Using the Secondary DNS to preserve a trustworthy copy of your data is an excellent idea. We’ll look at why and how in this article. But first, let’s learn about what the Domain Name System is for.

Domain Name System (DNS): What does it mean?

DNS is a naming database system that locates and converts Internet domain names into IP addresses. Consider it like a directory or, more recently, your phone’s contacts list, where names and phone numbers are correctly matched.

The DNS directory is distributed globally and operates daily, assisting in searching and reaching millions of existing domain names.

Secondary DNS explanation

Secondary DNS is a service that you can use in addition to your Primary DNS. It provides an additional network of name servers for keeping copies of the zone file containing your domain’s DNS records. These servers can duplicate the Primary DNS zone file for your domain and give additional points of presence (PoPs). Users will be able to resolve your domain much faster this way, even if your Primary DNS is unavailable! Isn’t it fantastic?

Backup DNS or Slave DNS are other names for the Secondary DNS service. It’s also important to note that because it just saves copies, it doesn’t allow modifications to DNS records. You can only make changes to your Primary DNS.

Why is Secondary DNS advantageous?

There are four fundamental reasons to set up a backup DNS server:

  1. You will enjoy complete uptime. Users will be able to access your website using the backup DNS even if the Primary DNS goes down. If you’re in the e-commerce industry, you understand how critical uptime is to your bottom line.
  2. Make sure you have a solid backup plan in place. This is a wonderful backup option if something goes wrong with the Primary DNS. Backup DNS will duplicate your DNS records for you.
  3. Check to see that your Primary DNS server isn’t overburdened. You will be able to distribute the load and assure the availability of DNS records if a large number of inquiries are received.
  4. In the case of failure, malfunction, or attack, the sheer existence of a Primary DNS server carries danger. The authoritative records for the DNS zone will simply be unavailable. Secondary DNS is a fantastic approach to avoid dealing with this issue.

Conclusion

You now understand why Secondary DNS is critical for you and your company. These benefits are not only for being read but also for being experienced. Using Secondary DNS to protect your domain is a good idea. Make sure nothing is preventing your DNS from resolving. There will be no sales lost if you have 100 percent availability. So go ahead and do it!

Are you wondering about learning more about the Monitoring service? If yes, you are in the right spot. Why? Because in this article today, we will explore and take deep into its primary purpose, general types of checks, and the main advantages of the Monitoring service. So, don’t waste any more time, and do it!

What is the definition of a Monitoring service?

Monitoring is essential for providing stable service and a pleasant user experience. It also aids in the detection of issues with your services, such as web, DNS, and email. It also gives you detailed information about the state of your servers and aids you in swiftly finding and resolving problems.

You may also monitor and keep track of the status of your servers in real-time. Any problems, such as a component failure or excessively slow traffic, will be easy to spot and address.

The Monitoring service can also send out automatic notifications. As a result, you will be notified if a problem arises via email, SMS, or other means.

General types of checks

You’ll be able to do various types of checks relying on your Monitoring service. However, there are a few types that you should be aware of:

  1. Ping (ICMP)

It allows you to see what is going on in the network for a given domain or IP address. It does ICMP ping checks on a given IP address. For example, if 50% of packets fail,

  1. Website HTTP(s)

The system sends HTTP(S) queries to a certain website or IP address. It guarantees that the URL response code is 200 and marks it as UP in this manner. So, it marks it as DOWN if the answer code is different. You can change parameters like the hostname, port, and path.

  1. User Datagram Protocol (UDP) 

It checks the IP address for the selected UDP port number. It indicates the connection as UP when it is successful. When a connection fails, it is also marked as DOWN.

  1. TCP (Transmission Control Protocol) 

It establishes a TCP connection to a specific IP address (IPv4 or IPv6) on the specified port number. It indicates the connection as UP if it is successful. If the check is failed, however, it is reported as DOWN.

Advantages of implementing Monitoring service

You can get the following benefits by using the service:

  • View the system’s current and historical performance.
  • View the most recent and previous system alerts and occurrences.
  • Create reports using pre-formatted templates and data from the system.
  • Create custom dashboards and views.

Conclusion

By way of conclusion, we can absolutely agree that Monitoring is a must-have if you want to be much safer. Furthermore, it is critical for your business to run effectively and without problems. It prevents outages, improves visibility, and pinpoints problems. So why not try it? Best of luck!

Are you searching on the web about TCP vs UDP? If the answer is yes, you are on the right article. Why? Because today, we will explore the TCP, UDP, and their main difference. If that answers your search, let’s start this adventure.

TCP – Definition

The Transmission Control Protocol (TCP) is a data transmission standard used by software programs. It’s designed for efficiency rather than speed. Data packets might get lost or arrive out of sequence in data transfer. TCP ensures that every packet reaches its intended destination and, if necessary, is reconfigured. TCP will request the retransmission of lost data if a packet does not reach its goal within a defined interval. It is in charge of the connection between the two programs. This occurs throughout the conversation. The purpose is to make sure that both parties send and receive everything that has to be sent and that everything is correct. TCP is a widely used network communication protocol.

What exactly is UDP?

The User Datagram Protocol (UDP) is a communications protocol that allows devices and networks to communicate with one another. Its primary and most appealing characteristic is its high-speed connection.

It’s a valuable protocol for tasks that require a lot of time and speed, such as DNS lookups or video transfers.

UDP was first introduced in 1980, and it has remained a vital component of the Internet’s productivity toolset ever since.

TCP vs UDP – Comparison

So, we’ve arrived at the subject of our article: TCP vs UDP. You now have a basic understanding of the Transmission Control Protocol and the User Datagram Protocol. Let’s have a look at the fundamental distinctions between them.

  • Type of service. On the other hand, TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol.
  • Reliability. Because it secures data delivery to the destination gateway, TCP is trustworthy. Data delivery is not guaranteed via UDP.
  • Speed. The comparison that follows is based on speed. Contrary to TCP, which is slower, UDP is somewhat faster, more straightforward, and more efficient.
  • Resubmission. The User Datagram Protocol does not allow for data packet retransmission. The only protocol that allows this is TCP.
  • Protocols. TCP is used by HTTP, HTTPs, FTP, SMTP, and Telnet. On the other hand, DNS, DHCP, TFTP, SNMP, RIP, and VoIP all use UDP.
  • Information flow. TCP allows data to travel both ways, making it a full-duplex protocol. On the other hand, UDP is best suited to unidirectional data transmission.

After learning the differences between TCP and UDP, you might be asking yourself, “Which one should I choose?” Because they are both ideally suited to specialized applications, deciding between UDP and TCP is simple. TCP is the way to go if accuracy and dependability are critical. If speed is a priority, UDP is the way to go.

Conclusion

So, which protocol is favorable: UDP or TCP? It all relies on what you want to do with them, as it does in any case. UDP must be used if you need a quick and consistent data transmission for a program to function correctly. On the other hand, TCP is a robust and reliable protocol for transporting data without losing any of it.
