Summary of Relevant Experience . CentralNic currently provides SLD registration in a country code like structure. They have had about 50,000 names under management since 1995. Apparent Implementation Risks . Currently, Telnic is managing 50,000 SLD names using software developed in-house.
Registration is currently web based.
To reach the target of a million names under management will require very significant scaling from the current systems and probably the use of registrars. Because of the very finely granulated nature of the name space, the name server load characteristics may be significantly different from the current load. Caching may not be as effective when individuals are calling other individuals at low frequency rates, but at high aggregate volumes. More load prediction and performance modeling would be useful. From another point of view, it is unclear if the use of the service would ramp up at the same rate that the names might be reserved.
