First of all, nslookup is a simple but very practical command-line tool. We principally use it to find the IP address that corresponds to a host, or the domain name that corresponds to an IP address (the process of what we call it \u201cReverse DNS Lookup\u201d). Nslookup allows itself to be used in the command-line of the operating system in question. For Windows users, they start the service via the command prompt. For Unix users, they use a terminal window. Additionally, there are now a number of services that can make using nslookup online possible.<\/p>
Note: <\/strong>The name “nslookup” actually stands for \u201cname server look up.\u201d<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t

Besides that, Nslookup retrieves the relevant address information directly from the DNS cache of name servers. We can achieve this process through two different modes that the user can choose from. In the non-interactive mode, the tool inspects the resource records, which is what the address entries in the DNS cache are called. These are stored in the local name server, in a standard way. The mode is especially well suited for simple queries, for which a single domain entry needs to be looked up. When you want to use a different DNS server for the research and complete more complex search processes, you need the interactive mode. We need to start the command-line program separately at first.<\/p>
Note: <\/strong>Unlike the wide range of other command-line programs from Windows\/DOS, nslookup has the case-sensitive parameter \u201c-q\u201d. In other words, a parameter in which capitalization or lack thereof is relevant.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
