Naming, Addressing and Numbering

The Naming, Addressing and Numbering (NANI) Working Group (WG) is the leading group on naming, addressing, numbering and identifiers evolution, in particular the evolution related to the European regulation and policy emerging initiatives.

This WG addresses ETNO Member requirements and long term interests in the field of naming, addressing, numbering (and their relationship to routing) and other identifiers, by contributing to the shaping of a European level strategy.

This WG actively participates in new developments and presents ETNO positions regarding naming, addressing, numbering and identifier issues to relevant bodies, such as the European Commission, CoCom, BEREC, CEPT/ECC, ITU-T, ICANN and its Supporting Organisations, and RIPE/RIPE-NCC.
