Show the TTL of A, AAAA, MX, NS, TXT, CAA and SOA records with its source
Show the TTL of A, AAAA, MX, NS, TXT, CAA and SOA records with its source: exact from a validated DNSSEC signature (RRSIG Original TTL) or the resolver's remaining cache time (normally a lower bound), plus the SOA negative caching TTL. Use when an agent plans a DNS change and must know how long old records live. Input: ?domain=example.com.
