Network CIDR Range Analysis

Define a security boundary and instantly see every network inside it. CIDR analysis runs automatically.

Trigger

Issue Created Trigger

Triggered when a new issue is created.

Action

Networks by CIDR

Tool to retrieve bgp-announced networks within a specified cidr range. use when you need to analyze network announcements within a particular cidr after confirming the range format.

Why this helps

Security scoping requires manual CIDR analysis. Details get lost in spreadsheets instead of staying in your security planning.

  • See all networks within your CIDR block without manual calculation
  • Instantly validate security scope coverage
  • Keep network boundaries documented in Linear
  • Reduce calculation errors in security planning

Setup

Build it in a few focused steps.

  • 1Connect your Linear workspace and Big Data Cloud CIDR analysis APIs to Notis.
  • 2Create an automation: 'When a security perimeter issue is created with a CIDR notation, retrieve all networks announced within that range.'
  • 3Select 'Issue Created' as your trigger.
  • 4Route analysis results to your #security channel or keep them in Linear.
  • 5Test by creating a security issue with a known CIDR (e.g., 10.0.0.0/8) and verify Notis lists all networks in that range.

Questions about this workflow

What's CIDR notation?

CIDR (Classless Inter-Domain Routing) is shorthand for IP ranges. 10.0.0.0/8 means all IPs from 10.0.0.0 to 10.255.255.255. Notis uses this notation to find all networks inside.

How many networks can be in a CIDR?

Depends on the size. A /24 has 256 IPs. A /8 has millions. Notis handles any valid CIDR notation.

Does this help with firewall rules?

Yes. It shows you what you're actually allowing through your firewall boundary. Compare against what should be there.
