DNS Lookup

Perform DNS analysis for: $ARGUMENTS

Auto-detect what the user wants based on the input:

For a hostname/domain:

1. lookup_dns — all record types (A, AAAA, MX, NS, TXT, CNAME, SOA)
2. parse_hostname — eTLD, registered domain, subdomain breakdown
3. pdns_forward — passive DNS history (what IPs it has pointed to)
4. domain_shared_ns — other domains on the same nameservers
5. domain_shared_mx — other domains on the same mail servers

For an IP address:

1. dns_ptr — reverse DNS (PTR record)
2. reverse_lookup_ip — hostnames pointing to this IP
3. pdns_reverse — passive DNS reverse lookup
4. historic_reverse_lookup_ip — historical hostnames

For a nameserver or mail server:

1. reverse_lookup_ns or reverse_lookup_mx — domains using this server
2. historic_reverse_lookup_ns or historic_reverse_lookup_mx — historical usage

Run lookups in parallel. Present results in a clean table format. Highlight any unusual findings (mismatched records, missing expected records, suspiciously recent changes in passive DNS).
