DNS servers are used to translate human-readable domain names like “www.google.
com” into IP addresses. By querying a DNS server, you can determine the IP address for a particular domain name.
When you type a domain name into your browser, your computer queries a DNS server for the IP address associated with that domain name. If a DNS server doesn’t have the answer, it will look up the answer using the WHOIS database.
If you want to know the IP address for a specific domain name, you can query a DNS server. Querying a DNS server is like asking a postal service for the location of a package.
The DNS server will look up the IP address for you and return it to your computer.
There are a few things you need to know before querying a DNS server. First, you need the domain name and the IP address for the domain name. Second, you need the correct IP address format. Third, you need to know the DNS server’s IP address. Fourth, you need to know the correct port number for the DNS server. Fifth, you need to know the correct query type for the DNS server.
Sixth, you need to know the correct query parameters for the DNS server. Seventh, you need to know the correct time zone for the DNS server. Eighth, you need to know the correct user name and password for the DNS server. Ninth, you need to know the correct IP address for the DNS server’s administrative interface. Tenth, you need to know the correct port number for the DNS server’s administrative interface.
After you have all of the information, you can query the DNS server. The following examples show how to query a DNS server for the IP address for google.
