Understanding and Securing Your DNS Records with a DNS History Lookup Resource

The Domain Name System (DNS) is commonly abused because successfully attacking it reaps great rewards for threat actors and cybercriminals. Domain hijacking, for instance, can allow attackers to siphon off personally identifiable information (PII) and confidential corporate data from compromised domains. And since not all security solutions and technologies monitor DNS packets, threat actors can exploit this to infiltrate target networks.

Not all is lost, however, as regularly checking your DNS records for anomalies is an excellent proactive security measure. A DNS history lookup resource such as DNS Database Download can provide you with actionable threat intelligence.

But before we dive in and establish how to go about DNS record protection, let us first discuss the various types of DNS records that need protecting.

How a Reverse IP & Domain Lookup Can Save Organizations from Stale DNS Records

Every website that can be accessed on the Internet comes with an IP address that points to a specific domain name. Each domain-to-IP address mapping is recorded in the Domain Name System (DNS), which makes it possible for users to not have to remember numeric addresses to reach a particular website while still letting DNS resolvers do their matchmaking work. And for this to happen, a DNS record contains many crucial details about a website accessible via the World Wide Web.

Unfortunately, when a website ceases to exist, its owner may forget about its DNS records. These records are what is known as “dangling” or “stale” records, which attackers often abuse as part of their nefarious schemes.

DNS Records and Their History Matter: Beefing Up Your Cybersecurity Posture Using DNS Tools

The global cybersecurity landscape is becoming crowded both with threat actors and security solutions. When it comes to security threats specifically, attacks are becoming more and more sophisticated, and the amount of damage they cause is also increasing. In 2018, hackers stole almost half a billion personal records.

These security breaches were accomplished by using different tactics such as phishing, denial-of-service (DoS), and ransomware attacks, to name a few. And the threat actors successfully carried out these attacks, not because victims don’t use cybersecurity solutions, but because not all systems monitor every type of vulnerabilities — including the ones that have to do with DNS misconfigurations.

The key is for companies to decide which cybersecurity solutions best fit their business model strategically. For organizations that rely mainly on websites and email communications, including Domain Name System (DNS) record checks aided by a DNS database or DNS lookup tool may be their best bet.

Enhancing Packet Filtering via a Reverse IP/Domain Check

Spoofing is a cyber attack method where the adversary impersonates a legitimate user to gain access to a network or device. Once inside the target network, the attacker can then perform large-scale attacks, steal sensitive information, and inject systems connected to the network with malware.

Although there are several types of spoofing, the most common being IP spoofing. This method allows attackers to launch denial-of-service (DoS) and man-in-the-middle (MitM) attacks, two of today’s most prevalent cyber attack types. At present, we see 30,000 DoS attacks per day, whereas MitM attacks account for 35% of exploitations that target inadvertent system or software weaknesses.

The statistics may seem overwhelming, but there are strategic processes such as packet filtering that can help organizations avoid these attacks. This post features a reverse IP domain check tool — Reverse IP/DNS API — which makes packet filtering effective across the various implementation systems or technologies an organization uses. But first, let us examine how IP spoofing is used to launch DoS and MitM attacks to understand why it is crucial to detect IP spoofing.

Why Tracking Your DNS History Is Important

If you have ever published a blog post and then got so much flack for it you ended up taking it down – and you still think this would make the problem go away, think again. If your readers have your blog on their RSS feed and click on its link, they’ll still be very likely to be able to read a cached version of it.

The same is unfortunately true for domains. Every change a domain goes through is recorded on its historical WHOIS record, made possible by the introduction of passive Domain Name System (DNS) — a means to find out any modification made at some point in time to a specific domain.

As such, any bit of information related to a domain can still be seen via a passive DNS search. And this is the reason why making sure your domain has had no ties to any malicious activity throughout its entire life cycle is important.

Why Is Reverse DNS Lookup Useful?

If you work on the web, you may be familiar with Domain Name System lookups. The standard "forward" lookup uses an internet domain name to acquire an Internet Protocol address. Conversely, a reverse DNS lookup uses an IP address to obtain a hostname. Websites and applications may benefit from access to a reverse DNS lookup API which can make it easier to detect whether a site is hosted on the same server as suspicious or dangerous domains.

Malicious Websites Who Share Your IP Address Could be Destroying Your Reputation

Your website could be in danger and your good name might be in jeopardy.


More than likely, your website shares an IP address with dozens, hundreds, and possibly thousands of other websites. Any one of those websites could be operating in a negative fashion that harms your website's integrity because search engines have difficulty distinguishing between the multitudes of websites that share the same IP Address. Therefore, when search engines mark a website as malicious, every other website that shares its IP address suffers as well, leading to devastating consequences.
