---

**doggo** is a modern command-line DNS client (like _dig_) written in Golang. It outputs information in a neat concise manner and supports protocols like DoH, DoT, DoQ, and DNSCrypt as well.

It's totally inspired by [dog](https://github.com/ogham/dog/) which is written in Rust. I wanted to add some features to it but since I don't know Rust, I found it as a nice opportunity to experiment with writing a DNS Client from scratch in `Go` myself. Hence the name `dog` + `go` => **doggo**.

## Installation

### Easy Install (Recommended)

```shell
curl -fsSL https://raw.githubusercontent.com/mr-karan/doggo/main/install.sh | sh
```

### Package Managers

- Arch Linux: `pacman -S doggo`
- Eget: `eget mr-karan/doggo`
- Gentoo: `emerge net-dns/doggo`
- Homebrew: `brew install doggo`
- MacPorts (macOS): `port install doggo`
- [Mise](https://github.com/jdx/mise): `mise use -g doggo@latest`
- Nix: `nix profile install nixpkgs#doggo`
- Scoop (Windows): `scoop install doggo`
- Winget (Windows): `winget install doggo`

### Binary Install

You can download pre-compiled binaries for various operating systems and architectures from the [Releases](https://github.com/mr-karan/doggo/releases) page.

Linux 32-bit ARM releases are available as `doggo-linux-armv6.tar.gz` (ARMv6) and `doggo-linux-armv7.tar.gz` (ARMv7 and 32-bit ARMv8). The `doggo-linux-arm.tar.gz` compatibility asset is the ARMv7 build.

FreeBSD, OpenBSD, and NetBSD ARMv7 releases use the explicit `doggo-<os>-armv7.tar.gz` name and retain their historical `doggo-<os>-arm.tar.gz` aliases.

### Go Install

If you have Go installed on your system, you can use the `go install` command:

```shell
go install github.com/mr-karan/doggo/cmd/doggo@latest
```

The binary will be available at `$GOPATH/bin/doggo`.

### Docker

```shell
docker pull ghcr.io/mr-karan/doggo:latest
docker run --rm ghcr.io/mr-karan/doggo:latest example.com
```

For more installation options, including binary downloads and Docker images, please refer to the [full installation guide](https://doggo.mrkaran.dev/docs/intro/installation/).

## Quick Start

Here are some quick examples to get you started with doggo:

```shell
# Simple DNS lookup
doggo example.com

# Query MX records using a specific nameserver
doggo MX github.com @9.9.9.9

# Use DNS over HTTPS
doggo example.com @https://cloudflare-dns.com/dns-query

# JSON output for scripting
doggo example.com --json | jq '.responses[0].answers[].address'

# Reverse DNS lookup
doggo --reverse 8.8.8.8 --short

# Follow the delegation chain iteratively
doggo example.com --trace

# Using Globalping
doggo example.com --gp-from Germany,Japan --gp-limit 2
```

## Configuration

Defaults for any flag can be set via a TOML config file or `DOGGO_*` environment variables, so you don't have to repeat flags on every invocation:

```shell
# ~/.config/doggo/config.toml (or $XDG_CONFIG_HOME/doggo/config.toml, ~/.doggo.toml)
strategy = "first"
color    = false
timeout  = "10s"

# HTTP/3 must be paired with a persistent HTTPS (DoH) nameserver.
nameserver = ["https://cloudflare-dns.com/dns-query"]
http3     = true
```

```shell
# Equivalent environment variables
export DOGGO_STRATEGY=first
export DOGGO_COLOR=false
export DOGGO_NAMESERVER=https://cloudflare-dns.com/dns-query
export DOGGO_HTTP3=true
```

Precedence (lowest to highest): flag defaults < config file < environment variables < command line flags. Use `--config=PATH` or `DOGGO_CONFIG` to load a file from a custom location.

[`config-cli-sample.toml`](config-cli-sample.toml) documents every supported key with its default. See the [CLI reference](https://doggo.mrkaran.dev/docs/guide/reference/#configuration-file-and-environment-variables) for details.
