4 Useful DNS Tools You Should Use

Check out these 4 DNS tools everyone should use to make their lives a little less stressful (like that’s even possible). These tools are great for people that are trying to see if their No-IP hostname is resolving correctly.

To use these tools you will use the Dig command in terminal (Mac) or the command line (PC).

Dig is an acronym for “domain internet groper”.  Dig is a useful tool for webmasters and system administrators, it can be used to query DNS servers and fix DNS related issues.  Dig is a part of the BIND DNS software.

Check out these 4 useful DNS tools you should use:

1. Whois

Whois is an easy way to find information on the owner, nameserver, registrar etc. of a domain name. It is useful for getting all the detailed info you want from a domain, assuming the domain doesn’t have private registration enabled.

The Whois command can help you identify the responsible party for a domain. This is useful if you have problems sending to, or receiving from a domain; or if you just want to query the authoritative nameservers for that domain. To use these tools, open up Terminal on your Mac, or command line on your PC.

Type “Whois” followed by your domain of choice and hit enter.

Then type Whois mashable.com and hit enter. It will bring up all of the domain registration information.

2. Ping

Ping checks to see if you can actually reach a server. It is the go to command for making sure that a server is online and functional. You can also use this tool to see if a website is down for every one, or just you.

Type “ping noip.com” and hit enter

To stop this command hit “Ctrl + C”. Ping is a simple way to check if your domain name is resolving correctly.

3. Dig

Dig is a great way to get check records for a domain like A, MX, TXT, PTR and other advanced DNS records. We have done quite a few extensive Dig tutorials. We love Dig!. Check out this Dig tutorial for some cool ways to use it.

You can use Dig to lookup nameservers. NS lookup is useful for quickly looking up name server information, but it usually requires detailed parameters.

Type “dig noip.com ns” and hit enter.

This command will show all of the nameservers associated with noip.com.

4. Traceroute

Traceroute shows you the route (path) that was used to connect you to the IP address or hostname. It will show all of the routers it goes through until it gets to its destination, or it fails. A traceroute also tells you how long each hop to each router takes and if it fails, it will show you exactly where the IP packet failed. Our support staff uses it all of the time to help customers figure out if their hostname is resolving to the correct IP address. This guide will show you how to run your own trace route.

Are You Making These 3 Costly Managed DNS Mistakes?

Are You Making These 3 Managed DNS Mistakes?

1. Not having a backup hosting provider. Do you manage your DNS internally? Do you have a backup hosting provider? If your primary host goes down, a second hosting provider can still divert your traffic to the right place. (Just make sure your offline settings are directed to a different IP address)

2. Not monitoring your DNS for downtime. If your site goes out at 2am, will you know immediately, or will you have to wait until 9am when a customer finally calls in to ask whats up with your website? 5 minutes of downtime isn’t good, let alone hours! With server monitoring, you will get a notification the second something goes wrong with your website. Be sure to monitor your web services with No-IP.

3. Not having failover support. What if your website does go down? So, you get a notification that it is down, but what will you do? If you have failover support, your traffic will automatically be diverted to another IP address, web site, or to a custom web page stored on our servers. When your service comes back up online, we will undo the failover settings and normal operations will continue. Your website won’t miss a beat and your CEO and customers will stay happy. How does the failover service work?

If you are making any of these mistakes, it’s time to think about solutions that will help resolve them. The last thing you want to do is worry about failover support or a backup hosting provider at 2 in the morning when your website is down and your international customers can’t reach your website. Learn more about all of the services that No-IP offers.
