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.

Supported Triggers and Actions
Notis builds workflows that link Linear to Big data cloud. A trigger fires from one place; an action lands in another.
Linear triggers
Big data cloud actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Am I Roaming API
Tool to determine if the user is roaming based on their ip address and gps coordinates. use after obtaining device location to verify roaming status before mobile actions.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
ASN Extended Receiving From Info API
Tool to return upstream providers (receivingfrom) for a given asn. use when you need a paginated list of ases feeding traffic for the specified asn.
Comment Received Trigger
Triggered when a comment is received.
ASN Extended Transit To Info API
Tool to return downstream customers (transitto) for a given asn. use when you need a paginated list of ases receiving traffic from a specific asn.
Issue Created Trigger
Triggered when a new issue is created.
ASN Rank List API
Tool to fetch a ranked list of autonomous systems by ipv4 announcement volumes. use after you need to compare or analyze as ranks.
Issue Updated Trigger
Triggered when an issue is updated. For example labels are changed, issue status is changed, etc.
BGP Active Prefixes API
Tool to retrieve ipv4 or ipv6 prefixes currently announced on bgp. use when inspecting bgp routing announcements for a given asn.
Private Team Comment Created
Fires when a new comment is posted on an issue in a private Linear team (polled with the connected user's token).
Reverse Geocoding With Timezone API
Tool to return reverse geocoding and time zone info for given coordinates. use when you need both locality details and timezone data in one call.
Private Team Issue Created
Fires when a new issue appears in a private Linear team (polled with the connected user's token).
Country by IP Address API
Tool to geolocate an ip address and retrieve country details and demographics. use when you need country-level data after obtaining the target ip address.
Private Team Issue Properties Updated
Fires when properties on an issue change in a private Linear team (polled with the connected user's token).
Country Info API
Tool to fetch detailed country information by iso code. use when you need localized names, currencies, regions, and other metadata for a country.
