If you want to connect a computer, smartphone, etc. to a network (LAN or Wifi), you can either assign the IP address manually, or get it automatically. The latter is possible thanks to the DHCP (dynamic host configuration protocol) communication protocol, which has established itself as the cross-platform standard solution for address management. The forerunner was the BOOTP bootstrap protocol...
For many years, dedicated IPs were an important component within hosting and mailing. To this day, you can choose a dedicated IP address for your project from a wide variety of services. But is a dedicated IP really a better solution than a shared address? We’ll show you what you need to know about the two IP types and dispel common myths.
An IP address is assigned to all devices in a computer network. This makes them uniquely addressable and identifiable. Data packets are transported from the sender to the recipient using the IP address. Thanks to this address, routers can send the data packet to the correct recipient. So, how do you find your IP address?
Without TCP/IP protocols, you wouldn’t be able to read the words on this page. TCP and IP, the two foundational protocols of the suite, along with other related sets of rules, define how computers communicate over the Internet and other networks. In fact, the standards are so established that every device on the Internet follows these protocols to ensure the smooth transfer of data.
Some cookies can be very helpful – they let you sleep on those impulse purchases and keep them from disappearing out of your shopping cart, or log into social media sites with just one click. But not all cookies make surfing the web easier, and some may even forward unwanted information to third parties. It is a good idea to learn how to clear cookies, and this guide will show you how to clear...
Quick UDP Internet Connections (QUIC for short), is an experimental network protocol from Google. Further development of the protocol is being driven by IETF, which has set up a dedicated group working towards it. The QUIC protocol is intended to offer a speed-optimized alternative to the current transport standard TCP and builds on the connectionless protocol UDP to achieve this.
For computer systems to be able to communicate with each other and exchange information, they need common ground, just like humans must share a common language. But computers don’t rely on foreign language lessons, and instead only need the appropriate network protocol to successfully communicate. This provides guidelines and structures for the data transfer, and so plays a decisive role in the...
The Internet protocol family – the cornerstone for communication on the Internet – has around 500 members who work on a wide variety of layers. For example, the connectionless User Datagram Protocol (UDP) is responsible on the transport layer for the transmission of packets that were previously addressed via the Internet Protocol (IP). In this guide, you can find out exactly what distinguishes...
The NTLM protocol was a practical solution for Windows devices for a long time: A user just had to sign in once and then gain direct access to various network services. However, this authentication method is now considered unsafe and is no longer in use. How does NTLM work, and why do users now prefer to use Kerberos?
As a global computer network, the Internet provides the perfect foundation for gathering and distributing information. The World Wide Web, the most well-known Internet service, convincingly proves this fact. The older Usenet benefits from the Internet’s global network as well. In order to be able to transfer data, it relies on the unique NNTP, which is the focus of this article.
