Default TTL – Refers to how long a record is cached before it’s refreshed.Expire – Secondary DNS cache expiration time.Rety – If a primary server doesn’t respond to a request, it will reconnect within this timeframe.Refresh – The time a secondary DNS server will take to request new information if a primary server’s serial number has changed.Serial – This is the serial number of the zone file.Responsible mail addr – Represents the email of the domain administrator.This applies even if you start verifying records for another domain. After the initial nslookup command, you can run set commands for each record. Tip : If you’re checking multiple record types, you don’t need to type “nslookup” for each one. In the screenshot below, I performed a lookup for MX, PTR, and SOA records, but of course, you aren’t limited to only those. You can address any errors or issues you discover from this information quickly. This process is the same as the above example, but this time, you’ll specify which record you want to query.

This is the same as the above example, just in-you guessed it-reverse:Ĭ:\Users\username>nslookup 162.243.68.201 Set Command If you have an IP address and need the domain name, you can do a reverse DNS lookup. The reason it says “non-authoritative answer” is because I’m using a recursive server for the query. ![]() In response, I received the IPv6 and IPv4 address for the domain. In this example, I did a simple request for the IP address for DNS Made Easy. Nslookup can also provide information on DNS records for your domain.Īn nslookup command would look like this: C:\Users\username>nslookup It can find the IP address of a host or perform a reverse DNS lookup (to find the domain name of an IP). This command is comparable to Mac or Linux’s dig function. The nslookup command is helpful in diagnosing issues with DNS name resolution.

If you take the search route, you will see an option for Windows PowerShell and PowerShell ISE. Using the search option is where things differ. Instead of typing cmd, you would type PowerShell in the Search or Run Command window. You can access PowerShell in the exact same way as Windows Command Prompt. Boom, you’re in!

This means you can complete a series of cmdlets as opposed to only one command at a time. It features a scripting system, built-in administrative capabilities, and can run batch commands. This shell runs in a blue window and uses Command lets (cmdlets) instead of CMD or MS-Dos commands. PowerShell was first released on Windows in 2006. With this tool, you can run single-line commands.

You probably skipped this part and went straight to the commands. It also touches on the differences between the two shells. This resource covers useful commands in Windows Command Prompt and PowerShell. Luckily, computers have a built-in utility that can help you do just that. From simple to complex configurations, there are times you need to check on how your DNS is behaving.
