• How To Find Dns For Ip

A simple way to test your internet connection is to ping Google.com – the Ping network command is built into all versions of Windows.

The bottom half of the “Internet Protocol Version 4 (TCP / IPv4) Properties” window shows the DNS settings. Select the “Use the following DNS server addresses” option. Next, type in the IP addresses for the preferred and alternate DNS servers you want to use. Here are the IP addresses for Google DNS and Open DNS: Google DNS. This article explains the step by step process of how to change DNS servers IP addresses in Apple macOS High Sierra. We use Google public DNS servers in this example, while you can use any reliable DNS. Step 1 – Open Network Settings. Click on the Apple icon on the top left corner of your Mac and go to “System Preferences” option. Click DNS, then click the Add button at the bottom of the DNS Servers list. Enter the IPv4 or IPv6 address for the DNS server. Below is a short list of commonly used public DNS servers. Secondary DNS servers can be added to add a layer of redundancy. MAC, IP, and DNS addresses are some of the most commonly used terms. Knowing their details would help you when you are setting up a new router or troubleshooting network issues.

This command tests whether you can reach a particular website – it also measures the round trip time to receive a reply from that website.

Ping is an ideal way to check if your actual internet connection is faulty – if you have problems web browsing it may be an issue with your web browser, not your broadband connection…

When reporting a fault to your broadband provider, you may be asked to ping Google to test if you have internet access – so it helps to know how to do it.

Ping Google.com

The Ping command is run from a Command Prompt window – to open it:

Mac Get Dns Server

XP – Click ‘Start’ then ‘Run’ and type CMD into the ‘Open:’ text box then press ‘OK’ to open a Command Prompt window.

Windows 10, 8, 7 and Vista – Click the Start button (not required in W10) and type CMD into the ‘Search’ text box then click on the cmd.exe or ‘Command Prompt’ program/desktop app at the top of the search results to open a Command Prompt window.

• Type ping www.google.com then press Enter to ping Google (you can ping any other website in the same way). Note that you can use either www.google.com or google.com

After a few moments you should see some responses, similar to this:

What Do The Ping Test Results Mean?

The ping command sends 4 small ‘packets’ of data to Google – each packet asks Google to send it back if they received it ok. We can see in our example that all 4 requests did reach Google successfully because we got 4 Replies – so we know our internet connection is working.

This is summarized at the bottom of the results: 4 packets Sent, 4 Received, 0 Lost (0% loss) i.e. no packets lost in transit.

The test also shows how long it took for each packet to reach Google and get a Reply back. The ‘time=’ value next to each reply is measured in ms (milliseconds) and lower numbers are better (quicker).

This is summarized at the bottom of the results: Minimum = 23ms, Maximum=24ms, Average=23ms

The ’round trip’ reply time is often called ‘lag’ and is particularly important for gamers (when super-quick responses can be beneficial).

A time of 20ms to 60ms is very quick (good broadband), over 250ms is slow (typical of satellite internet) and over 1000ms is very slow – not suitable for gaming but common with slow mobile broadband.

Ping Google.com Continuously

Instead of pinging just once (which sends 4 requests to the website), you can run a continuous ping by simply adding a space followed by -t to the end of the original command:

• type ping www.google.com -t then press Enter

This command will send continuous ping requests (not just 4) so you should receive a constant stream of Replies that scroll down the window – this is very useful for testing if your internet connection is intermittently faulty:

Keep an eye out for error messages and also check that the ‘time’ in ms stays fairly consistent (it should do if your internet connection is good).

• Press CTRL and C when you want to stop the continuous pings

Tip: it is not nice to constantly ping a website for hours as it uses up a tiny bit of the website’s resources. We used Google in our examples because they are so big that your pings won’t matter, but they might do to a small website.

Common Ping Test Error Messages

Because 4 requests are sent to the website, you may see these error messages repeated up to 4 times – once for each request.

• “Request timed out” – either your network/internet connection is faulty or the website you pinged is itself having problems

Try pinging a few other sites to test if the problem is with that specific website or with your network/internet connection.

• “Ping request could not find host www.google.com … etc” – either your network/internet connection is faulty or you pinged an incorrect website name or there is a DNS fault (see next section below)

Check spelling or try another website e.g. ping www.yahoo.com

Ping An IP Address

It is also possible to ping an IP address, rather than a website name – this is a good way to rule out a DNS (Domain Name System) fault.

Choose either of Google’s Public DNS servers – 8.8.8.8 or 8.8.4.4 as they are the most likely to be constantly available. In the Command Prompt window:

• Type ping 8.8.8.8 then press Enter to ping the Public DNS server

If you still get an error then there is not a DNS fault and you have no internet access – most likely your network/internet connection is faulty. Try to reset Windows internet settings to fix any network configuration errors.

Conclusion

How To Find Dns For Ip

Ping is a useful first step in troubleshooting possible ‘internet’ issues – if you receive replies with no errors from a range of websites then you know that your internet connection itself is working ok.

If so, any issues with web browsing are more likely to be due to a faulty web browser (try a different one) or perhaps a firewall issue (temporarily disable it).
