Professional IP Resource Sponsorship
As a RIPE NCC accredited LIR, we sponsor your Provider Independent address space, ASN numbers, and legacy IPv4 resources. Full compliance, zero hassle.
IPv4Center.com offers professional Sponsoring LIR services for RIPE NCC resources. We sponsor Provider Independent address space, ASN numbers, and legacy IPv4 allocations starting at €250 per year with full compliance management.
What is a Sponsoring LIR and Why Do You Need One?
A Sponsoring LIR (Local Internet Registry) is a RIPE NCC member organization that sponsors the registration and maintenance of Internet number resources for end users. If your organization holds Provider Independent (PI) address space, an ASN, or legacy IPv4 resources, you are required by RIPE NCC policy to have a Sponsoring LIR.
IPv4Center.com acts as your Sponsoring LIR, handling all RIPE NCC communications, annual reporting, compliance requirements, and database maintenance on your behalf. This eliminates the need for your organization to become a direct RIPE NCC member, saving you thousands of euros annually while maintaining full control over your resources.
Our Sponsoring LIR service is ideal for organizations that have acquired IP address space through transfers, hold legacy IPv4 allocations, or need an ASN for BGP routing but do not want the administrative burden and cost of maintaining their own LIR membership.
- Mandatory for organizations holding Provider Independent (PI) address space
- Required for sponsored ASN registrations under RIPE NCC policy
- Essential for maintaining legacy IPv4 resources in the RIPE database
- Significantly cheaper than direct RIPE NCC membership (€250/year vs €1,400+/year)
- Full compliance management and annual reporting handled on your behalf

Sponsoring LIR Service: Complete IP Resource Sponsorship Guide
Understanding RIPE NCC sponsorship requirements, costs, and choosing the right LIR
Under RIPE NCC policy, every organization that holds Provider Independent resources (PI addresses, ASN numbers, or legacy IPv4 space) must have an active Sponsoring LIR relationship. The Sponsoring LIR acts as the administrative liaison between the resource holder and RIPE NCC, ensuring ongoing compliance with registry policies.
IPv4Center.com has been providing Sponsoring LIR services since 2007, managing IP resources for organizations across Europe, the Middle East, and Central Asia (the RIPE NCC service region). Our annual fee of €250 covers all sponsorship services including initial registration, database maintenance, abuse contact management, and annual compliance reporting.
Choosing the right Sponsoring LIR is important because it affects the stability of your IP resource registrations. IPv4Center.com guarantees continuity of service, transparent pricing with no hidden fees, and the ability to transfer your sponsorship to another LIR at any time as guaranteed by RIPE NCC policy. We handle the paperwork so you can focus on running your network.
Whether you need sponsorship for a newly acquired IPv4 block, want to register an ASN for BGP routing, or need to maintain legacy resources that predate the current RIPE NCC policy framework, our team provides expert guidance through every step of the process.
