Essential IP addressing and subnetting

A 2 day
training course

IP addressing and subnetting course description

A course focusing purely on IP addressing and subnetting. The course assumes that delegates already have some knowledge of IP addressing. In particular delegates will be able to calculate subnet numbers in seconds without using binary.

Key outcomes from this course

By the end of the course delegates will be able to:
  • Calculate subnet numbers in seconds
  • Design IP addressing schemes.
  • Troubleshoot IP address problems.
  • Calculate CIDR prefixes in seconds

Hands on: IP addressing plans

Allocations and assignments

Hands on: Querying the RIPE database.

Private addressing and NAT

Why Choose Us

SNT trainers score an average of over 90% on the three main areas of:
  • Ability to teach
  • Technical knowledge
  • Answering questions
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM

We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
