DHCP: An overview of the Client/Server protocol
DHCP: What’s behind the Dynamic Host Configuration Protocol
  • Configuration

If you’re connected to an internet router and power on your computer, it automatically obtains the necessary network parameters, such as the IP address, subnet mask, or DNS server. This is made possible by the Dynamic Host Configuration Protocol (DHCP), which simplifies address assignment when connecting to the internet and makes setting up local networks easy as pie.

MPLS:  What is Multiprotocol label switching?
MPLS: What’s behind the network technology
  • Know-how

Speed and reliability play an important role for data transfer in networks. They reflect the quality of the connection, which is why providers do everything they can to guarantee the agreed services. A method primarily used in virtual private networks is the so-called multiprotocol label switching (MPLS).

What is Neighborhood Discovery Protocol(NDP)?
Neighbor Discovery Protocol (NDP) – what is it?
  • Know-how

Network configurations today are done quickly. For those who do not rely on their own fixed settings for routers, computers, and more, the Internet Protocol family provides the appropriate set of automatic mechanisms to determine critical parameters, such as the default gateway, IP address, and MAC address.

Penetration testing – the complete network check
Penetration test: how to find weak points in your network
  • Know-how

The more complex a network is, the more vulnerable it is to attacks. In times when customers and partners have access to internal network structures via the internet, and can control various applications via web interfaces, IT employees are encountering more and more problems. Large companies, in particular, prefer to use penetration testing to check how well their security concept works. This...

NAT: How Network Address Translation works
NAT: Network Address Translation in the router
  • Know-how

NAT, the network address translation, is closely tied to the internet standard IPv4 and will disappear from the internet along with it. But the implementation of IPv6 is slow to take over, and many internet users worldwide still surf with the fourth version of the internet protocol. As a result, network address translation via NAT tables remains current. In our guide, we answer the questions: What...

Port scanning: introduction and basics
How port scanning contributes to your system’s security
  • Know-how

It’s easy to lose track of all the different programs that are responsible for inbound and outbound data traffic. Networks hosting a large number of computer systems that are constantly communicating with online services often require technical backup. High-performance tools check the activities of various applications or computers and can close existing security gaps. Using port scanners is one...

Protection against ransomware, spyware, and scareware
Ransomware, adware, etc. – how can you protect yourself?
  • Security

The internet is a playground for cybercriminals and fraudsters – for many, this is an annoying and frightening reality. The threats from unwanted software range from harmless advertising to trojans, which can paralyze complete computer networks. The forms of malicious software or malware are diverse, the countermeasures often very simple. In our article, you can read about how ransomware, spyware,...

Bonjour: Software for zero configuration networking
Bonjour: What’s behind the zeroconf implementation
  • Know-how

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...

Subnetting: How do subnets work?
Use subnetting to get the most out of your network
  • Know-how

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...

Honeypots: IT security through decoy programs
What is a honeypot?
  • Security

Businesses use IDSs (intrusion detection systems) and firewalls in order to keep attackers away from sensitive IT systems. These safeguards can be enhanced through so-called honeypots, which bait hackers to isolated network areas where more information on their attack patterns can be collected. Find out more here on how honeypots work and with which programs honeypots can be implemented for both...

Server

IONOS Server Guide: professional tips on configuration and administration

Servers are what make up the physical basis of the internet. Setting up your own professional site, putting products online for sale, or connecting multiple company locations with one another: all of these tasks require the support of high-performance computers. And it doesn’t matter if you purchase hardware resources for your own data center or opt for the flexibility of cloud services: operating a server comes with the challenge of independently configuring and administering hardware components. But don’t worry, there’s a lot of support out there for these tasks. In the Server Guide of IONOS’s Digital Guide series, you’ll find regular articles, news, and tutorials on how to operate this indispensable component of today’s IT infrastructure.

 

Server information for businesses, developers, and tech hobbyists

Packed with practical tips, our guide covers a wide spectrum of topics primarily aimed at mid-sized companies, freelance developers, and tech hobbyists. While some articles, like ‘What is a server?’ or ‘DNS – name resolution online’ cater more to beginners, experts are by no means left hanging; there’s a wide range of detailed texts and tutorials on important tasks like choosing the best operating system, filling security gaps, or getting the best possible performance out of your software and hardware.

 

What you can expect in the IONOS Server Guide

If you take a look, you’ll notice our guide is divided into four different subcategories, each covering a different topic. The ‘KnowHow’ area sets out to familiarize beginners with the basics of operating a server. Details on different server types and how to use them are also laid out here. Tips and tricks on managing server software is found under the keyword, ‘Configuration’. The category, ‘Security’ is all about dealing with potential problems server operators may encounter from online threats. Conventional methods of attack, like viruses, worms, and Trojans, and what you can do to combat them are explained here. And the category, ‘Tools’, provides useful guidance on what resources can help make administering your server a more manageable task.
