说明
dnswalk is a DNS debugger that checks zone configurations for common errors and inconsistencies. It performs zone transfers and analyzes the resulting data for problems like lame delegations, missing PTR records, and invalid data. The tool identifies issues including orphaned CNAME records, duplicate A records, missing reverse entries, and records pointing to non-existent hosts. It helps DNS administrators maintain zone health and catch configuration errors. dnswalk traverses the zone hierarchy, optionally recursing into subdomains to provide comprehensive validation of DNS infrastructure.
