Read a DNS record field by field

Enter one explicit presentation-format record. The lab separates its shared fields from type-specific RDATA so you can see what each value controls—and what the record cannot prove.

Use absolute-owner. TTL IN TYPE RDATA. Comments, directives, parentheses, relative names, and multi-line records are outside this focused lab.
