ZDNS is a high-speed DNS resolver library and CLI tool written in Go for performing large-scale DNS measurements and lookups. It includes its own recursive resolution code, a lookup cache, and modules for querying nearly every DNS record type with JSON output.

Use cases

• perform large-scale DNS measurements for research
• bulk resolve A, AAAA, MX, NS, and TXT records for millions of domains
• run DNS lookups from the command line with JSON output like dig
• build custom DNS scanning tools using the resolver library
• query authoritative nameservers recursively at high speed
• measure DNS infrastructure for internet measurement studies

When to choose

• you need to resolve or scan DNS records for very large domain lists quickly
• you want programmatic JSON DNS responses instead of dig's text output
• you are doing internet measurement research and need a fast, parallel DNS resolver
• you need a Go library embedding high-performance DNS resolution

When to avoid

• you only need occasional interactive DNS lookups - dig or nslookup are simpler
• you need a general-purpose DNS server or recursive resolver for a network
• you want a GUI DNS tool or DNS monitoring dashboard
