## What it is
dnslookup is a simple command line utility for making DNS lookups against a specified server. It supports all major DNS protocols including plain DNS, DNS-over-TCP, DoH, DoT, DoQ, and DNSCrypt.

## Use cases
- look up DNS records from the command line
- test a DNS-over-HTTPS resolver
- debug DNS-over-TLS or DNS-over-QUIC servers
- query a DNSCrypt resolver using a stamp
- check DNS resolution with a specific resolver IP
- get machine-readable JSON output for DNS queries
- perform PTR reverse lookups for IP addresses

## When to choose
- you need to test or debug modern encrypted DNS protocols like DoH, DoT, DoQ, or DNSCrypt
- you want a lightweight dig alternative with JSON output
- you need to verify a custom or self-hosted DNS server is responding correctly

## When to avoid
- you need advanced dig features like zone transfers, batch queries, or complex record filtering
- you want a GUI DNS tool
- you need continuous DNS monitoring rather than one-off lookups
