About this course
This course develops practical capability in Subnetting. Its course-specific content covers Binary addressing, Subnet calculation, VLSM design, Plan validation, followed by an applied project focused on produce and verify an ipv4 address-allocation plan. The lessons include concrete configuration, design, testing or operational decisions appropriate to the subject.
Who this is for
Administrators, developers and practitioners who work with Subnetting or plan to take on responsibilities in this area.
Before you start
Basic computer literacy and a foundational understanding of networking. Prior experience with the named product helps with the practical exercises.
Produce and verify an IPv4 address-allocation plan
Deliver produce and verify an ipv4 address-allocation plan. Use the module outcomes to state requirements, demonstrate a working result, test an expected failure or boundary case, and document assumptions and follow-up work.
Course content
Course-specific syllabus and practical exercises. Lab release, access arrangements and final delivery scope are confirmed before enrolment.
01Binary addressing
+
- Network and host bits
- CIDR prefixes and subnet masks
Practical exerciseApply binary addressing to the produce and verify an ipv4 address-allocation plan and capture the validation evidence.
02Subnet calculation
+
- Network, broadcast and usable ranges
- Address-count and boundary checks
Practical exerciseApply subnet calculation to the produce and verify an ipv4 address-allocation plan and capture the validation evidence.
03VLSM design
+
- Allocate differently sized networks
- Summarisation and address-space conservation
Practical exerciseApply vlsm design to the produce and verify an ipv4 address-allocation plan and capture the validation evidence.
04Plan validation
+
- Check overlap, routing and growth assumptions
- Explain IPv6 prefix-planning differences
Practical exerciseApply plan validation to the produce and verify an ipv4 address-allocation plan and capture the validation evidence.
05Applied project: Produce and verify an IPv4 address-allocation plan
+
- Define inputs, assumptions and acceptance criteria for: Produce and verify an IPv4 address-allocation plan.
