Our DNS Database Download is an extensive resource covering billions of historical DNS records and close to 1 million weekly record additions.
The data feed files—which include A, AAAA, MX, NS, TXT, CNAME, SOA, and PTR records—are downloadable in CSV for easy follow-up analysis and integration into other system sources.
We offer the most recently updated domain database with every domain name linked to its IP address and host. Get downloads for all major gTLDs.
Obtain an up-to-date DNS database archive download as Comma Separated Values (.CSV) files to stay on top of the latest changes — suspicious or not — to DNS records.
Manually parsing raw passive DNS data can be a tedious and error-prone job. With DNS Database Download, users can skip the legwork and readily turn feeds into effective defensive measures.
A and AAAA records help translate human-readable domain names or hostnames into machine-readable IP addresses, and so identify the specified resolutions between those IPs and domains.
MX records specify the mail server(s) that should receive emails for a domain name and the priority with which each server should be used.
NS records identify the DNS servers considered authoritative for their respective domain names and contain the associated DNS records.
TXT records typically hold a domain’s descriptive text, generally giving human- and/or machine-readable information to help verify domain ownership and prevent spam.
CNAME records indicate how web administrators have specified domain name aliases to point to their root or canonical domain names.
SOA records contain important administrative information about a domain name’s zone and other details such as its administrator’s email address or the length of time for refreshes, retries, when to stop responding to zone queries, etc.
PTR records are used for reverse DNS lookups and contain information on which domain name is matched with the IP address. They are opposite to A and AAAA records.
Cybercriminals may use the same infrastructure resources and leave similar signatures and traces behind. DNS history allows you to follow those leads.
Discover DNS record (A, AAAA, MX, NS, TXT, CNAME, SOA, and PTR) changes and see how threat incidents correlate. Accelerate incident response and post-breach analysis with context using current and historic domain and IP information.
Identify spam, dangerous websites, intrusions, and other web-related misbehavior.
Obtain DNS intelligence for a variety of security information and event management (SIEM); security orchestration, automation, and response (SOAR); and threat intelligence (TI) platforms. Power next-generation firewalls (NGFWs) with better DNS intelligence data points. Identify and monitor Internet assets that can be traced back to entities operating in regions known for high geopolitical cyber risks.
Establish domain/IP reputation standards based on facts and use them to reveal domains and IP addresses used by malicious actors.
In this white paper, we give an overview of the Domain Name System, or DNS, one of the pillars of the Internet.Read more
