DNS refers to Domain Name System. It is a system that translates domain names (like google.com) into IP addresses (like 74.125.224.72). Without DNS, you’d have to remember every single IP address of every site you wanted to visit, which would be pretty inconvenient and challenging!
DNS is a vital part of the Internet. It’s like an address book for websites and servers, which allows you to connect to them by entering their domain names instead of IP addresses.
Why should you care about your DNS settings?
DNS settings are essential for your website. If you have a domain name, it is necessary to correctly configure the DNS settings to avoid your site’s problems. It might hamper your brand’s value as well as an image if not checked properly.
DNS leaks are dangerous as they can expose you to malicious websites and malware. When your computer uses an external DNS server, it may be able to access sites that have been blocked by your ISP or company firewall.
It also means that any information you enter into those sites will be sent through the unsecured connection provided by a third-party DNS provider. Malicious hackers could intercept this data and steal passwords, credit card numbers, etc., which would put your personal information at risk!
How to fix DNS leaks?
DNS leaks can prove to be harmful to your business and customers. You can use various methods to fix those leaks. Some of them are mentioned below:
- Use a VPN that has its own private DNS servers. This is the best method as it will prevent any leak from happening in the first place, and you can be sure your ISP won’t know what sites you’re visiting or what content you’re downloading/ streaming.
- If your VPN doesn’t have its own private DNS servers, use a third-party service like Google Public DNS or OpenDNS. To do this, simply change your primary and secondary DNS servers. You may also want to disable any other options such as “Use Primary for WINS Resolution” or “Enable NetBIOS over TCP/IP.”
- Disable IPv6 completely on all devices connected to your network (this includes both wired and wireless connections). IPv6 is not compatible with most VPNs at this time, so it’s best just to turn it off completely until there’s more support for it.
- Disable any Internet Connection Sharing (ICS) features on your router. This is usually found under the Advanced tab of your network adapter properties window in the Windows Control Panel.
- If you’re using a wireless connection, disable “Wireless Network Discovery” and “File and Printer Sharing for Microsoft Networks.”
- If you’re using a wireless connection, disable any features that automatically connect to open hotspots (such as “Connect to Open Hotspots”). These settings are usually found under the Wireless tab of your network adapter properties window in the Windows Control Panel.
- Use a wired connection whenever possible. Wired connections are always more secure than wireless ones because they don’t broadcast your activity over radio waves, which anyone can intercept.
However, the best way to fix DNS-related issues is to deploy a DNS checker into your system.
What is DNS Checker?
DNS checker or tester can help you find out if your DNS settings are correct, as well as diagnose problems with your connection. It is a tool for checking the status of the following DNS records on your domain:
A – Host Address Record (IPv4)
AAAA – Host Address Record (IPv6)
CNAME – Canonical Name Record (Alias)
MX – Mail Exchange Record (Mail Server)
NS – Name Server Record (DNS Provider)
PTR – Pointer Record (Reverse DNS)
SPF – Sender Policy Framework Record (Anti-Spam)
SRV – Service Record (Application)
TXT – Text Record (Freeform)
DNS records are the glue that holds your domain together. If they are missing or incorrect, you will experience problems with your website and email.
DNS Checker tools can check the health of a domain name from anywhere in the world. This is quickly done by using a VPN service that allows you to connect to servers all over the world. There are many different types of DNS checkers available online. However, not all DNS checkers offer the correct functionality and features to make it easy for users to test their connections and resolve any issues they may have with their network setup.
The best way to choose a good DNS checker is by reading reviews written by other users who’ve tested the product before you buy it. You should also consider what kind of tests each tool offers to know exactly what type of information will be provided once you run a test on your computer or mobile device.
Must-have features of DNS checker
Select an efficient DNS checker so that you can easily keep track of your DNS servers and fix the leaks. You must choose DNS Checker that has the following features:
- Global DNS Testing: No matter where your DNS servers are located and how many servers you are using, you should choose a DNS checker that can ensure that everything is in order.
- Check Serial Number: DNS Checker must be able to efficiently monitor changes in serial numbers of your DNS servers to assure that no DNS server is missed.
- Support both Ipv4 and Ipv6: Whether you host your websites on IPv4 or IPv6, your DNS checker must allow you to check both your servers.
- Download reports: You must be able to download detailed DNS reports and compare them with previous ones with the help of your DNS Checker.
Wrapping Up
There is a need to deploy a DNS Checker to your system as it is a handy tool for checking the status of your domain name. It will help you check whether your domain names are registered correctly or not. If there is any problem with the DNS records, it will show you an error message and tell you what problem has occurred.
DNS Checker can help your business to keep growing and building trust and loyalty.
Keep your DNS servers bugs-free!
