At the end of 1991, financing of the DE-NIC again was in question, as none of the service providers were interested in taking on this burden alone.
For an intermediate time of three months, the University of Dortmund secured the DE-NIC from its own resources.
As soon, as a shutdown for common NIC services was iminent, the German service providers (DFN, EUnet and XLINK) met during the CeBIT'92 trade fair to come up with a solution for a financing model for 1992.
The model distributed the costs roughly in accordance with the market share of the three service providers.
An offer of the current DE-NIC operator was discussed. Despite it having been reasonable in the framework, it was quite heavy in pricing. It amounted to about 10% of the estimated turnover of the Internet market in Germany back in 1992. After some discussion, the offer was cut back by roughly 50%. This was considered acceptable by the service providers.
Through this, financing of the DE-NIC services was secured in 1992. This became known as the Hanover model, after the meeting place Hanover.
Some of the service providers adapted the prices for their services to cover the additional cost of financing the DE-NIC. This resulted in an increase in the price for networking services for the first time in history of Internetworking in Germany.
