What is it?

doggo is a command-line DNS client, similar in purpose to dig, written in Go. It prints lookup results in a compact, color-coded, tabular format and can also emit JSON for scripts. Queries can be sent over plain UDP and TCP, or over encrypted transports such as DNS-over-HTTPS, DNS-over-TLS, DNS-over-QUIC and DNSCrypt.

Beyond basic lookups, doggo supports iterative delegation tracing with --trace, reverse DNS queries, and multiple resolvers with configurable query strategies. It handles EDNS options such as Client Subnet, NSID, Cookies and Padding, as well as IDN names via punycode conversion and the ndots and search settings. Defaults can be set through a TOML config file or DOGGO_* environment variables.

The project is distributed as prebuilt binaries, through many package managers, via go install, and as a Docker image. It was inspired by the Rust-based dog tool.
