This report examines how private and special-purpose IPv4 addresses (RFC1918, 127.0.0.0/8, 0.0.0.0/8, etc.) appear in global DNS records indexed by DNSDB, quantifies the scale of such occurrences, presents concrete examples (including glue records exposing internal host IPs and DNS-based distributed-database usages), and explains the security risks of leaking internal addressing information while recommending against publishing internal-only DNS mappings publicly.
