Susrećete li^(Are) se s problemima dok surfate internetom? Ne otvara li se web stranica na koju pokušavate doći? Ako ne možete pristupiti web stranici, razlog za ovaj problem može biti zbog  DNS poslužitelja i njegove predmemorije za rješavanje.

DNS ili sustav naziva domene^{(Domain Name System)} vaš je najbolji prijatelj dok ste na mreži. Pretvara naziv domene web stranice koju ste posjetili u IP adrese kako bi ga uređaj mogao razumjeti. Pretpostavimo da^(Suppose) ste posjetili web stranicu i za to ste upotrijebili naziv njezine domene. Preglednik će vas preusmjeriti na DNS poslužitelj i pohranit će IP adresu web stranice koju posjećujete. Lokalno, unutar vašeg uređaja, nalazi se zapis svih IP adresa^{(record of all the IP addresses)} , što znači web stranice koje ste posjetili. Kad god pokušate ponovno pristupiti web stranici, pomoći će vam da prikupite sve informacije brže nego prije.

Sve IP adrese su prisutne u obliku predmemorije u DNS Resolver Cacheu^{(DNS Resolver Cache)} . Ponekad, kada pokušate pristupiti stranici, umjesto da dobijete brže rezultate, ne dobijete nikakav rezultat. Stoga morate isprazniti predmemoriju resetiranja DNS razrješača da biste dobili pozitivan izlaz. ^{( Therefore, you need to flush the reset DNS resolver cache for getting the positive output. )}Postoje neki uobičajeni razlozi zbog kojih DNS predmemorija s vremenom ne uspijeva. Web stranica je možda promijenila svoju IP adresu i budući da vaši zapisi imaju stare zapise. Stoga možda imate staru IP adresu, što uzrokuje probleme dok pokušavate uspostaviti vezu.

Drugi razlog je pohranjivanje loših rezultata u obliku predmemorije. Ponekad se ovi rezultati spremaju zbog DNS lažiranja^{(DNS spoofing)} i trovanja, završavajući u nestabilnim mrežnim vezama. Možda je stranica u redu, a problem je u DNS predmemoriji na vašem uređaju. DNS predmemorija može postati oštećena ili zastarjela i možda nećete moći pristupiti stranici. Ako se nešto od ovoga dogodilo, možda ćete morati isprati i resetirati predmemoriju za razrješavanje DNS -a za bolje rezultate.^(DNS)

Baš kao i predmemorija DNS razrjeđivača, na vašem uređaju postoje dvije druge predmemorije koje možete isprati i po potrebi resetirati. To su predmemorija memorije i predmemorija sličica. ^{(Memory cache and the Thumbnail cache.)}Memorijska predmemorija sadrži predmemoriju podataka iz memorije vašeg sustava. Predmemorija sličica^(Thumbnail) sadrži minijature slika i videozapisa na vašem uređaju, a također uključuje i minijature izbrisanih. Brisanjem predmemorije memorije oslobađa se dio memorije sustava. Dok brisanje predmemorije sličica može stvoriti malo slobodnog prostora na vašim tvrdim diskovima.

Kako isprazniti^(Flush) i resetirati ^(Reset)DNS predmemoriju^{(DNS Cache)} u sustavu Windows 10

Postoje tri metode primjenjive za ispiranje predmemorije vašeg DNS razrješavača u ^(DNS)sustavu Windows 10^{(Windows 10)} . Ove metode će riješiti vaše probleme s internetom i pomoći vam da uspostavite stabilnu i funkcionalnu vezu.

Metoda 1: Koristite dijaloški okvir Pokreni

1. Otvorite dijaloški okvir Pokreni pomoću tipke prečaca ^(Run)Windows Key + R.

2. Upišite ipconfig /flushdns u okvir i pritisnite gumb OK ili polje Enter .

3. Na ekranu će se na trenutak pojaviti cmd okvir^{(cmd box)} koji će potvrditi da će se DNS predmemorija uspješno izbrisati.^{(the DNS cache will get successfully cleared.)}

Metoda 2: Korištenje naredbenog retka

Ako ne koristite administrativni račun za prijavu na Windows , tada provjerite imate li pristup jednom ili stvorite novi administrativni račun jer će vam trebati administratorska prava da izbrišete DNS predmemoriju. Inače, naredbeni redak će pokazati grešku sustava 5^{(System 5 error)} i vaš će zahtjev biti odbijen.

