The Ping command is a great little utility tool with a simple command-line interface that serves for network diagnosing or, more precisely said – to probe a particular host or IP address (IPv4 address or IPv6 address) and see if there is a connection to it.
With the Ping command, you are sending packets of data using the ICMP (internet control message protocol) from your device to a target. The packets will be 4 by default, each with a 32-byte size, and you will get the time it took each of them to reach the target. Another useful part of the statistics is that you will get minimum, maximum, and average time (in milliseconds) for the road. An interesting detail is that you will see a percentage of lost packets. You will also get the IP address of the target.
DNS records are small but very important elements for the Domain Name System (DNS) to operate properly. There are different DNS records to accomplish specific functions. The A record and AAAA record are essential to translate domain names to IP addresses. Yes, you got it! Without them, the Internet experience wouldn’t be as comfortable as it is now.
What is the purpose of the A and AAAA records? – Quick review
The A and AAAA records are very important to access domain names. Both DNS records are directly involved in the DNS resolution process. When a user requests a domain name, this action triggers a process to search for the corresponding IP address of the requested domain. Without the IP address, the content of the domain can’t be loaded.
For instance, a user requests domainexample.com, so the resolution process gets triggered until it gets its corresponding IP address 22.214.171.124. At that moment, the domain is loaded so the user can access it.
And this key process is driven exactly by the A record and the AAAA record.
Is a Free Monitoring service something we should be concerned about? Yes, it is correct. Why? Because if something goes wrong with your internet business, this feature will notify you. This can help you avoid losing a lot of money and potential consumers if your site is taken down. So, let’s see what the Free Monitoring service’s main objective is and where you can discover it. But first, let us define what the Monitoring service implies.
What is the purpose of the Monitoring service?
The Мonitoring service is a must-have feature. It provides a wealth of information about the status of your servers, which you use for web, email, DNS, and other purposes.
It allows you to keep track of the status of your servers in real-time. You’ll be able to notice issues like a component failure or extremely slow traffic if you continually monitor your network. Furthermore, if an issue arises, a service like this will warn you automatically by email, text, or another mechanism such as webhooks.
Overloaded routers, server failures, and network connectivity issues are all detected by the Monitoring service.
Dynamic DNS is another name for Dynamic Domain Name System(DDNS). It’s a great way to update your name server automatically and on a regular basis. It changes IP addresses, as well as their corresponding A (IPv4) and AAAA (IPv6) records, whenever they change. It saves you the time and effort of manually doing this process.
Internet Service Providers (ISPs) are constantly changing customers’ IP addresses. As a result, they face significant difficulty ensuring that they do not run out. Every device that connects to its network needs a unique IP address.
Anycast DNS is a great mechanism for traffic routing. It distributes content through several nameservers that store one identical IP address.
Each one of the servers is positioned in various locations all over the world. That way, they are a lot closer to the potential users. All of this is for providing a better and faster response to the requests and an excellent user experience.
When a user requests a particular website, the server that is nearest and available is going to answer the query. So, the chance of experiencing any latency is reduced to a minimum. Your customers are going to e able to reach and connect to your website easily.
Distributed Denial of Service (DDoS) is a cyber-attack that aims to disrupt its targets, such as s system, server, or network. It floods them with large amounts of traffic arriving from multiple devices. The many different sources used to attack the victim are the reason why it is called “distributed”. The target is down, and a denial of service occurs that doesn’t allow any user to connect with it.
DDoS attacks could be initiated in different ways, and techniques vary or even can be mixed in order to hit the target stronger. Overall, every DDoS attack runs by infecting as many devices connected to the Internet as possible. In addition, it could be performed globally with one main goal to flood the target with massive traffic from all of the compromised sources such as IoT, servers, computers. The target is not able to handle the traffic and becomes sluggish until it is completely drowned.
The CAA record is considered not so well-known in comparison with, for example, the DNS A record. Actually, the CAA record was first defined in 2013, and from 2017, Certificate Authorities are obligated to first examine it before issuing some type of certificate. So, let’s reveal a little bit more information about it.
The CAA record explained
The Certification Authority Authorization record, or for short the CAA record, is applied mainly by the DNS administrator of a domain to add and establish which Certificate Authorities (CAs) can publish SSL or TLS certificates for the domain.
As a domain owner, you have the right to pick which CA can distribute cryptographic certificates for your domain name.
The purpose of a cryptographic certificate is to authenticate the domain owner plus to secure the communication with that domain with encryption. Additionally, it keeps data that is considered sensitive safe.
With the CAA record, the domain owner holds the advantage of having control over the method of issuing certificates. Moreover, the number of miss-issued certificate for that domain is going to be reduced. It is possible to use CAA record for your complete domain or only for some of the subdomains. It all depends on what are your personal preferences and the setup you want.
A well-known requirement for applying CAA records is first to enable DNSSEC. The reason for that is basically providing better security and assurance from the side of the CA.
There are multiple types of DNS servers – Primary, Secondary, Authoritative, Recursive, etc. . They accomplish different functions for a network to perform properly. Specifically, DNS servers are organized, obeying a hierarchical order. Today let’s talk about the Primary DNS server and what functions it has in the system.
What’s a Primary DNS server?
The Primary DNS server is also named the Master DNS server because it is the source of the original data. The Primary DNS servers are in charge of hosting the zone files that store DNS records of the different domains.
In the process of gaining knowledge about Domain Name System, it is essential to clarify the meaning of the DNS CNAME record. We just can’t skip it. So, let’s explain a little bit more about it.
What is a DNS CNAME record?
The complete name of the DNS CNAME record is a canonical name record. The Canonical Name is showing which specifically is the actual name of a domain. It has its main goal. It is to point the true canonical domain name of one domain name.
The DS record is not one of the most common DNS records. It is used with DNSSEC and to keep the chain of trust between the parent zone (TLD level) and the one you manage. Do you what to know how exactly the DS record works? Here we go!
Owning a business website requires a lot of strategies and effort to attract people’s interest. Sometimes is not about getting complex ideas but going to the basics. Customers and search engines so appreciate security. It’s a value directly linked with reliability and a good reputation. Besides being an obligation, it can really bring benefits to your business.
Let’s dig a bit into 4 SSL certificate types for your website. One of these should be suitable for your site.
