What HTTP Error Codes Are?

Hypertext Transfer Protocol (HTTP) is the foundation of data communication on the World Wide Web. It defines a set of codes that indicate the outcome of a request between a user’s browser and a server. These codes, known as HTTP status codes, provide valuable information about the success or failure of a request.

HTTP error codes are three-digit numbers grouped into different classes. The first digit of the code specifies the general category of response, while the subsequent two digits offer more granularity. Understanding these error codes can be crucial for web developers and administrators, as they provide insights into what went wrong during a request.

5 Common HTTP Error Codes

  • 404 Not Found: One of the most recognizable error codes, the “404 Not Found”, indicates that the requested resource is not available on the server. This often occurs when a URL is mistyped, a page is deleted, or a link is broken. Users encounter a familiar “404 error” page, signalling that the content they were looking for could not be located.
  • 500 Internal Server Error: The “500 Internal Server Error” is a generic message that suggests something has gone wrong on the server side. It could be due to misconfigurations, programming errors, or other issues preventing the server from fulfilling the request. This error is a catch-all, indicating a problem that the server cannot specifically identify.
  • 403 Forbidden: When a server returns a “403 Forbidden” error, it means that the server understands the request but the server refuses to authorize it. This may occur due to insufficient permissions or authentication issues. Users attempting to access restricted areas without proper credentials often encounter this error.
  • 401 Unauthorized: Similar to the “403 Forbidden” error, the “401 Unauthorized” status code indicates that access is denied due to a lack of proper authentication. However, in this case, the server requires the user to provide valid credentials through an authentication mechanism like a username and password.
  • 400 Bad Request: The “400 Bad Request” error signifies that the server cannot process the request due to a client error. This could be caused by malformed syntax, invalid request message framing, or deceptive request routing. It’s essential to check the request parameters and structure when troubleshooting this error.

Why Are They Important?

Understanding HTTP error codes is crucial for both developers and website administrators. These codes serve as diagnostic tools, helping identify and resolve issues efficiently.

ICMP (Internet Control Message Protocol) is designed to facilitate communication between network devices, detect issues, and report them back to the sender. It operates at the network layer of the OSI model, making it an integral part of the Internet Protocol Suite.

Unlike protocols that actively engage in data transfer, ICMP is more of a silent observer. It doesn’t carry data like TCP or UDP. Instead, it sends error messages or information about network conditions. These messages, often referred to as “echo requests” and “echo replies,” are the foundation of one of ICMP’s most well-known utilities: the Ping command.

How ICMP Works: The Inner Workings

  • Echo Requests and Echo Replies

The Ping command, a familiar term for many, is built on ICMP. When you ping a device, you’re essentially sending an echo request. If the target device is reachable and operational, it responds with an echo reply. This simple yet effective mechanism is the heartbeat of many network troubleshooting processes.

  • Network Diagnostics

Internet Control Message Protocol goes beyond the Ping command. It serves as a diagnostic tool for network administrators, providing information about network connectivity, errors, and performance issues. Traceroute, another widely used network troubleshooting tool, relies on this protocol to trace the path data takes through a network.

  • Time Exceeded and Destination Unreachable

It also notifies when something goes wrong. Time Exceeded messages help identify network loops or routing errors, while Destination Unreachable messages indicate that the intended destination cannot be reached. These error messages are invaluable for network administrators trying to pinpoint and resolve issues quickly.

ICMP in Action: Real-World Applications

  • Network Monitoring

ICMP is the backbone of many network monitoring tools. By continuously sending and receiving echo requests and replies, administrators can assess the health and responsiveness of devices in real time.

  • Troubleshooting Connectivity

When network issues arise, Internet Control Message Protocol is often the first line of defence. Ping and traceroute commands assist in identifying whether a device is reachable and help isolate the location of any potential problems.

  • Security Considerations

While ICMP is a valuable tool for network management, it’s essential to consider security implications. Some security best practices involve limiting or controlling ICMP traffic to prevent potential abuse, as certain types of ICMP messages can be exploited for malicious purposes.

Conclusion: The Unseen Guardian

In the complex networking world, ICMP operates quietly, ensuring the smooth flow of information between devices. From basic connectivity checks to advanced network diagnostics, it plays a vital role in maintaining the integrity and efficiency of our interconnected world. As you delve deeper into networking, understanding this protocol and its specifics will undoubtedly empower you to navigate the complexities of the digital landscape.

What is TCP and Why Should You Care?

When connecting two computers to exchange data, TCP (Transmission Control Protocol) is the go-to protocol for reliable and secure communication. In this blog post, we’ll be exploring exactly what TCP is, how it works, its advantages and disadvantages, and its role in DNS. Keep reading to find out more!