Korištenjem naredbenog retka^{(Command Prompt)} možete izvoditi razne druge funkcije vezane uz DNS predmemoriju i vašu IP adresu. To uključuje pregled trenutne DNS predmemorije, registraciju vaše DNS predmemorije na datotekama hosta, oslobađanje trenutnih postavki IP adrese te također traženje i resetiranje IP adrese. Također možete omogućiti ili onemogućiti DNS predmemoriju sa samo jednom linijom koda.

1. Upišite cmd u traku za pretraživanje sustava Windows^{(Windows Search)} , a zatim kliknite na “ Pokreni kao administrator^{(Run as administrator)} ” da otvorite povišeni naredbeni redak^{(Command Prompt)} . Ne zaboravite^(Remember) pokrenuti naredbeni redak kao administrator da bi ove naredbe funkcionirale.

2. Nakon što se pojavi naredbeni zaslon, unesite naredbu ipconfig /flushdns i pritisnite tipku Enter . Nakon što pritisnete Enter, vidjet ćete prozor za potvrdu koji potvrđuje uspješno ispiranje DNS predmemorije.

3. Once done, verify if the DNS cache is cleared or not. Enter the command ipconfig /displaydns and hit the Enter key. If there are any DNS entries left, they will get displayed on the screen. Also, you can use this command anytime to check the DNS entries.

4. If you want to turn off the DNS cache, type in the command net stop dns cache in the command line and press the Enter key.

5. Next, if you want to turn on the DNS cache, type the command net start dnscache in the Command Prompt and press the Enter key.

Napomena:^(Note:) Ako isključite DNS predmemoriju i zaboravite je ponovno uključiti, ona će se automatski pokrenuti nakon ponovnog pokretanja sustava.

Možete koristiti ipconfig /registerdns za registraciju DNS predmemorije prisutne u vašoj Hosts datoteci. Drugi je ipconfig /renew koji će resetirati i zatražiti novu IP adresu. Za otpuštanje trenutnih postavki IP adrese koristite ipconfig /release.

Metoda 3: Korištenje Windows Powershell-a

Windows Powershell je najmoćniji naredbeni redak prisutan u Windows OS -u . S PowerShellom^(PowerShell) možete učiniti mnogo više nego s naredbenim redkom^{(Command Prompt)} . Još jedna prednost Windows Powershell -a je što možete izbrisati DNS predmemoriju na strani klijenta, dok možete izbrisati samo lokalni DNS predmemoriju u naredbenom retku^{(Command Prompt)} .

1. Otvorite Windows Powershell pomoću dijaloškog okvira Pokreni ili trake za pretraživanje sustava Windows^{(Windows search)} .

2. Ako želite izbrisati predmemoriju na strani klijenta, unesite naredbu Clear-DnsClientCache u Powershell i pritisnite tipku Enter .

3. Ako želite izbrisati samo DNS predmemoriju na radnoj površini, unesite Clear-DnsServerCache i pritisnite tipku Enter .

Što ako se DNS predmemorija^{(DNS Cache)} ne briše ili ne ispere?

Ponekad možda nećete moći izbrisati ili resetirati DNS predmemoriju^{(DNS Cache)} pomoću naredbenog retka^{(Command Prompt)} , to se može dogoditi jer je DNS predmemorija onemogućena. Dakle, prvo ga morate omogućiti prije ponovnog brisanja predmemorije.

1. Otvorite dijaloški okvir Pokreni^(Run) i unesite services.msc i pritisnite Enter.

2. Potražite DNS Client Service na popisu i kliknite desnom tipkom miša na nju i odaberite Svojstva.^{(Properties.)}

4. U prozoru Svojstva^(Properties) prijeđite na karticu Općenito^(General) .

5. Postavite opciju Vrsta pokretanja^{(Startup type)} na Automatski,^(Automatic,) a zatim kliknite na OK za potvrdu promjena.

Sada pokušajte očistiti DNS predmemoriju i vidjet ćete da se naredba uspješno izvodi. Slično tome, ako iz nekog razloga želite onemogućiti DNS predmemoriju, promijenite vrstu pokretanja u Disable .

How to Flush and Reset the DNS Cache in Windows 10

Are yoυ facing issues while surfing the internet? Doeѕ the websitе you are tryіng to reаch doesn’t open? If you’re unable to аccess the website then the reаson behind this issue might be because of the DNS server and its resolving cache.

DNS or Domain Name System is your best friend while you are online. It converts the domain name of the website you visited into IP addresses so that the machine can understand it. Suppose you visited a website, and you used its domain name for doing this. The browser will redirect you to a DNS server and it will store the IP address of the website you are visiting. Locally, inside your device, there is a record of all the IP addresses, meaning the websites you have visited. Whenever you try to re-access the website again, it will help you gather all the information faster than before.

