A Perception System for DNS Root Service Status Based on Active and Passive Monitoring

The Domain Name System's (DNS) root service serves as the backbone of the entire domain name resolution system. Its stability and reliability are pivotal to ensuring the smooth functioning of the network. To gain a real-time and comprehensive grasp of the root service's operational status, this paper introduces a perception system specifically designed for monitoring DNS root service status. This system integrates both active probing and passive monitoring techniques, providing a thorough and up-to-date understanding of DNS root resolution services within a designated network. This approach enables swift identification and resolution of any potential issues.
