What Is an ASN? Why Your IP Address Type Matters for Business Verification
Every IP address belongs to a network with a classification. Platforms use that classification to judge whether your connection looks like a real business or a bot behind a proxy.
What Is an ASN? Why Your IP Address Type Matters for Business Verification
The Number Behind Your Connection
When you connect to Amazon, Stripe, or any platform from your computer, your IP address is visible. Most people know this. What most people do not know is that the IP address itself is less important than the network it belongs to — and that network has a public classification that tells platforms a surprising amount about who you are.
That classification starts with a number called an ASN.
What Is an ASN?
ASN stands for Autonomous System Number. In plain terms, it is the ID number assigned to the network operator that owns a range of IP addresses.
Every IP address on the internet belongs to an Autonomous System — a network operated by a single organization. Your home internet provider is an Autonomous System. Google Cloud is an Autonomous System. A mobile carrier is an Autonomous System.
The ASN tells you who operates the network. For example:
**AS7922** — Comcast (residential and business ISP)
**AS16509** — Amazon Web Services (cloud/datacenter)
**AS15169** — Google (cloud/datacenter)
**AS701** — Verizon Business (commercial ISP)
**AS22394** — Cellco Partnership (Verizon Wireless / mobile)
When a platform sees your IP address, it can instantly look up which ASN it belongs to. That ASN lookup reveals the network type, the operator, and the geographic region — all without any cooperation from you.
How IP Addresses Are Classified
Based on the ASN and additional network intelligence data, every IP address falls into one of several classifications:
Residential IP
Assigned by consumer internet service providers (Comcast, Spectrum, AT&T, etc.) to home connections. These IPs are associated with physical home addresses and are considered the most "natural" connection type for individuals.
Platform trust level: High. A residential IP strongly suggests a real person at a real location.
Commercial / Business IP
Assigned by ISPs to business customers. These come from the same ISPs that provide residential service, but through business-grade plans. The ASN is often the same, but the IP range is classified differently in network intelligence databases.
Platform trust level: High. A commercial IP suggests a business operating from a real office location. This is the ideal IP type for business accounts.
Datacenter IP
Assigned to servers in cloud infrastructure (AWS, Google Cloud, DigitalOcean, Hetzner, OVH, etc.). These IPs are clearly identified by their ASN as belonging to datacenter operators.
Platform trust level: Low. Datacenter IPs are associated with automated systems, bots, scrapers, and proxy services. A human user connecting from a datacenter IP is unusual and raises questions.
Mobile IP
Assigned by mobile carriers (Verizon Wireless, T-Mobile, etc.) to cellular devices. Mobile IPs are typically part of large shared pools and change frequently.
Platform trust level: Medium. Mobile IPs are legitimate for individual use but are also used by mobile proxy services that sell access to their IP pools.
VPN / Proxy IP
IP addresses belonging to known VPN providers (NordVPN, ExpressVPN, etc.) or proxy services. These are identified through ASN lookup (many VPN providers operate their own ASNs) and through commercial IP intelligence databases that maintain lists of known VPN exit nodes.
Platform trust level: Low to Very Low. VPN IPs signal that the user is actively hiding their real location and network identity. For business verification, this is a negative signal.
How Platforms Use ASN Lookup
When you access a platform, your IP address is checked against network intelligence databases in real time. The lookup returns:
**ASN and operator name** — who runs the network
**IP type classification** — residential, commercial, datacenter, mobile, VPN
**Geographic location** — estimated physical location
**Risk score** — based on the IP's history and classification
**Known proxy/VPN flag** — whether the IP is associated with anonymization services
This information feeds into the platform's risk scoring system. It is not the only signal — platforms also check device fingerprints, account history, and behavior — but network identity is one of the foundational layers.
What Platforms Actually Do With This Data
Amazon Seller Central checks IP type during account creation and ongoing access. Datacenter IPs trigger additional verification steps. VPN IPs may trigger account review. Multiple seller accounts accessed from the same ASN range are flagged for association.
