A decentralized domain name service localization model

Abstract： The Domain Name System(DNS) is a network infrastructure that manages the correspondence between names and IPs in cyberspace resources. While providing a wide range of domain name resolution services, it also has risks of performance and security. In order to avoid the system fragility caused by the heavy reliance on the root domain name server，which caused by the centralized tree-like hierarchy of the traditional DNS system, this paper designed a decentralized domain name service localization model. This model, through integrating multi-source data in the decentralized interconnection model, reconstructed the resolution priority records and the corresponding survival time after the domain name information was sorted to ensure the uniqueness and high priority of the domain name data. At the same time, based on the local data record reconstruction, the model realized the rapid response of the domain name resolution. The whole model consists of the local DNS data record reconstruction module and the domain name resolution service module, and realizes fast, accurate and reliable domain name resolution services.
