This shows us the DNS server that we’re connected to, then it also displays the DNS server and what its IP address is. If we simply type “nslookup” and hit enter, this is going to send us into an interactive environment. The first utility we want to look at is NsLookup. We’ll type cd / (backslash) so you have more room to work with. We’ll launch the command line utility by typing “CMD”. We want to use PING to make sure we can actually resolve the name.ĭemos on how to use the command line to test Name Resolution. That’s network connectivity, not Name Resolution. In other words, can we connect to you and do we get a response? What we are going to use it for is, can we resolve the name to an IP address? Whether we can connect to it or not is a different problem. The way to determine whether it’s there or not is by looking at the DNS cache. We will need to need to flush the IP address. Remember, if we’ve resolved an IP address for a specific hostname and that IP address changes, as long as it’s in our cache, we’ll go to the wrong IP address. We have the ability to flush our DNS cache. We also have the ability in there to display my current DNS cache. One of the primary things we can do with ipconfig is we can register my computer with DNS. You will see the different switches later in the demo. We have a non‑interactive mode where we’re looking for just a single piece of information. we enter into a series of a caret where we can get more details in. We have an interactive mode where we just type NsLookup. NsLookup allows us to do a lot of things. The first one is our command‑line utilities called NsLookup. We can troubleshoot using Command‑Line utilities, PowerShell utilities, and then Linux utilities. We’re going to see there’s multiple different utilities that we can use. We have to be able to troubleshoot why Name Resolution failed. This content is from our CompTIA Network + Video Certification Training Course.
