dnsmap is mainly meant to be used by pentesters during the information gathering/enumeration phase of infrastructure security assessments. During the enumeration stage, the security consultant would typically discover the target company’s IP netblocks, domain names, phone numbers, etc
Subdomain brute-forcing is another technique that should be used in the enumeration stage, as it’s especially useful when other domain enumeration techniques such as zone transfers don’t work (I rarely see zone transfers being publicly allowed these days by the way).
