DDNS or Dynamic DNS is a DNS service that can be useful to many. It is an automatic method for updating IP addresses that saves you from having a banned IP address that you can’t use or a paid static IP address, that might be very expensive.
If you’re looking for an explanation of IPv4, you’ve come to the right spot. We’ll look at its function, as well as its structure and how to check it, in this post.
IPv4 has been around since the early 1980s, can you believe it? It is the fourth version of the Internet Protocol, first released in 1981. Its goal is to establish communication norms, such as how data packets should be conveyed and how they must be received.
IPv4 has one distinguishing feature: it uses the best-effort delivery approach. It is not necessary to make any last changes between the two ends for the connection to work. Instead, you might try to send a message without waiting to see if it was correctly sent. That is why it is ideal for use on the Internet.
IPv4 addresses are short and straightforward. Therefore, they act as an identification card for any connected host.
Inexperienced and newcomers to the Domain Name System world frequently have questions about the Premium DNS vs Free DNS comparison. Can we only use the Free DNS, or do we need to apply the Premium DNS? In today’s article, we’ll take a closer look at these DNS plan types and what they offer. So, let’s begin.
This service provides the foundational DNS infrastructure that allows websites to function online. It is completely free.
If you own a website that does not yet have a lot of international traffic, Free DNS is for you. Start-ups, small or local businesses, and blogs, for example. Free DNS will provide you with a stable domain, average speed, and site management features.
Here is a quick guide to easily understand some of the DNS record types. All of them have a different role that is essential for the normal functionality of your Domain Name System (DNS).
Start Of Authority record or, for short, SOA record is crucial to explain this record before all of the rest DNS record types. It shows the beginning of the authority DNS zone. This DNS record contains very valuable data for the DNS zone. If you want your network to operate normally without difficulties, this DNS record is a must-have. It points to the primary DNS server. The SOA record keeps the information and contact details about the DNS administrator. It also holds several parameters, for instance, the domain serial number. Note that you should have only one SOA record per DNS zone.
We can’t skip mentioning the A record. Perhaps it is the most popular and well-known of all of the other DNS record types. It is also known as an address record, and its main goal is to link a hostname to its corresponding IP address. The A record is applying only for IPv4 addresses (32-bit). For IPv6 addresses (128-bit), there is a different DNS record – AAAA record.
Implementing the Secondary DNS zone is a great choice to keep a reliable copy of your data. Let’s make things a little bit more clear and explain more about it.
The DNS server is capable of holding a lot of zones to manage the DNS namespace more accurately. As a piece of that namespace is the DNS zone. It is a section that provides more organized and easy to control DNS components.
In order for your domain to work properly and accurately, you should have to point it to different servers, for example, mail servers, web servers, etc. To complete this task, you have to create multiple DNS records in the DNS zone.
All of your DNS records are going to be stored in the DNS zone. Furthermore, the existence of the Domain Name System is based on that one piece. The reason for this is that every part of it exists in a zone.
A DNS zone can be applicable for .com, example.com, info.example.com. However, if we examine a subdomain as a website on its own, that will need management on its own. This is because the subdomain could require a separate zone.
The DNS zone includes essential information about the DNS records, also contact information about the DNS zone administrator. It also contains zone parameters like Refresh and Retry rate described in the SOA (Start of Authority) record.
There are many different DNS records. Some are very specific. Others are common and exist in any DNS. SOA record is one of these common, always present DNS records. Let’s see what it does and why it is so important to have it!
SOA record is a key DNS record that indicates the start of authority. The authoritative name server (authoritative NS) is the top source of DNS information. It is the first DNS record that a zone file contains and sets the general properties of that zone. It also has more details about the zone transfers like the refresh rate, the retry rate, and who is administrating them (admin email).
Usually, DNS servers work together in a cluster. Those servers need to synchronize their zone file. For this purpose, they need to perform a zone transfer. The SOA works as a control record with a serial number and indicates the latest update. When the secondary servers (slaves servers) see that the number has changed, they will update and get the new data.
Now we will check one of the basic DNS records – CNAME. Why do you need CNAME records, how to use them, and are there any alternatives? You are about to find out!
CNAME, the “c” stands for “canonical”, and the rest is “name”. You can use it to show that one domain name is just another way of showing another domain (it is an alias for the canonical domain). The canonical means it is the “true” domain name.
When you have a business and plan to jump online, there are many critical decisions—the website’s design, logistics, strategy for promoting, and of course, choosing the best hosting solution.
There are a large number of hosting providers. You must know the objectives correctly and, therefore, your business’s real needs. The needs of a blog or portfolio site are very different from those of an e-shop. One will require so much more resources to manage more traffic, media files, etc.
Here you have some useful tips for choosing the best web hosting solution.
The DNS is magic, is essential, is the reason why the internet is possible!
It answers users’ queries of all sorts and finds the real addresses of the sites we love.
There is no doubt that we need it on a global scale, but do we need it for our websites? Yes! And the easiest way to get it is through a Managed DNS provider.
A Managed DNS service means that a DNS provider has created a system of name servers that you can use to host your DNS records and increase your site or application’s performance and availability.
You need DDoS protection because of the DDoS attacks, duh! With all seriousness, there are intentional cyber-attacks that hackers direct at websites or applications and use different weaknesses of the DNS. Those attacks are known as DDoS attacks, and you need special protection to keep your site afloat when they happen. Cause it is not a question of if, it is a question of when!
