Solve technical problems: A DNS flush on Windows, macOS, and others is often an effective solution if youРІР‚в„ўre experiencing technical problems when accessing web applications.

With a DNS flush, you can also dispose of such manipulated records with minimal effort. This so-called DNS poisoning or DNS spoofing is often used to access sensitive log-in data, for example, to online banking. If cybercriminals gain access to the DNS cache, theyРІР‚в„ўre in a position to manipulate the entries and, for example, redirect you to the wrong websites.

The information in the cache is practical for delivering web projects РІР‚вЂњ but can quickly become dangerous in the wrong hands.

Security against manipulation: You should also clear the DNS cache from time to time for security reasons.

The more comprehensive the collection of cached addresses is, the more you reveal yourself. In any case, your address storage betrays which projects you call up regularly or over a long time. On the basis of the listed addresses, including additional information such as the validity period (if given), you can get an approximate overview of your page history.

Hide search behavior: While the tracking of user behavior on the internet is primarily carried out by cookies, JavaScript, and others, the DNS cache still offers a potential target for all data collectors.

There are three reasons in particular that you should take action and set the DNS register to zero with a DNS flush, regardless of the actual validity period of the individual records: This doesnРІР‚в„ўt happen by itself: The entries remain in the cache until the defined TTL expires. For example, an entry for the domain (IPv4: 172.27.171.106), which should be valid for one error, would look as follows:Р”Р„s mentioned earlier, it makes sense to clear the DNS cache regularly. The DNS cache contains IP addresses for the respective domains or hosts as well as additional information specifying it РІР‚вЂњ such as the validity period of the record or the appropriate protocol group.

Resource data length (optional): value for the length of the resource data.

Class (optional): protocol group that the RR belongs to (mainly РІР‚СљINРІР‚Сњ for internet).

Time to live (optional): validity period of the resource record in seconds.

Record name (optional): domain name of the object for which the DNS entry was created.

РІР‚СљAРІР‚Сњ: IPv4 address (decimal value: 1) or РІР‚СљAAAAРІР‚Сњ: IPv6 address (decimal value: 28)

Record type: type of the created entry, e.g.Resource data (rdata): data that describes the record, for example address or host name.The various РІР‚вЂњ partially optional РІР‚вЂњ components include the following:

The information units or entries in the DNS cache are called resource records (RR) and are displayed in ASCII code (in compressed form).
