VLAN / Subnet Planner
Sites, VLANs, floors and rooms in; an aligned VLSM plan out — plus the IP addressing-standard document to hand to a client or the next tech.
- ✓Multi-site with overlap checks
- ✓Brownfield: plans around subnets already in use
- ✓CCNA study mode that shows the work
- ✓Markdown and Word export
Incident Postmortem
Paste messy incident notes or a chat log; get a blameless postmortem with a clean timeline, time-to-detect / mitigate / resolve, and owned action items.
- ✓Timeline parsed from pasted notes
- ✓Blameless-ness lint before you publish
- ✓Action items typed prevent / detect / mitigate / process
- ✓Markdown and Word export
Planned — in build order
Onboarding / Offboarding Builder
Per-role checklists with the accounts, groups, devices and access each role needs — and the reverse on exit.
Network Topology Document
A written network description generated from a device and link inventory, with a diagram-as-code export.
Change Document
Change request, implementation plan, test plan and rollback, from one short form.
Firewall Rule Change-Log
A rule register that records who asked, why, when it was added, and when it should be reviewed.
Why documents, not calculators
Free subnet calculators are everywhere. What nobody hands you is the addressing standard, the postmortem, the change record — the artefact that outlives the engineer who knew the network by heart.
One suite, one data model
The addressing plan from module 1 becomes the input for the topology and change modules. The moat is the suite, not the math.
Built by a member of the audience
Written by a Tier 1/2 tech with seven years of support and network work, studying for the CCNA — which is why the planner shows its working.
