This paper introduces a novel idea of achieving efficiency in cloud computing development through IPv6 implementation. Although this approach offers many benefits, it needs extra efforts to make proper selection of particular IPv6 attributes since not all of those attributes might be established at the first phase of cloud computing development. Ternary AHP is applied to tackle the problem of selection process. Finally, the analysis reveals top three IPv6 attributes that should be given priority in mind when deploying Cloud Computing over IPv6 to realize green ICT infrastructure for e-government in Indonesia.
