DNS Use Cases

For developers: optimize API performance

# Find fastest DNS for your API endpoints
net-benchmark dns benchmark \
  --domains api.myapp.com,cdn.myapp.com \
  --record-types A,AAAA \
  --resolvers production.json \
  --iterations 10

Result: Reduce API latency by 100–300 ms.

For DevOps/SRE: validate before migration

# Test new DNS provider before switching
net-benchmark dns benchmark \
  --resolvers current-dns.json,new-dns.json \
  --use-defaults \
  --dnssec-validate \
  --output migration-report/ \
  --formats csv,excel

Result: Verify performance and security before migration.

For self-hosters: prove Pi-hole performance

# Compare Pi-hole against public resolvers
net-benchmark dns compare \
  --resolvers pihole.local,1.1.1.1,8.8.8.8,9.9.9.9 \
  --domains common-sites.txt \
  --rounds 10

Result: Data-driven proof your self-hosted DNS is faster (or not!).

For network admins: automated health checks

# Add to crontab for monthly reports
0 0 1 * * net-benchmark dns benchmark \
  --use-defaults \
  --output /var/reports/dns/ \
  --formats excel,csv \
  --domain-stats \
  --error-breakdown

Result: Automated compliance and SLA reporting.

For privacy advocates: test encrypted DNS

# Benchmark privacy-focused DoH/DoT resolvers
net-benchmark dns benchmark \
  --doh \
  --resolvers privacy-resolvers.json \
  --domains sensitive-sites.txt \
  --dnssec-validate

Result: Find fastest encrypted DNS without sacrificing privacy.
