Purchasing a Premium DNS service will undoubtedly include features and administration tools. Let me outline what you might anticipate when you acquire a premium DNS service.

Here are some more advantages you’ll undoubtedly enjoy:

  • Better security
  • Redundancy and quick performance
  • DNSSEC
  • Advanced Analytics & Reporting

How do you know if the Premium DNS service is right for you?

The actual needs of your company will determine the answer.

You might be able to get by with a free DNS service if you run a small or local business, a start-up, or a blog and your plans call for a moderate amount of domestic traffic. A reliable domain, the bare minimum features needed to host the website, and average performance are all included. Not bad—at least to begin with. Success can take you by surprise and expand more than you anticipated. Your requirements will then increase, and Premium DNS will be appropriate.

The benefit of continuous uptime is completely understood if, on the other hand, you manage a worldwide company with heavy traffic. You will make money if you can satisfactorily respond to millions of global queries. Downtime, slowness and lengthy loading times are unaffordable. The most outstanding level of security is required to safeguard user data and transactions. You should use Premium DNS!

Conclusion

In conclusion, Premium DNS is an added future that might be incredibly helpful for your company. You get more protection, your website loads faster, and it offers a DNS Failover solution if your website goes down. Doesn’t that sound great? Therefore, don’t waste any more time and utilize this fantastic service.

How does DNSSEC add an additional level of security?

DNSSEC is the most effective technique to secure your Domain Name System. We’ll explain why, what the phrase implies, and how you can benefit from it in this article. So, let’s keep it going.

The explanation of DNSSEC

DNSSEC is a collection of Security Extensions for the DNS that adds authentication and data integrity.

The Internet Engineering Task Force (IETF) invented it in the 1990s. Its primary goal is to provide an authentication method that uses digital signatures and public cryptography to prove the data’s origin. The data owner can use its private key to sign DNS data (DNS records) and ensure that the information is secure. Each recursive server can validate the data’s origin by comparing it to the public key.

It’s a complete chain of trust, beginning with the root server and ending with the exact hostname. Except for the root zone, which has nothing on top of it, each zone is signed by the one above it.

If the recursive server cannot authenticate the data for some reason, it will discard it and try again. It’s always better to be safe than sorry.

Is it advantageous?

The importance of DNSSEC may be summed up in two statements:

  1. You can ensure that the DNS data (DNS records) has not been tampered with by using DNSSEC. Consider what would happen if a cybercriminal modified DNS records on the route to the customer. The client can obtain a modified version of the product. A record that points to a server under the lousy actor’s control. There is a risk that the client’s data will be stolen. As a result, DNS cache poisoning is less likely. 
  2. Authentication of DNS data from a source. You can be sure that the data comes from a legitimate source and that the authoritative name server is valid using DNSSEC. It will prevent any bogus server forecasts.

Where can you get DNSSEC?

DNSSEC is not set up automatically. It is, however, straightforward to set up. As a result, most DNS hosting companies include it as a standard feature.

A substantial number of domains do not support DNSSEC. However, their entire worth is negligible. It can be used by well-known generic top-level domains (gTLDs) and country-code top-level domains (ccTLDs).

Simply enable it in the control panel of your DNS hosting provider to get started. Then look for DNSSEC and click “enable” for each DNS zone you want. After that, you’ll get a DS (Delegation Signer) record, which you should point to your domain’s registration information.

Conclusion

The decision to adopt DNSSEC to maintain DNS security is a wise one. Nowadays, cyber threats and direct DNS attacks are commonplace. Of course, DNSSEC is expensive, but you already know that the cost of preventing a criminal attack is always less than the cost of repairing the unintended consequences of a criminal attack.

Interesting DNS Terms & Definitions

Here are some interesting DNS terms you may not know yet. They are helpful both for beginner DNS administrators and more advanced ones. 

Dynamic DNS

Dynamic DNS automatically updates your IP address every time it is replaced. The Internet Service Providers (ISPs) are commonly changing it since it is easier for them to manage their large networks. For that reason, it is really useful to implement Dynamic DNS, for example, for your CCTV cameras for surveillance.

Anycast DNS

If you want to boost the DNS resolution process of your domain, you should consider Anycast DNS. It is a routing mechanism that works by placing one IP address into several name servers that are positioned in different points of the world. That way, the DNS request (DNS query) takes the shortest path, and the closest server provides the needed data.

DNSSEC

DNSSEC (Domain Name System Security Extensions) brings extra protection to your DNS (Domain Name System). It applies cryptographic authentication for the DNS data (DNS records) that goes around the Internet. Besides, it provides insurance for the origin of the DNS data and its integrity. 

DNS query

DNS query is the process of searching DNS data (DNS records). Usually, that is the IP address (A record or AAAA record), but it could be a different DNS record of a domain name. DNS queries are initiated by users every time they want to visit a specific website. The DNS resolver (Recursive DNS server) receives the DNS query and asks for the needed information from the Authoritative DNS servers.

DNS server

The DNS servers are two types:

Authoritative name server: It replies to DNS queries. It is a source of reliable data, and it doesn’t just contain cached replies from another name server. Moreover, it is able to answer requests that are related to domain names registered in its configuration system.

Recursive name servers: Its main goal is to receive the user’s DNS query and look for the desired information. They ask many servers until they find the answer. Typically, they are described as the link between the user and authoritative name servers.

DNS cache

The DNS cache is a method for saving the DNS records for a particular amount of time of the already requested domain name. It is a widespread method included in different devices, like computers, tablets, mobiles, and DNS resolvers (Recursive DNS servers). Its primary purpose is to minimize the amount of time for resolving a domain name. Moreover, it simplifies the assignment of the Recursive DNS server by reducing the number of complete DNS lookups for a precise domain name.

DNS propagation

DNS propagation is the amount of time required for spreading the new DNS information (DNS records) you made through the rest of the network. Let’s say you adjusted your A or AAAA record and replaced the IP address of a hostname, which should be distributed to all of the recursive servers. The process of DNS propagation could take from one hour up to 72 hours. 

Conclusion

So, now you know some very interesting and helpful DNS terms. For sure, they are going to help you improve the management of your DNS.
