Internet Corporation for Assigned Names and Numbers (ICANN)
ICANN is the leading organisation for the administration of the Internet and its global structure, which consists of IP addresses, domain names (gTLD and ccTLD) and the DNS root servers. ICANN delegates the administration of national and generic Internet domains to national and other Internet registries.
ccNSO and IANA function under the auspices of ICANN.
Country Code Names Supporting Organisation (ccNSO)
ccNSO was founded in 2003 as a body within ICANN, providing a forum in which the representatives of national Internet registries could meet and discuss current issues which were of importance for ccTLDs at the global level. Through ccNSO, consensus and technical partnership are established and know-how exchanged regarding best practice in the administration of national Internet domains.
RNIDS is a member of ccNSO.
