Realism Features

• Weighted query type distribution matching typical enterprise DNS traffic
• Mixed internal/external domains per template (e.g. 35% internal for A records, 90% for SRV)
• Response code distribution — ~86% NOERROR, ~10% NXDOMAIN, ~3% SERVFAIL, ~1% REFUSED
• Realistic answer data — CNAME chains, MX priorities, SRV records for Active Directory services
• 40 real-world external domains and 30 internal service hostnames
• Transport variation — UDP (~97%) vs TCP (~3%), higher TCP for TXT and SOA queries
