How to display all cached DNS entries on Windows 11
The Windows operating system uses a cache to store DNS entries. DNS (Domain Name System) is the core technology of the Internet used for communications. Specifically the IP address used to look up domain names.
#When a user types a domain name into their browser, one of the first tasks performed when a site loads is to find its IP address. This process requires access to a DNS server. Typically, the Internet Service Provider's DNS servers are used automatically, but administrators may switch to other DNS servers because they may be faster or provide better privacy.
Switching DNS providers may also help bypass Internet censorship if DNS is used to block access to certain sites.
Windows uses DNS resolver caching to speed up lookups. Each DNS lookup is added to the cache to speed up continuous access to the domain. Sometimes, entries can become old and may point to the wrong IP address. Our tutorial for troubleshooting browser hosting issues still works today. Reloading can help because it clears all cached items and starts loading again.
Show all cached DNS entries
The cache entry list can be used for a variety of purposes. Webmasters and developers can check that properties are assigned the correct IP addresses, and users may be interested in viewing all entries, for example, to find out which domains were visited during a session.
- Use the shortcut Windows-R to open the run box.
- Type cmd.exe and press Enter.
- Type ipconfig /displayDNS to run the command.
Windows returns all cached DNS entries in a long list. You can also redirect the output to a plain text file by running the command ipconfig /displayDNS > %USERPROFILE%\Desktop\dns.txt. This will save the output to the file dns.txt on your desktop.
The same command can also be run using PowerShell:
- Open Start, type PowerShell and select the result. If you have terminal installed, type terminal and select the result.
- Run the commandpowershell "Get-DnsClientCache | Format-Table -AutoSize".
Output uses better format. You can also use the command powershell "Get-DnsClientCache | Format-Table -AutoSize" >%USERPROFILE%\Desktop\DNS.txt to redirect the output to a text file.

How to view and refresh dns cache in Linux
Mar 07, 2024 am 08:43 AM
DNS (DomainNameSystem) is a system used on the Internet to convert domain names into corresponding IP addresses. In Linux systems, DNS caching is a mechanism that stores the mapping relationship between domain names and IP addresses locally, which can increase the speed of domain name resolution and reduce the burden on the DNS server. DNS caching allows the system to quickly retrieve the IP address when subsequently accessing the same domain name without having to issue a query request to the DNS server each time, thereby improving network performance and efficiency. This article will discuss with you how to view and refresh the DNS cache on Linux, as well as related details and sample code. Importance of DNS Caching In Linux systems, DNS caching plays a key role. its existence

Advanced Usage of PHP APCu: Unlocking the Hidden Power
Mar 01, 2024 pm 09:10 PM
PHPAPCu (replacement of php cache) is an opcode cache and data cache module that accelerates PHP applications. Understanding its advanced features is crucial to utilizing its full potential. 1. Batch operation: APCu provides a batch operation method that can process a large number of key-value pairs at the same time. This is useful for large-scale cache clearing or updates. //Get cache keys in batches $values=apcu_fetch(["key1","key2","key3"]); //Clear cache keys in batches apcu_delete(["key1","key2","key3"]);2 .Set cache expiration time: APCu allows you to set an expiration time for cache items so that they automatically expire after a specified time.
