IANA is responsible for the delegation of [[IP Address]]es to [[RIR]]s. In their turn, each [[RIR]] (Regional Internet Registry) is responsible for the allocation of IP addresses depending on the zone/area they are managing. In the same way, when a RIR requests for more IP Addresses for allocation, IANA evaluates the request and is able to make an additional allocation for [[RIR]]. <ref>[http://www.iana.org/numbers/ IANA IP Addresses]</ref> | IANA is responsible for the delegation of [[IP Address]]es to [[RIR]]s.
