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[…]

How Does IP Address Affect Site Performance and Security
It is a common misunderstanding that a shared IP address is not ideal for site performance and security. This is because most uninformed people mistake a shared IP address with a shared server. In a shared server scenario, the resources and computing power of a single server is shared by multiple websites, which can sometimes lead to privacy concerns. A shared IP address, on the other hand, means that the domain is mapped to an IP address that is shared between multiple domains. Both dedicated addresses as well as shared IP addresses can be suitable for hosting a website. In fact, the server on which the site is hosted will have more effect on its functionality and performance. Most web[…]

What is IP Addressing and How Does it Work?
IP addressing refers to assigning a 32-bit binary numerical label to all the devices connected to a network that communicates to the internet. The 32-bit IPv4 address is subdivided into 4 x 8-bit segments, which are known as octets. As only a few users work with 32-bit IPv4 addresses, the IP address is generally expressed in the dotted-decimal format. Here, each octet is assigned to an equivalent decimal number and the four decimal values are separated using periods. Typically, the eight binary bits can represent any number from 0 to 255. This means that each of the parts of the dotted-decimal in an IPv4 address can be any decimal from 0 to 255. Although IP addresses are broken into four[…]

Is a Dedicated IP Address Mandatory to Install an SSL Certificate?
An SSL certificate works by encrypting the data sent and received from/by a user’s device to/from a website. This gives users a secure channel to enter the necessary information on the browser and communicate with the webserver. Having an SSL certificate is also seen to help the website ranking and lead to better visibility on search engine result pages. Earlier, installing an SSL certificate was possible only on dedicated IP addresses. Yet as the importance of a secure internet grew, developments in technology created a way for shared IP addresses to use SSL certificates as well. This is possible through the Server Name Indicator or SNI, which allows a webserver to create different virtual host environments and host multiple SSL[…]

Everything you Need to Know about Shared IPv4 Addresses
A shared IPv4 address refers to an IP address that is used for multiple websites. Such types of IP addresses are generally used by shared hosting providers or for managed server hosting that uses a cloud-based platform. Choosing a shared IP address instead of a dedicated IP address also helps to cut the costs of server hosting, although there may be some risks associated with it. Shared IPv4 addresses and shared hosting normally go together. However, having a shared IP address does not necessarily mean that it is shared hosting. Regardless, as the IP address is used by multiple websites in shared hosting, the actions of one website may affect the reputation of the other sites on the server as[…]

What is a Private IP Address? – Infographic
As the name implies, a private internet protocol address identifies devices on a private or closed network. The word private refers to the fact that only those devices on the network can use this IP address to communicate with each other. A classic example of it is the IP address of your residential wireless connection. An address can either be static or dynamic. A state IP address is like your telephone number in that it stays the same unless you decide to change it. Conversely, a dynamic IP address changes occasionally, and it is most often utilized on business premises or in residences. Like any other form of IP address, the private one also has its own pros and cons.[…]
