Manage IPs and ASNs

 We are running out of IPv4 addresses. Here you can find information on managing your resources and IPv4 transfers. 

IPv6 uptake is growing quickly. We have a large allocation of IPv6 space currently available for our members.

Any organisation can request an Autonomous System (AS) number. This requires a contractual agreement with a sponsoring LIR or with the RIPE NCC.


We provide primary and secondary DNS services for reverse domains. We also publish signed zones and provide an interface for users to create secure delegations for their reverse DNS zones.

The RIPE Database contains registration information for networks in the RIPE NCC service region and related contact details.