Explanation of TCP

TCP (Transmission Control Protocol) is an end-to-end transport layer protocol used to establish connections and exchange data reliably between two computers over a network. It is an integral part of the Internet Protocol Suite and provides a connection-oriented service between two hosts. Using the reliable and efficient TCP protocol, network applications can send data reliably over the network without complicated protocols such as FTP. With its reliable and efficient data transmission, Transmission Control Protocol is ideal for applications such as web browsing and data transfer services.

How does it function?

TCP uses a set of rules known as a transmission control protocol. This protocol establishes a reliable, connection-oriented link between two computers and transfers data in a series of bytes. This is achieved by breaking the data into small chunks and adding a sequence number to each data part. Then, the receiving computer reassembles the data in the same order it was sent. Additionally, Transmission Control Protocol also has features such as error checking, retransmission of lost packets, and flow control to ensure the reliability of the data transfer. By following this protocol, TCP can reliably send and receive data between two points, creating a foundation for all the information we communicate on the internet today.

Advantages and disadvantages of TCP

One of the main advantages of the TCP protocol is its reliability. Following the designated rules and sequence of the transmission control protocol, TCP ensures that data is reliably sent and received in the same order. As a result, network applications can be confident that the data they are sending or receiving is accurate and complete. Additionally, TCP’s built-in error correction and flow-control features guarantee that connection-oriented issues, such as resending lost packets and controlling the data flow, are taken care of automatically.

Despite its advantages, TCP also comes with some disadvantages. One of the most significant drawbacks of the protocol is that it can be slow, especially compared to other connectionless protocols such as UDP. Additionally, Transmission Control Protocol requires an extensive amount of additional overhead information, resulting in more network traffic. This can lead to slower speeds and higher latency on networks with limited bandwidth. Finally, TCP is connection-oriented, meaning it cannot function properly on connectionless networks such as mobile networks. For these reasons, other protocols, such as UDP, are sometimes used instead.

The role of TCP in DNS

TCP plays an essential role in DNS (Domain Name System). It is explicitly used for resolving domain names, which means it sends the queries to the correct server and receives the response. To accomplish this task, Transmission Control Protocol uses a three-way handshake to establish the connection, followed by an exchange of requests, and then the client receives the response. After the response is received, the relationship must be closed. This is known as “graceful shutdown” and is handled by TCP. In this way, it provides an essential service to DNS, ensuring that data transmission is reliable and secure.

TCP monitoring – Everything you need to know


TCP is an essential part of the Internet Protocol Suite and is reliably used to send and receive data between two points. It provides an invaluable service to network applications with built-in error checking, retransmission capabilities, flow control, and gracefully closing connections. If you’re curious about how TCP works and why you should care, start by understanding its features, applications, and security implications.

Ping monitoring – Ensure uptime for your website

Being sure that your website is available on the Internet is an essential task you shouldn’t neglect. To check it 24/7 sounds complicated for a human, but not for Ping monitoring. Let’s find out more about it!

What is a Ping?

Ping or Packet Inter-Network Groper is a basic software utility often used by administrators of computing networks to test if a computer is reachable on an IP network. A ping is a tool that works on pretty much all operating systems (OS) with networking capability.

Shortly explained, Ping sends an echo request message to the IP of the computer that is being checked. It uses the ICMP or Internet Control Message Protocol. Then, it waits for an echo reply.

Check out an amazing Ping Monitoring service!

What does Ping monitoring mean?

Ping monitoring means a method of tracking network computer systems or domain names through the use of the Ping utility. In practical terms, Ping monitoring means an automated option to check if a network device (IP) or domain address responds, the quality of the connection, and the overall health of a system.

Downtime is a big concern for website owners because, during this time, their business is unavailable for users. As a result, the sales and business image are at risk! In this sense, Ping monitoring also means an effective and automated way to detect if your website stops responding or is inaccessible due to an outage. It detects the issue and alerts you to take fast action.

How does Ping monitoring work?

Ping monitoring works by sending automated ICMP echo requests to the destination you want to check. Then, it waits for echo replies, and based on them, it informs you about incidents or just continues monitoring.

You only have to point out the device or website (IP) to be checked and decide the frequency for the checking.

There are many types of websites. For some, operating with 100% uptime is essential. The big advantage of automated monitoring is that it can work constantly. Choose what is best for your business. Some administrators program these checkings every 30 seconds, others every 10 or more minutes.

Getting a reply, without packet loss, for the requests Ping monitoring sends is the best health signal you can get. It means everything is fine, so the monitor can keep working. However, if there is packet loss, the monitor will report this data. That is very useful for diagnosing or improving.

Now you know the device (computer, laptop, smartphone, etc) or website is online. Additionally, the monitor will test the strength or quality of the connection. It does this based on the response time that the Ping took.

If the Ping doesn’t get a reply, the monitor will begin a downtime incident. So it will alert the people you previously defined as responsible in such situations.
