What this IP lookup tool shows
This page gives you a practical technical profile for an IP address. It helps you understand where the IP is registered, which network appears to own it, and whether there are signs of proxy use, hosting infrastructure, or blacklist-related risk.
That makes it useful for security reviews, support work, moderation, infrastructure research, and quick troubleshooting.
Why it matters
Looking up an IP can help you add useful context quickly, especially when location, network ownership, or risk signals matter.
What does an IP Lookup tell you?
An IP lookup queries geolocation databases and network registries to return information associated with a given IP address. This includes the country, region, and city, the ISP or hosting provider, and the ASN.
Beyond location, a thorough lookup also checks whether the IP is flagged on DNS blacklists, associated with VPN or proxy services, or linked to malicious activity.
IPv4 vs IPv6 โ what's the difference?
IPv4 addresses are 32-bit numbers written as four decimal octets, such as 8.8.8.8.
IPv6 uses 128-bit addresses written in hexadecimal, such as 2001:4860:4860::8888. Both formats are supported.
What is an ASN?
An Autonomous System Number (ASN) identifies a network operated by a single organisation, such as an ISP, cloud provider, or large corporation.
Common uses for IP lookups
- Security investigations โ identify suspicious traffic or login attempts
- Fraud prevention โ detect VPNs, proxies, and Tor exit nodes
- Network debugging โ verify routing and identify the owning ISP
- Content compliance โ confirm geographic restrictions
- Email deliverability โ check whether a mail server IP is blacklisted
How accurate is IP geolocation?
IP geolocation is generally accurate at the country level, but less precise at city level. Accuracy degrades for mobile IPs, satellite connections, VPNs, and CDN edge nodes.
For most use cases, country and ISP data alone is highly reliable. City-level data should be treated as an estimate.
What is a DNSBL (DNS blacklist)?
A DNS-based Blackhole List (DNSBL) is a real-time database of IP addresses known to send spam, host malware, or engage in other abusive behaviour.
Frequently asked questions
Can I look up my own IP address?
Yes โ visit the What Is My IP page to instantly see your current public IP address.
Is the IP Lookup tool free?
Yes. It is completely free and works without an account.
Does this tool support bulk IP lookups?
The web tool supports one IP at a time. For bulk lookups, use the free IP API.
Why can an IP show the wrong city?
City-level geolocation is an estimate and may reflect a network hub, provider office, VPN endpoint, or mobile routing location.
