The Domain Name System (DNS) is crucial for network communication as it translates domain names into IP addresses. DNS logs provide valuable insights into network health, such as identifying timeouts during the resolution process and detecting malicious activities like unusual patterns or spikes in requests. Understanding the anatomy of a DNS log helps administrators troubleshoot issues related to network connectivity and security. Datadog offers integration with various DNS providers and provides tools for efficient monitoring and analysis of DNS logs, including Logging without Limits™ and Pattern Inspector.
