To display the contents of the Domain Name System (DNS) cache on a Windows machine, you can use the "ipconfig" command. To do this, follow these steps:
Open a command prompt. To do this, press "Win+R", type "cmd", and press "Enter".
At the command prompt, type the following command:
ipconfig /displaydns
This command will display the contents of the DNS cache, including the DNS names and their corresponding IP addresses.
It is important to note that the DNS cache only stores a limited number of entries, and it is not a complete record of all DNS names and their corresponding IP addresses. The cache is used to speed up DNS lookups by storing the results of previous queries, so that they do not need to be performed again.
If you want to clear the DNS cache, you can use the following command:
ipconfig /flushdns
This command will remove all entries from the DNS cache, forcing the system to perform a new DNS lookup for each name it needs to resolve. This can be useful if you want to refresh the DNS cache or if you are experiencing issues with DNS resolution.
It is also possible to view and manage the DNS cache using the DNS Client service, which is a Windows service that manages the DNS cache and performs DNS lookups. To access the DNS Client service, you can use the Services console (services.msc) or the Task Manager.
