ASN Information | Autonomous System Intelligence

image.png

The platform available at https://dash.niamonx.io/asnchecked — known as ASN Information — is an autonomous system intelligence tool within the NiamonX platform. It allows users to check detailed public information about an Autonomous System Number, including organization profile, country, routing scope, traffic category, IPv4 and IPv6 prefix counts, contact information, abuse contacts, RIR status, owner address, policies, website, and raw ASN metadata.

Overview of the Service

ASN Information is designed to help analysts, network engineers, SOC teams, infrastructure owners, cybersecurity researchers, and OSINT specialists quickly understand the public profile of an Autonomous System.

An Autonomous System, or AS, is a network or group of networks operated under a single routing policy on the Internet. Each AS is identified by an ASN, such as:

AS13335

or:

47215

The tool accepts ASN values with or without the AS prefix and returns a structured report containing routing, ownership, policy, contact, traffic, and organization information.

ASN Information is useful for network attribution, abuse reporting, infrastructure mapping, threat intelligence enrichment, routing analysis, vendor review, hosting-provider identification, and incident response.

🔍 How the Tool Works

When a user enters an ASN, the tool queries public and internal intelligence sources and returns the available ASN profile.

The result may include:

  • ASN number

  • Organization name

  • Country code

  • Traffic ratio

  • Traffic volume category

  • Network type

  • IPv4 prefix count

  • IPv6 prefix count

  • Routing scope

  • RIR status

  • Last updated date

  • Abuse contacts

  • General email contacts

  • Website

  • Owner address

  • Peering policy

  • IRR AS-SET

  • Route server information

  • Looking glass information

  • Social media or website links

  • Associated prefixes

  • Raw JSON

Data may be aggregated from public routing, RIR, IANA, peering, WHOIS, and organization sources. Because ASN data can come from multiple public datasets, it should be treated as intelligence context and validated before critical decisions.

🧩 What Can Be Checked

ASN Information accepts Autonomous System Numbers.

Supported input examples:

AS47215

47215

The AS prefix is optional.

Unsupported input examples:

example.com

1.1.1.1

https://example.com

AS47215/example

For IP addresses, domains, ports, or service-level intelligence, users should use the relevant NiamonX IP or DNS modules.

⚙️ Interface Structure

The ASN Information interface contains several main areas.

ASN Input

The user enters an Autonomous System Number.

Example:

AS47215

The tool normalizes the value and performs the lookup.

Important: prefix lists can change over time. Always validate current route announcements with routing tools, RIR data, or BGP sources when making operational decisions.

📡 IPv4 and IPv6 Support Indicators

ASN Information may show whether IPv4 and IPv6 routing data is available.

Example fields:

info_prefixes4: 30
info_prefixes6: 5
info_ipv6: true

IPv4 Prefix Count

Shows how many IPv4 prefixes are associated with the ASN in the returned profile.

IPv6 Prefix Count

Shows how many IPv6 prefixes are associated with the ASN in the returned profile.

IPv6 Indicator

Shows whether the ASN has IPv6-related information or support in the returned dataset.

These fields are useful for understanding the network’s routing footprint and protocol support.

📈 Traffic Ratio

The traffic_ratio or info_ratio field describes the estimated direction of network traffic.

Example:

Mostly Outbound

Possible categories may include:

  • Mostly Outbound

  • Mostly Inbound

  • Balanced

  • Heavy Outbound

  • Heavy Inbound

  • Unknown

This value is an assessment and should be treated as a routing or peering profile indicator, not as a precise measurement.

Interpretation

A Mostly Outbound network may primarily send more traffic than it receives. This can be common for hosting providers, content providers, certain infrastructure operators, or networks serving outbound-heavy workloads.

A Mostly Inbound network may receive more traffic, which can be common for access networks, eyeball networks, or consumer ISPs.

🌍 Scope and Traffic Category

The tool may show routing scope and traffic volume category.

Example fields:

info_scope: Europe
info_traffic: 1-5Gbps

Scope

Indicates the likely geographic or operational scope of the network.

Examples:

  • Europe

  • North America

  • Global

  • Regional

  • Unknown

Traffic Category

Shows approximate traffic volume category.

