IP Address Registration
Local Internet Registries
The distribution of IP address space follows the hierarchical scheme described in RFC 2050. For Europe and parts of the surrounding area address space is allocated by IANA to the RIPE NCC (Reseaux IP Europeen, Network Control Centre) located at Amsterdam which acts as a regional Internet registry. Address space is allocated by the RIPE NCC to Local Internet Registries (IRs), who assign it to to end users. The various Internet service providers normaly act as IR and can therfore assign IP address space to their customers.
Due to technical constraints (Internet routing table size), IP address space must necessarily be assigned to the end users by their upstream Internet service provider. To request IP address space the first instance you should approach is therefore always the organization, that sells the Internet connectivity to you: your Internet service provider. If you are a customer of SWITCH, please contact us.
