Overview

“Networking Fundamentals TCP/IP” is designed for roles such as Network administrators and network engineers and System administrators with network responsibility. In 6 hours you work your way through OSI and TCP/IP models, IPv4 addressing and subnetting and Ethernet, ARP and MAC addresses in a structured way – with plenty of practice and time for your questions.

A stable, secure network is the prerequisite for almost every IT service, and with cloud connectivity, remote work, Wi-Fi and segmentation, complexity keeps growing. Our Networking Fundamentals TCP/IP courses are aimed at network administrators, system owners and security teams who need to design, configure and secure networks and get them running again quickly after incidents. We combine protocol understanding with practical configuration: you work in a provided lab with real or virtual devices and analyze traffic yourself. The course runs online or on site, lasts one day and is offered at a fixed price per participant.

The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.

Frequently asked questions

Who is the Networking Fundamentals TCP/IP course for?

It is for network and system administrators, security owners and architects who plan, operate or secure Networking Fundamentals TCP/IP. Beginners learn the concepts, while experienced engineers deepen design, troubleshooting and automation. In a short pre-call we clarify your priorities.

Do we work on real devices?

For Networking Fundamentals TCP/IP we use a lab with real or virtualized network devices and analysis tools. You configure on your own, provoke failures and evaluate traffic. Your company's production networks are not touched.

How much does “Networking Fundamentals TCP/IP” cost?

The course costs a flat €949 plus VAT per participant – whether online or on-site. This includes 6 hours of live training with a trainer, course materials, a lab environment and a certificate of attendance.

Can I suggest my own date?

Yes. For every location we suggest a date roughly four weeks ahead. In the request form you can always describe your preferred date or period in free text – we check availability and get back to you within one working day.

Is the course online or on-site?

Both are possible: live online in a virtual classroom or on-site in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run the course exclusively for your team.

Can the course be tailored to our team?

Yes. Tailor-made courses cost approx. €4,500 more, depending on the topic and by arrangement. We agree content, examples and exercises with you in advance.
