The Dossier Current DNS report provides a comprehensive, one-page report detailing current DNS information obtained when conducting a threat indicator search on a threat indicator. The Current DNS report records show the active DNS records associated with the threat indicator. The Current DNS report includes the following information:

• TYPE: The type of record associated with the threat indicator. DNS record types include the following:
  • IPv4 Address Record (A): The IPv4 Address Record (A) returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host, but it is also used for hostname DNSBLs, or storing subnet masks in RFC 1101.
  • IPv6 Address Record (AAAA): The IPv6 Address Record (AAAA) returns a 128-bit IPv6 address, most commonly used to map hostnames to an IP address of the host.
  • CNAME: CNAME data is provided from the upstream authoritative server. 
  • Nameserver (NS): The Nameserver (NS) delegates a DNS zone to use the given authoritative name servers.
  • Mail Exchange Record (MX): The Mail Exchange Record maps a domain name to a list of message transfer agents for that domain.
  • Start of Authority Record (SOA): The Start of Authority Record (SOA) specifies authoritative information about a DNS zone, including the primary nameserver, the email of the domain administrator, the domain serial number, and several timers related to refreshing the zone.
  • Text record (TXT): The Text Record (TXT) was originally for human-readable text in a DNS record. Since the 1990s, however, this record more often carries machine-readable data, such as specified by RFC 1464, opportunistic encryption, Sender Policy Framework, DKIM, DMARC, or DNS-SD
• VALUE: The IP address (IPv4 or IPv6), nameserver, mail exchange record, the start of authority record, or text record associated with the DNS record type. Clicking any of the hyperlinked records indicated in light blue under the VALUE column will display the Summary report for the selected VALUE.
• REVERSE: The reverse DNS record associated with the DNS type record. Clicking any of the hyperlinked records indicated in light blue under the REVERSE column will display the Summary report for the selected reverse DNS record.
• TTL: The TTL (Time-to-Live) as designated by Infoblox and our data partners.
