UDP has truly earned its place as an integral part of the networking community. It’s a reliable and lightweight protocol enables fast communication between computers. And making it ideal for real-time applications like video streaming or online gaming. Moreover, with its many benefits over TCP, UDP will remain a key player in data transmission for years to come! So buckle up – let’s deeply dive into why UDP should be a crucial part of your networking toolkit!
How to stop a DDoS attack?
A DDoS is a very disruptive attack. Every online organization and business can suffer. Criminals don’t stop targeting victims. Therefore we can’t let our guard down! We have to be ready to stop them!
DDoS attack definition
A Distributed Denial of Service (DDoS) attack is defined as a criminal attempt to affect the regular operation of a targeted network, service, application, or server by saturating it with huge loads of malicious traffic. Different techniques are used by criminals to create, amplify, and send the traffic loads that are needed to shut down a target. What makes these attacks very effective is that traffic comes not from one but from many different sources. Multiple compromised devices around the world can take part in a DDoS attack. This makes a DDoS attack hard to stop and the attacker difficult to track.
Getting familiar with Private DNS server
Today we will explore one really important component of your secure online surfing – A Private DNS server. Let’s start.
Private DNS server: Explanation & Example
Let’s imagine you begin your Android/ Apple device’s search for various items while connected to a public network (like one at a shopping mall). Your search queries could be intercepted by someone else on the same network who has the necessary abilities, allowing them to know exactly what you’re looking for. That might not be hazardous, or it might be dangerous. In either case, why run the risk?
Ping command – Why do you need to use it?
Ping command – Definition
The Ping command is one of your operating system’s built-in network diagnostic commands (Windows, Linux, macOS, FreeBSD, etc.). Ping is used to testing connectivity between your device and the target, which can be a hostname such as google.com or an IP address such as 192.168.2.1.
Ping sends four 32-byte messages to the target by default, using the ICMP protocol (Internet control message protocol).
Popular examples of Ping command
Traceroute command: Definition & Examples
Do you need to know what path the queries take to your domain? Then, here comes the Traceroute command. Let’s see how this software can trace the route of queries and why this information is so useful.
Traceroute command – Definition
Traceroute command is software with CLI (command-line interface) that you can find inside most of the popular operating systems (Windows, macOS, Linux, BSD, and more) and serves to check the route from your device to a destination (domain name or IP address).
The Traceroute traces the route to the target by sending queries, waiting to get the results, and showing you statistics about the package delivery. You will know what time the packages take to get to the end destination and if there were lost packages.
List of most common DNS records
The Domain Name System (DNS) is essential for the Internet to work. Network administrators deal daily with DNS records. But DNS and its records can be hard to digest for new people in this business.
If you want to understand the functionality of the most common DNS records, here you have!
A or AAAA records
These two DNS records are in charge of linking a domain name with its corresponding IP address.
Both records have the same purpose. The difference is that A works with Internet Protocol version 4 (IPv4), while AAAA works with Internet Protocol version 6 (IPv6).
Monitoring service: Should you invest in it?
What does a Monitoring service aim to achieve?
Monitoring service is a simple, secure, real-time web-based service that acts as a second set of eyes on the health and status of your organization’s physical infrastructure. It monitors resources using metrics, and alarms notify you when these metrics meet alarm-specified triggers.
Monitoring services aid in the detection of problems with your services such as web, DNS, email, and so on. As a result, it is a must-have if you want to provide dependable service and an excellent user experience. This service offers detailed information about the condition of your servers. Furthermore, by monitoring your servers in real-time, you can detect and resolve any issues in a short period of time.

What do you need to know about TTL?
Time-to-live (TTL) is the value that specifies the time period or number of hops that a data packet must travel to be alive. Either across the network or in the memory cache. It will be terminated when this timer expires, or the data packet reaches its hop limit. Data packets are not all the same; they vary in size and shape, but each has a different TTL. The amount of time data packets should live in a device to perform their missions should be determined.
