IP routing service
An IP address (whether IPv4 or IPv6) is the number assigned to a computer or any computer equipment for it to have access to the Internet. This number identifies the computer within the network.
Internet address space management is co-ordinated globally by several organisations following a hierarchical structure: ICANN monitors the management of these resources worldwide. In Europe, RIPE is responsible for managing these addresses and below that come the Local Internet Registries (LIRs), like RedIRIS, which is responsible for managing address space (both IPv4 and IPv6) previously allocated by RIPE and which RedIRIS places at the disposal of its affiliated institutions so that they have the IP addresses required for Internet access.
With the IP addressing service, which was begun in 1989, RedIRIS ensures its users have the IP addresses they need to log on to the Internet. RedIRIS offers both IPv4 and IPv6 addressing.
