What does an IP address lookup show?
An IP address lookup shows the public details behind an IPv4 or IPv6 address, including location, timezone, ISP, organization, ASN, reverse DNS, detection flags, and threat score
How to read IP location, ISP, ASN, and proxy signals
Residential or ISP network
Mobile flag
Hosting flag
Proxy or VPN flag
Tor flag
Threat score
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.