All the IP addresses are present in the form of a cache in DNS Resolver Cache. Sometimes, when you try to access the site, instead of getting faster results, you get no result at all. Therefore, you need to flush the reset DNS resolver cache for getting the positive output. There are some common reasons which cause the DNS cache to fail over time. The website may have changed their IP address and since your records have the old records. And hence, you may have the old IP address, causing problems while you are trying to establish a connection.

Another reason is the storing of bad results in the form of a cache. Sometimes these results get saved due to DNS spoofing and poisoning, ending up in unstable online connections. Maybe the site is fine, and the problem is in the DNS cache on your device. The DNS cache can get corrupt or outdated and you may not be able to access the site. If any of this has happened, then you may need to flush and reset your DNS resolve cache for better results.

Just like DNS resolver cache, there are two other caches present on your device, which you can flush and reset if needed. These are the Memory cache and the Thumbnail cache. Memory cache comprises a cache of data from your system memory. Thumbnail cache contains the thumbnails of the images and videos on your device, it includes the thumbnails of deleted ones also. Clearing the memory cache frees some system memory. While clearing the thumbnail cache can create some free room on your hard disks.

How to Flush and Reset the DNS Cache in Windows 10

There are three methods applicable for flushing your DNS resolver cache in Windows 10. These methods will fix your internet problems and help you with a stable and working connection.

Method 1: Use the Run Dialog Box

1. Open the Run dialog box using the shortcut key Windows Key + R.

2. Type ipconfig /flushdns in the box and hit the OK button or the Enter box.

3. A cmd box will appear on the screen for a moment and will confirm that the DNS cache will get successfully cleared.

Method 2: Using Command Prompt

If you don’t use an administrative account to login to the Windows, then make sure you have access to one or you create a new administrative account as you will require admin rights to clear the DNS cache. Else, the command line will show System 5 error and your request will get denied.

Using Command Prompt you can perform various other functions related to DNS cache and your IP address. These include viewing the current DNS cache, registering your DNS cache on host files, releasing the current IP address settings and also requesting & resetting the IP address. You can also enable or disable DNS cache with only one line of code.

1. Type cmd in Windows Search bar then click on “Run as administrator” to open the elevated Command Prompt. Remember to run the command line as an administrator for making these commands work.

2. Once the command screen appears, enter the command ipconfig /flushdns and hit the Enter key. Once you hit Enter, you will see a confirmation window appear, confirming the successful DNS cache flushing.

3. Once done, verify if the DNS cache is cleared or not. Enter the command ipconfig /displaydns and hit the Enter key. If there are any DNS entries left, they will get displayed on the screen. Also, you can use this command anytime to check the DNS entries.

4. If you want to turn off the DNS cache, type in the command net stop dns cache in the command line and press the Enter key.

5. Next, if you want to turn on the DNS cache, type the command net start dnscache in the Command Prompt and press the Enter key.

Note: If you turn off the DNS cache and forget to turn it on again, then it will automatically start after you restart your system.

You can use ipconfig /registerdns for registering the DNS cache present on your Hosts file. Another one is ipconfig /renew which will reset and request a new IP address. For releasing the current IP address settings, use ipconfig /release.

Method 3: Using Windows Powershell

Windows Powershell is the most powerful command line present on the Windows OS. You can do much more with PowerShell than you can do with the Command Prompt. Another advantage of Windows Powershell is you can clear client-side DNS cache while you could only clear local DNS cache in Command Prompt.

1. Open Windows Powershell using the Run dialog box or the Windows search bar.

2. If you want to clear the client-side cache, enter the command Clear-DnsClientCache in Powershell and hit the Enter button.

3. If you want to clear just the DNS cache on your desktop, enter Clear-DnsServerCache and hit the Enter key.

What if the DNS Cache is not getting cleared or flushed?

Sometimes, you may not be able to clear or reset DNS Cache using the Command Prompt, it may happen because the DNS cache is disabled. So, you need to first enable it before clearing the cache again.

1. Open the Run dialog box and enter services.msc and hit Enter.

2. Search for DNS Client Service in the list and right-click on it and select Properties.

4. In the Properties window, switch to the General tab.

5. Set the Startup type option to Automatic, and then click on OK to confirm the changes.

Now, try to clear the DNS cache and you will see that the command is running successfully. Similarly, if you want to disable the DNS cache for some reason, change the startup type to Disable.