Examples:

  • 100Mbps-1Gbps

  • 1-5Gbps

  • 5-10Gbps

  • 10-20Gbps

  • 20Gbps+

  • Unknown

These fields are estimates and should not be interpreted as guaranteed real-time bandwidth measurements.

🧾 Contacts

ASN Information may display contact counts and contact-related fields.

Important contact types:

Contact Type Description
Abuse contacts Email addresses for abuse reporting
Email contacts General public contact emails
Contact export Exportable contact information when available

Abuse Contacts

abuse_contacts are used to report abuse such as spam, phishing, malware, scanning, botnet traffic, or other malicious activity.

Example use cases:

  • Reporting malicious traffic

  • Submitting phishing complaints

  • Notifying a network operator about compromised systems

  • Escalating security incidents

  • Abuse desk routing

Email Contacts

email_contacts may include additional public email addresses for administrative or technical communication.

Contact data may be incomplete or missing depending on the source.

🏛️ IANA and RIR Data

The tool may include IANA and RIR-related fields.

Possible data includes:

  • RIR status

  • RIR status update date

  • IANA assignment status

  • WHOIS-related source fields

  • whois_server when available

RIR Status

The RIR status indicates whether the ASN profile appears valid or active in the returned registry data.

Example:

rir_status: ok
rir_status_updated: 2024-06-26 04:47:55

Regional Internet Registries include organizations such as RIPE NCC, ARIN, APNIC, LACNIC, and AFRINIC.

This data is important for attribution, validation, and abuse-reporting workflows.

🤝 Peering and Routing Policy

The ASN profile may include policy-related fields.

Possible fields:

Field Description
policy_general General peering policy
policy_locations Peering location requirements
policy_contracts Contract requirements
policy_ratio Whether traffic ratio is considered in policy
policy_url URL to public peering policy
irr_as_set IRR AS-SET for routing policy
route_server Route server participation
looking_glass Looking glass system, if available

Example:

policy_general: Open
policy_contracts: Not Required
irr_as_set: AS-FILOO

These fields are useful for peering research, network operations, IX participation analysis, and BGP routing review.

🔎 IRR AS-SET

An IRR AS-SET is a routing registry object that groups ASNs or routes for routing policy purposes.

Example:

AS-FILOO

IRR AS-SET values are useful for:

  • Route filtering

  • Peering configuration

  • BGP policy review

  • Network operations

  • Prefix validation

  • Transit and peering analysis

IRR data should be validated because registry objects can become outdated.

🔭 Looking Glass

A looking glass is a public network diagnostic tool offered by some network operators.

It may allow users to check:

  • BGP routes

  • Ping results

  • Traceroute results

  • Route server visibility

  • Peering paths

If a looking glass URL is available, the ASN Information tool may show it in the profile.

If it is not available, the field may show:

🧬 Raw JSON

The tool provides Raw JSON for advanced analysis.

Raw JSON may include:

  • ASN profile

  • Organization data

  • Prefix list

  • Contact data

  • Policy fields

  • Peering metadata

  • RIR status

  • Website and social links

  • Routing scope

  • Traffic category

  • Internal status fields

Raw JSON is useful for:

  • SOC workflows

  • API-style integrations

  • Case management

  • Evidence preservation

  • Automated enrichment

  • Network inventory systems

  • BGP research

  • Compliance reporting

Raw data should be handled carefully when used in investigations or internal reports.

🕓 ASN History

The tool stores ASN lookup history locally in the browser.

History entries may include:

  • ASN value

  • Organization name

  • Country

  • Lookup timestamp

  • Summary fields

Local history helps users repeat previous ASN checks and compare recent lookups.

Because it is stored locally, it may be cleared when the user clears browser data, switches devices, or uses a different browser profile.

On shared devices, users should clear local history if ASN investigations are sensitive.

  • Contact fields may be missing or outdated.

  • Prefix lists may change over time.

  • Traffic categories are estimates.

  • RIR status does not guarantee current operational behavior.

  • WHOIS and registry data may differ from real-world operations.

  • ASNs can be used by hosting providers, enterprises, ISPs, CDNs, or transit networks.

  • A malicious IP inside an ASN does not mean the ASN owner is malicious.

  • Abuse contacts may be absent even for active networks.

  • Always validate important findings with live BGP, WHOIS, RIR, and provider sources.

If a server-side 500 error occurs during lookup, repeat the request.
