Six data points returned for every IP address lookup
Geographic location
Country, region, and city-level location. Accurate to ~50km for most residential IPs. Pinpoints data centre IPs precisely.
ISP & organisation name
The internet service provider or company that owns the IP range. Identifies VPN providers, cloud hosts, and business networks.
Abuse reputation score
Whether the IP has been reported for spam, port scanning, brute-force attacks, or hosting malware — pulled from major abuse databases.
Autonomous System (ASN)
The network operator responsible for routing traffic for this IP — useful for identifying botnets and malicious hosting providers.
Hostname (reverse DNS)
The domain name associated with the IP. Often reveals the server's purpose — mail servers, CDNs, cloud providers, or suspicious infrastructure.
VPN / proxy / Tor detection
Whether the IP belongs to a known VPN exit node, Tor relay, or anonymous proxy — indicating the real user location is being hidden.
Real situations where an IP lookup gives you the answers you need
Suspicious email from unknown sender
Check the originating IP from the email headers to see if it's from a flagged server or unexpected country. A UK bank email coming from a Nigerian IP = phishing.
Unknown IP in your server logs
Repeated requests from an unfamiliar IP? Look it up. If it's a data centre in a country you don't serve, or listed in abuse databases, block it at your firewall.
Failed login attempts on your account
Most security dashboards show the IP address of failed login attempts. Look up the IP to understand whether it's a targeted attack or automated botnet.
Received a suspicious message online
If someone gave you an IP address in a message (or you obtained it from a connection), look it up to understand where the person is connecting from.
Verify your VPN is working
Look up your own IP address while connected to a VPN. If the result shows the VPN server location (not your home country), your VPN is working correctly.
Research a website's hosting
The IP of a website's server reveals its hosting provider and data centre location — useful for investigating suspicious domains and fake shops.
IPv4 e.g. 192.168.1.1
The original IP format — 32 bits, written as four groups of numbers separated by dots. There are approximately 4.3 billion IPv4 addresses, most of which are now allocated. If you see an IP address in a suspicious email or log, it is most likely IPv4.
IPv6 e.g. 2001:db8::1
The newer format — 128 bits, written as eight groups of hexadecimal numbers. IPv6 provides 340 undecillion addresses. Increasingly common as IPv4 addresses run out. Our lookup supports both formats.
An IP address (Internet Protocol address) is a unique numerical label assigned to every device on the internet. Looking up an IP address can reveal: approximate geographic location (country, region, city), the internet service provider (ISP) or organisation that owns the address range, whether it belongs to a data centre, VPN service, or proxy, the autonomous system number (ASN) of the network operator, and whether the IP has been reported to abuse databases for spam, hacking attempts, or malicious activity. It cannot reveal a specific home address or the personal identity of the user.
Your public IP address is assigned by your internet service provider and is visible to every website you visit. To find your own IP address, simply search "what is my IP" in Google, or use our IP lookup tool. Your IP shows your approximate location and ISP. If you use a VPN, your visible IP address will be the VPN server's address rather than your own.
IP address lookup returns: geographic location (country, region, and city-level — accurate to within ~50km for most residential addresses), the ISP or company that owns the address range, whether it belongs to a data centre or VPN provider (indicating someone may be masking their location), the reverse DNS hostname (often reveals the server's purpose), abuse reputation (whether the IP has been reported for spam, port scanning, or attack attempts), and the autonomous system (AS) number identifying the network operator.
If you see an unknown IP in your server logs or firewall, a lookup can help identify the threat. Data centre IPs probing your server are often automated bots scanning for vulnerabilities. IPs from known-bad autonomous systems (botnets, hosting abuse) should be blocked. Repeated connection attempts from a single IP are usually brute-force login attacks. Our IP lookup checks against abuse databases so you can make an informed decision about whether to block the IP.
A flagged IP has been reported to abuse databases (AbuseIPDB, Spamhaus, and similar) for sending spam, conducting port scans, attempting brute-force logins, hosting malware, or other malicious activity. For email: if the sending IP is flagged, the email is almost certainly malicious — do not click any links. For server logs: block the IP at your firewall. For consumer use: if someone gave you this IP and it's flagged, treat any communication from that source with extreme caution.
Yes. Enter your own IP address into the lookup to see exactly what information is publicly visible about your connection — location, ISP, and whether your IP has been associated with any abuse reports. This is useful to understand what tracking websites can infer about you, and to verify whether a VPN is successfully masking your real location.
