📜 Playbook — IP Range / CIDR exploitation
- Direction — frame the requirement for IP Range / CIDR: what decision does this support, by when?
- Collection — pull the 0 mapped sources (0 free) and the native workbench (open); capture provenance and observe OPSEC.
- Processing — normalize, de-duplicate and enrich the collected data.
- Analysis — correlate against local holdings; apply ACH; assign confidence.
- Dissemination — open a case, draft a report, share via STIX/MISP.
- Feedback — set an alert rule / watchlist to monitor for change.

🎫 IP Range / CIDR
A CIDR block is an IP range expressed as a prefix and mask (e.g. 192.0.2.0/24) representing a contiguous allocation of addresses. In investigations it defines the ownership and scope of infrastructure, enables range-based blocking and hunting, and links individual hosts to their allocating organization and routing ASN.
Format: network/prefix-length: IPv4 /0-/32, IPv6 /0-/128; network address must align to the mask boundary (host bits zero for canonical form).
