Manually organizing a large local network can be a nerve-wracking and very complicated matter. Without your own DHCP and DNS servers to support you in the distribution of addresses and name resolution, all IPs would have to be entered manually and also updated independently if changes are made in the network. Zeroconf implementations like Bonjour, which connect network components without almost no...Bonjour: What’s behind the zeroconf implementation
Dividing a corporate network into smaller subnets has some advantages in terms of speed, security, and logical organization. However, many people find it difficult to set up. Binary computational operations and long series of numbers are frightening, but the principle itself is not so complicated. We explain what subnetting is, how to calculate a subnetmask, and what you need subnets for, so that...Use subnetting to get the most out of your network
IP addresses are essential for modern digital communication. They are the 'connection numbers' of all devices in the network and this is why they are one of key foundation elements of the internet as well as other networks. Communication is based on a common 'language': the internet protocol. But what exactly is a floating IP and what is it used for? What is the difference between a floating IP of...What is a floating IP?
IPv6 is the newest version of the internet protocols, and should overcome the central issues of its predecessors. Included in these issues is the impending shortage of IPv4 addresses as well as the violation of the end-to-end principle by the strict separation of public and private IPs. This article gives an overview of the functions of IPv6 as well as the structure and distribution of address...IPv6: All about the new internet standard
Raspberry Pi is the first choice for do-it-yourselfers around the world when it comes to single-board computers: It’s small, cheap, and meets most server and media center requirements. But more and more manufacturers are putting their own mini-computers on the market: Raspberry Pi alternatives want to set themselves apart with lower prices, more powerful hardware, or edgy and exceptional features....Four current Raspberry Pi alternatives: Single board computers by comparison
Operating systems have gone through some major changes over the years. While their beginnings are rooted in more humble, purely text-based user interfaces, today’s options have evolved into complex software packages with graphical interfaces, comprising an elegant go-between for hardware and software applications. Users, who have long since been equipped with a keyboard and mouse, are able to...Server operating systems: history and today’s situation
The equation is simple - without it, there’s simply no web content: when a web server is out of order, then it’s no longer possible to call up any websites that are connected to it. Web servers are what allow online presences to reach the internet in the first place. But just how do these systems work? Which functions do the programs responsible for this task offer? And what’s an example of a good...What is a web server? And which web server software is there?
A big problem with the previous Internet Protocol version, IPv4, was the missing guarantee of security standards of integrity, authenticity, and confidentiality. This previous protocol lacked the necessary means to identify data sources or enable secure transport. The protocol suite IPsec, developed for IPv4’s successor, IPv6, has changed the situation for Internet Protocol overnight.Secure network connections with IPsec
