How to read IP location, ISP, ASN, and proxy signals

Residential or ISP network

The ISP and organization fields show which network the IP belongs to. A consumer ISP, mobile carrier, or trusted network usually looks more natural than a generic hosting provider

Mobile flag

If the mobile flag shows “yes,” the IP may belong to a mobile carrier network. Mobile IP locations can be less precise because carriers often route traffic through regional pools

Hosting flag

If the hosting flag shows “yes,” the IP may belong to a datacenter, cloud provider, or hosting network. Some platforms may treat hosting IPs as higher risk than residential or mobile IPs

Proxy or VPN flag

If proxy or VPN shows “yes,” the IP may be associated with proxy or VPN traffic. This can affect trust signals, analytics, fraud checks, or account workflows

Tor flag

If the Tor flag shows “yes,” the IP may be associated with Tor traffic. Some platforms and security systems treat Tor traffic as higher risk

Threat score

The threat score summarizes risk signals for the IP. A lower score usually means fewer detected risk indicators, while a higher score means the IP may need closer review

Common uses for IP lookup and IP location data

  • Proxy verification. Check whether a proxy shows the expected country, city, ISP, ASN, and detection flags.
  • Traffic analysis. Review visitor IPs to understand network origin, hosting status, and suspicious traffic patterns.
  • Fraud prevention. Check sign-ups, logins, payments, or chargebacks against proxy, VPN, Tor, hosting, and threat score signals.
  • Ad verification. Confirm whether ads, landing pages, or localized content are being viewed from the expected IP location.
  • Incident response. Use ISP, organization, ASN, and reverse DNS data to investigate suspicious IP activity.
  • Content localization. Check whether IP location data matches the expected country, city, or regional experience.

Frequently asked questions

An IP lookup checks an IPv4 or IPv6 address and returns public information about it, such as location, ISP, organization, ASN, reverse DNS, and usage type.

You can use NodeMaven’s IP lookup tool to check whether an IP appears as residential, mobile, datacenter, hosting, proxy, VPN, or Tor traffic.

 

IP geolocation is approximate. It can usually identify the country, region, city, ISP, and ASN, but it may not show an exact physical address.

Accuracy depends on the IP database, the network type, and how the ISP routes traffic. Mobile IPs are often less precise because carriers use regional IP pools.

ASN stands for Autonomous System Number. It identifies the network that announces and manages an IP address on the internet.

For example, a lookup may show an ASN connected to Google, Cloudflare, a mobile carrier, a residential ISP, or a hosting provider.

Yes. The IP lookup result shows detection flags for proxy, VPN, Tor, hosting, and mobile traffic when this data is available. These flags help you understand how an IP may be classified by websites, fraud tools, and security systems.

Reverse DNS shows the domain name connected to an IP address through a PTR record.

For example, a public DNS IP may return a reverse DNS result such as dns.google or one.one.one.one. Not every IP address has a reverse DNS record.

Yes. The IP lookup page supports single IP checks, and the designed page also includes batch lookup for up to 100 IPs.

Batch IP address lookup is useful for checking proxy lists, traffic logs, sign-up activity, ad verification results, or suspicious IPs in bulk.

Our IP Lookup tool shows your current public IP address, but it also lets you check any IP address and see additional details such as IP location, ISP, ASN, reverse DNS, usage type, and proxy/VPN/Tor signals.

Yes. NodeMaven’s IP lookup tool is free to use for checking IP address details.

You can use it to check your own IP, review proxy IPs, verify IP location, or inspect public IP information before starting a workflow.

You can find your IP address by using the “Look up my IP” option in the tool.

The page will detect your current public IP and show details such as location, ISP, ASN, reverse DNS, and usage type.

An IP lookup focuses on location and network intelligence, including country, city, ISP, ASN, reverse DNS, and usage type.

An IP checker can be a broader term. It may refer to checking your own IP, testing whether a proxy works, or verifying whether an IP is associated with proxy, VPN, Tor, hosting, or mobile traffic.
