Doggo
doggo is a multi-protocol DNS lookup client, performance analyzer, and diagnostic troubleshooting tool. It functions as a command-line utility for performing DNS queries across various transport protocols, including UDP, TCP, HTTPS, TLS, and QUIC.
The project distinguishes itself through a focus on secure and distributed resolution. It implements encrypted DNS standards such as DNS over HTTPS, DNS over QUIC, and DNSCrypt, and provides DNSSEC validation to verify chains of trust for signed domains. Additionally, it can execute queries from global geographic locations via an external API to analyze regional resolution differences and measure response latency across multiple resolvers.
The tool covers a broad range of diagnostic capabilities, including reverse DNS lookups, glue record inspection, and the simulation of client locations using EDNS extensions. It supports batch query processing and provides both human-readable colored output and machine-parsable JSON exports for automation.
The software is distributed as a pre-configured container image for various architectures.
