Network documentation falls into distinct categories, each serving a different purpose during operations.
Diagrams show topology, both logical and physical. You use these for troubleshooting and planning.
IP address records track allocations, subnets, and VLANs. These prevent conflicts and simplify audits.
Configuration backups store device configs for restoration after failures.
Procedures document how to perform tasks. Runbooks, SOPs, and playbooks fall here.
Change records track what changed, when, and why.