Stripe uses IP intelligence as part of its Radar fraud detection system. Merchants connecting from high-risk IP types (datacenter, known proxy) may face additional verification requirements.
Banks and payment processors check IP type during login and transaction authorization. Connections from datacenter IPs or known VPN services can trigger step-up authentication or transaction holds.
Why Datacenter IPs Are a Risk Signal
The association between datacenter IPs and risk is not arbitrary. It reflects real usage patterns:
Bot traffic: The vast majority of automated bot traffic — scrapers, account creation bots, credential stuffing attacks — originates from datacenter IPs. Cloud servers are cheap, disposable, and easy to scale.
Proxy services: Many proxy and VPN services route traffic through datacenter servers. When a platform sees a datacenter IP, there is a meaningful probability that the user is hiding behind a proxy.
No physical presence: A datacenter IP tells the platform that the user is not connecting from a physical home or office. For business verification, where the goal is to confirm that a real business operates at a real location, a datacenter IP undermines the entire premise.
This does not mean that every datacenter IP is malicious. Businesses legitimately run applications on cloud infrastructure. But when a human user's browser session originates from a datacenter IP, it is statistically anomalous and triggers additional scrutiny.
Why Commercial ISP Connections Are Trusted
The opposite end of the trust spectrum is a commercial ISP connection. When a platform sees a connection from a business-grade ISP plan, the signals are:
**Real physical location**: Business ISP service is provisioned to a physical address
**Verified customer**: ISPs perform identity verification when provisioning business accounts
**Stable connection**: Business ISP connections have static or semi-static IPs, providing consistent network identity over time
**Low abuse association**: Business ISP IP ranges have historically low rates of abuse, spam, and bot activity
A commercial ISP connection from a recognized regional or national provider is the strongest positive network signal a platform can receive. It says: "This connection comes from a real business at a real address, verified by the ISP."
How to Check Your Own ASN
You can check what ASN your current connection belongs to using several free tools:
whatismyipaddress.com — Shows your IP address, ASN, ISP name, and estimated location.
bgp.tools — More technical, shows the full ASN details and IP range.
ipinfo.io — Provides IP type classification (residential, datacenter, VPN, etc.) along with ASN data.
What to look for:
**ISP name**: Does it show your actual internet provider, or a cloud/VPN provider?
**Organization**: Is it a residential/business ISP or a datacenter operator?
**Type**: Is the IP classified as residential, business, hosting, or VPN?
If your connection shows a datacenter ASN (like AWS or DigitalOcean) or a VPN provider name, platforms see the same information and adjust their risk scoring accordingly.
Why VPN IPs Are Flagged
VPN services are designed to mask your real IP address. For privacy, this is valuable. For business verification, it creates problems.
Known VPN ASN ranges: Major VPN providers operate their own ASNs or lease IP blocks from datacenter providers. Network intelligence databases maintain comprehensive lists of IP ranges associated with VPN services. When your connection exits through a VPN server, the IP is often instantly identifiable as a VPN endpoint.
Shared IP pools: Most VPN services route thousands of users through the same exit IPs. These IPs accumulate negative reputation from the aggregate behavior of all users — including those using the VPN for spam, scraping, or fraud. Your clean behavior does not offset the reputation of the shared IP.
Geographic inconsistency: If your account is registered to a Wyoming business address but your IP geolocates to a VPN server in Amsterdam, the inconsistency itself is a signal. Platforms expect geographic alignment between the account's claimed location and the connection's actual location.
Active evasion signal: Using a VPN tells the platform that you are actively trying to control what network information they see. For a business account, where transparency and verifiability are expected, this contradicts the trust model.
The Network Layer in Context
Network identity is one layer in a multi-layer verification system. It does not operate in isolation:
A residential IP from a location that matches your business address is a strong positive signal
A datacenter IP combined with a CMRA address and a new account is a strong negative signal
A commercial ISP connection from the same city as your state filings reinforces your business identity
A VPN connection from a different country than your registered business raises questions
The practical takeaway: your network connection is part of your business identity, whether you think about it or not. Platforms use it as a signal, and the signal matters.
