📜 Playbook — IP Range / CIDR exploitation

  1. Direction — frame the requirement for IP Range / CIDR: what decision does this support, by when?
  2. Collection — pull the 0 mapped sources (0 free) and the native workbench (open); capture provenance and observe OPSEC.
  3. Processing — normalize, de-duplicate and enrich the collected data.
  4. Analysis — correlate against local holdings; apply ACH; assign confidence.
  5. Dissemination — open a case, draft a report, share via STIX/MISP.
  6. 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).

📡 How it is collected

  • RIR allocation / assignment records
  • BGP announced prefixes
  • Whois netrange objects
  • IP-to-ASN mapping expansion
  • Reverse DNS delegation zones
  • Scanning coverage inventories

🧩 Analysis & hunting techniques

  • Range expansion and live-host sweeping
  • Netblock ownership / abuse-contact lookup
  • Reputation aggregation across the range
  • More-specific / less-specific prefix analysis
  • Reverse-DNS zone mapping
  • Allocation-history tracking
  • Range-wide service fingerprinting
  • Bulk blocklist generation
