IP Address Lookup
Look up any IP address to find its location, ISP, organization, and security details. Enter an IP below or view information about your own IP.
What is an IP Lookup?
An IP lookup (also called IP address lookup or IP search) is the process of finding information associated with an Internet Protocol (IP) address. Every device connected to the internet has a unique IP address that identifies it on the network.
When you perform an IP lookup, you can discover details such as:
- Geographic Location - Country, region, city, and approximate coordinates
- ISP Information - The Internet Service Provider that owns the IP
- Organization - The company or entity using the IP address
- ASN - Autonomous System Number for network identification
- Connection Type - Whether it's residential, business, or data center
- Security Flags - VPN, proxy, or Tor usage detection
Common Uses for IP Lookup
Security Investigation
Investigate suspicious IPs from server logs, identify potential threats, and trace attack sources.
Geolocation Verification
Verify the geographic location of users, customers, or visitors to your website.
Spam Analysis
Identify the origin of spam emails or comments by looking up sender IP addresses.
Network Troubleshooting
Debug network issues by checking IP details and verifying routing information.
Compliance Checks
Ensure users are accessing services from permitted geographic regions.
Research & Analytics
Analyze website traffic patterns and understand visitor demographics.
Frequently Asked Questions
What information can I find with an IP lookup?
An IP lookup reveals geolocation (country, city, coordinates), ISP information, organization name, ASN (Autonomous System Number), timezone, and whether the IP is associated with VPNs, proxies, or data centers.
Is IP lookup legal?
Yes, IP lookup is completely legal. IP addresses are public information assigned by ISPs. Looking up publicly available information about an IP address does not violate any laws.
How accurate is IP geolocation?
IP geolocation is typically accurate to the city level (about 80-90% accuracy). Country-level accuracy is usually 95-99%. Exact street addresses cannot be determined from an IP address alone.
Can I look up any IP address?
You can look up any public IP address. Private IP addresses (like 192.168.x.x or 10.x.x.x) are only used within local networks and cannot be looked up externally.
What is the difference between IPv4 and IPv6 lookup?
Both IPv4 and IPv6 addresses can be looked up the same way. IPv4 addresses look like 192.168.1.1, while IPv6 addresses are longer, like 2001:db8::1. Our tool supports both formats.
Why would I need to look up an IP address?
Common reasons include: investigating suspicious network activity, verifying the location of website visitors, troubleshooting network issues, checking if an IP is blacklisted, or identifying the source of spam or attacks.
