3 Reasons to Upgrade to Premium DNS service

Premium DNS service is a great choice for everyone who wants to take their online business to the next level. It is normal to wonder should you update to such type of service or not. Let’s explain a little bit more about it.

DNS service – What is it?

The Domain Name System, or for short DNS, is a global network of name servers. The main purpose is to show where domain names are and link them to the corresponding IP addresses. Additionally, the DNS could have features such as connecting hostnames to other hostnames, further instructions about services, verifications, and more.

Therefore the DNS helps to orientate all your users, guide them to the proper addresses or different hostnames.

There are several questions that will help you decide if you need a Premium DNS service:

  • How many users connect to your site?
  • How frequently do they connect?
  • Do you have worldwide visitors or nearly all of the users are from your country?
  • Do you want some extra security features? How critical is it for you to keep your visitors safe?

What is DNS cache?

The DNS is the world’s address book that makes possible the current Internet. It is a well-recognized name system that connects domain names and IP addresses. The system is decentralized thanks to the DNS delegation, and it is separated into various DNS zones, but it is still very busy. To lower the traffic, we use a method of saving temporary DNS records called DNS cache.

What is DNS and how does it work?

The DNS is the reason why the Internet is even possible. It is the backbone. It is the one that facilitates the connection between hostnames, services, servers, IP addresses, and more. The DNS is a complicated, a bit old system that we use hundreds or even thousands of times a day.  

What is DNS?

DNS means domain name system. It is a hierarchy directory, where hostnames (domains) match IP addresses (numbers). It is the so much needed translator between us, the humans and the machines – servers.  We use easy to remember names that finish with TLDs (top-level domains like .com). Computers, on the other hand, work with IP addresses (like 130.211.0.0). 

DNS elements

  • DNS record. The DNS records are small text files that serve a specific purpose. The A record, for example, connects domain names and IP addresses. There are plenty of DNS types.
  • DNS query. Each query searches for a DNS record. The query starts from a device and hops from a DNS server to another until one can resolve it. 
  • DNS authoritative server. This is the primary server that has the zone file. It could be further away from the users, but it will have the most up to date data. 
  • DNS recursive server. This one is kind of a middle man. It has a cache memory where it can save DNS records. The recursive server will save the information from the moment a DNS query gets successfully answered and passes through it until the moment the DNS record gets too old (depends on the TTL value). Such a server searches for the DNS records if it does not have it.

The 4 most famous DDoS attacks in the history

Cybercrime costs billions of loss every year. Unfortunately, Distributed Denial of Service (DDoS) attacks are a plague that targets all kinds of victims: profit and non-profit organizations, international ventures, new entrepreneurships, and more. Your business can be the target. One day, you just experience traffic loads with weird behavior. All your online services (website, email, etc.) work so slow or get totally stopped and inaccessible.

DNSSEC – Why use it?

Do you already know what DNS is? Recently I talked about it, so now we will explore one of its problems, security. The DNS was created almost 50 years ago when the internet was young and small. Now we need to patch it, and here it comes, DNSSEC. DNSSEC is the fix that could sustain the security of all the information going around.

Top 6 DNS record types – list

There are plenty of types of DNS records. More than 50 types of DNS records (for example CNAME, ALIAS, AAAA, etc.) are still in use, and at least the same number is already absolute. You don’t need all of them all the time. Let’s talk about the essentials. The top 6 DNS record types that you can’t manage your DNS without. 

A Record

We can’t skip the A DNS record from any DNS list. It is probably the best-known record type. The purpose of the A record is to direct, to point a hostname to its IP address. When we talk about A record, the address is IPv4 (32-bit). There is a newer AAAA record type that uses IPv6 addresses (128-bit).
