How do I find my DNS using cmd?

How do I do a DNS lookup?

Enter the name (domain, hostname, IP address, ) of the server or host that you want to find. You must know the IP address of the server, otherwise DNS is useless.

If the name is in the same network as the destination server, you will not need a DNS server, as it will directly be able to translate the domain name to the IP address. Example : If I need to look up www.enquiem-dechiffre.com, the IP address of the server to reach, I can easily do that by entering the address enq.mydomain.com, which is a local domain name at my computer.

Example : If I want to look up enq.com, I do not need to make a DNS query because the local server returns the same IP address.

If the name is outside my network (eg, an external host on the internet), I will need to open a TCP/IP connection to this address to retrieve the address of this server (using port 53). This connection will be used as the basis of the request and response messages sent back and forth between the destination and me.

I enter a domain name (such as d.com, ftp.unixdomain.info, .) in the address line of the Web browser, or I enter a hostname (for example, "ftp.info") in the hostname field. The results should immediately appear in the page.

When using the standard search engine of a Web browser, it is often possible to enter only part of a URL and use the "Find" function to locate the rest of the URL. For example, if I typed the following URL into the address line of my Web browser: "ftp://www.usitc.org", and then clicked the "Find" function, I would automatically receive the entire URL for the FTP site.

However, some sites use different mechanisms, requiring additional configuration. Most common are: Searching for a host on a mail server will not return the right addresses; instead, you may end up with pages similar to the one listed below.
