Pros & Cons of Proxy Server – Infographic
The term ‘proxy server’ refers to a remote system that connects an internet user to the server that hosts the website they are trying to access. The server can hide one’s Internet Protocol address with its IP address so that the site will only see the latter address. That means it can mask the user’s online activity and make it seem like they are surfing the internet from a place different from their actual location. So, proxy servers allow accessing geographically restricted content. This infographic covers all of the benefits and disadvantages of using this server for internet users.

Smart Ways to Protect Your IP Address from Hackers
An IPv6 or IPv4 address is like the identity of your device in the world of internet. All of the data and traffic transmitted and received over the network to and from your computers and devices are maintained with the help of an IPv6 or IPv4 address. This means that if hackers gain access to your IP address, they can exploit it for various malicious purposes. Worry not – there are many ways to protect your IP address from cybercriminals. Below are a few smart tips to thwart hackers from accessing your IP address. Set Up Unique Passwords Creating strong device and network passwords can easily restrict people from accessing your computers and business or personal networks. Cybercriminals can easily[…]

Types of AWS IP Address – Infographic
AWS services come with three forms of Internet Protocol addresses, as shown in this infographic. A public Internet Protocol address comes from a form of subnetwork that can be publicly routed over the internet. A private IP address is useable to communicate from one instance to the other in the Virtual Private Cloud. For your information, an instance here means a virtual web server. An elastic Internet Protocol address is made to facilitate dynamic cloud computing. It is possible to associate Amazon’s virtual server with any one of these three address types. Find more information about these here.

Everything You Need to Know About IP Spoofing
Spoofing refers to a particular type of cyberattack, where hackers exploit a device or network to trick other networks by making it seem like a legitimate action. IP spoofing allows cybercriminals to gain access to user computers to mine sensitive personal information and business data, take over the device for malicious use, or run Denial-of-Service (DoS) attacks. What is IP Spoofing? IP spoofing works by exploiting the data packets sent and received over a network. Hackers use different tools to modify the source IP address in the data packet, which makes the destination IP address see it as a trusted source and accept the transmission. As all of that happens at the network level and there are no signs of[…]

Understanding the Differences between TCP/IP and OSI Models
TCP and IP are the two main network protocols or communications standards of the internet. Where TCP defines how different applications can communicate over reliable channels across a network, IP regulates how devices connected to the internet can transmit and receive data over the network or an interconnected set of networks. In other words, IP defines routing and addressing while TCP defines how the connected peripherals can communicate across the IP-mediated link without any data loss. The OSI or Open Systems Interconnection model, on the contrary, defines how the different tasks related to the network communication can be segregated across multiple layers of software and hardware components. It was developed by the International Organization for Standardization (ISO) as the ISO/IEC[…]

Everything You Need to Know About a Subnet Mask
A subnet, or sub-network, refers to a network within a network, which is assigned to make the parent network more efficient. Administrators use subnets to facilitate effective network traffic over a shorter distance without requiring the signals to pass through multiple routers to reach the destination. A subnet mask is a 32-bit number like an IPv4 address but it masks the IP address for internal purposes and divides the IPv4 address into network address and host address. For instance, network routers employ subnet masks to route data packets to the specified destinations. In general, a subnet mask comprises of network bits that are set to 1s and host bits that are set to 0s. In any network, there are two[…]

Understanding the Differences between TCP and IP
TCP (Transmission Control Protocol) forms a core standard of the Internet Protocol Suite that governs the communications across the internet and other computer networks. It operates at a much higher level when compared to IP (Internet Protocol), which is another principal communications standard. The major concerns of TCP remain the two ends that send and receive data packets, such as a web server and the browser on a user’s computer. TCP ensures optimal delivery of data packets to and from both ends to establish and maintain the connection. Apart from that, TCP also manages flow control, size of the data packets, the data exchange rate, as well as congestions in the network traffic. IP, on the other hand, maintains data[…]

What is Transmission Control Protocol (TCP)?
Transmission Control Protocol or TCP is a network standard that refers to how a network conversation can be established and maintained so that the connected applications and programs can share data. TCP and IP (Internet Protocol) work together to define how computers can send packets of data, forming the basic rules of data transfer over the internet. How Does Transmission Control Protocol (TCP) Work? TCP works based on a connection-oriented system, meaning that it establishes and maintains the connection until the applications have completed exchanging data at both ends. The TCP layer determines how the data is broken into packets to facilitate its transfer over the network, as well as sends and accepts data packets to and from the network[…]

What Does IPv4 to IPv6 Tunneling Mean?
IPv4 to IPv6 tunneling refers to using the existing routing infrastructure of your IPv4 address to carry the imminent IPv6 traffic. This helps to successfully transition to IPv6 by ensuring compatibility with the IPv4 hosts and routers installed at present. Besides, maintaining compatibility between the infrastructure systems also allows you to streamline the process of transitioning to IPv6. That is because you can still use the IPv4 routing infrastructure while deploying IPv6 to make the most of the available resources. IPv4 or IPv6 routers and hosts can tunnel IPv6 datagrams over IPv4 address routing topology by including them within the available IPv4 packets. In general, IPv4 to IPv6 tunneling can be done in the below ways. Router-to-Router: Here, the IPv4[…]

Everything You Need to Know about CIDR
CIDR or Classless Inter-Domain Routing stands for an IP addressing method that is designed to improve the efficiency of IP address allocation. CIDR replaces the previous system of distributing IP addresses based on Class A, Class B, and Class C networks. The new method is also seen to benefit IPv4 addresses and extend their life cycles while slowing the development of routing tables. Also known as supernetting, the main goal of CIDR was to decelerate the rapid exhaustion of IPv4 addresses across the internet. This eventually led to freeing up a lot of unused and available IP addresses. At the same time, it also helped to deal with many of the inefficiencies of the old method of IP addressing that[…]
