC because they need to be multihomed and use external gateway protocols (e.g. BGP4) or they need large amounts of IP address space for their operations as an Internet Service Providers (ISP).

To receive registration services from the RIPE NCC, an organisation needs to become a member of the RIPE NCC.

In most cases, organisations can obtain IP addresses from an upstream service provider and there is no need to obtain address space directly from the RIPE NCC. If your organisation is interested in becoming a member of the RIPE NCC please see this page.

Show or Hide answer Can I obtain a class C address block?

Classful addressing (class A, class B, class C, etc) is now redundant and the RIPE NCC no longer uses that terminology. This was the original model used for distributing IP addresses. It was based on classful addressing strategies and did not take into account the massive expansion of Internet use and so the system was unscalable.

Classless Inter Domain Routing (CIDR) is now one of the fundamental requirements for eligibility to receive IP address ranges.

All requests for address space must be supported by documentation showing a technically justified need for the amount of IPv4 addresses requested and requesters must show that the address space will be used efficiently and according to best current practice.

IP address space is now referred to by the prefix length or subnet mask. For example, a /24 ("slash 24") refers to 256 IP addresses (the equivalent of a former class C) and a /19 refers to 8,192 IP addresses (the equivalent of 32 former class Cs).

Show or Hide answer Can the RIPE NCC recommend a service provider in my area?

No, the RIPE NCC cannot do this. You are however, welcome to browse The RIPE NCC list of members. Please bear in mind, though, that the RIPE NCC does not make any representations as to the suitability or types of services of any of its members.


Show or Hide answer How can I influence the policies and procedures?

Anyone in the RIPE (Réseaux IP Européens) community can suggest a new policy or a change to an existing policy. You do not have to be a member of the RIPE NCC. The RIPE community is an important source of public input for the RIPE NCC. You can find out more about the policy development process at:
http://www.ripe.net/ripe/policies/

The main purpose of RIPE Meetings and RIPE Working Groups is to discuss technical and policy issues affecting Internet administration and operation in the RIPE NCC service region and beyond. The RIPE NCC reports at RIPE meetings and asks for feedback from participants about its services and projects. The RIPE community can influence the annual activity plan of the RIPE NCC. You can find the current RIPE NCC activity plan at:
http://www.ripe.net/publications/docs/ap.

Show or Hide answer Can I register a domain with the RIPE NCC?

No, the RIPE NCC is not involved in domain name registration. Your ISP may be able to help you register a domain name. For more information about tld (top level domain) and cctld (country code top level domain) registrations, visit the ICANN or CENTR

Show or Hide answer Does the RIPE NCC provide technical support to its members?

The RIPE NCC does not provide technical support to their members. The RIPE NCC is responsible for the management of IP address resources in its service region but is not responsible for the technical operations of its members.

Show or Hide answer Where can I find who is responsible for domain name registration in my area?

For generic TLD's (.com/.net/.org) contact a gTLD registrar.

For country code TLD's (where 'area' = 'country') see

Show or Hide answer I am an Internet Service Provider. Should I register with RIPE?

No. You do not have to register with RIPE, as RIPE is an open forum and has no formal membership. RIPE is a collaborative organisation open to all parties interested in the wide area IP networks.

Show or Hide answer I would like to change providers. Can I take the addresses currently used to the new provider?

There are two types of IPv4 address space: Provider Aggregatable (PA) and Provider Independent (PI).

  • If you are an End User with PA addresses and change to a new provider, you are required to return the addresses to your previous provider.
  • If you are an LIR and have PA address space allocated by the RIPE NCC, you do not have to return the address space if you change your upstream provider.
  • PI address space remains assigned to its End User as long as the criteria for the original assignment are met.

For further information on PA and PI address space please refer to the RIPE Document "IPv4 Address Allocation and Assignment Policies in the RIPE NCC Service Region".
