The SLA sets out the arrangements for the provision, by ICANN, of IANA numbering services, after the IANA stewardship transition takes place. The agreement will enter into force at the time of the transition. ICANN also finalisedthe Memorandum of Understanding (MoU) Supplemental Agreement with the Internet Engineering Task Force (IETF) for the performance of the protocol parameters functions.
