Investigator Use
IP Address (ipaddress.my) is a web-based IP address lookup and diagnostic tool that provides geolocation data, ISP identification, hostname resolution, and connection information for any queried IP address or domain. It also shows the user's own IP address, useful for verifying anonymization tools during OSINT operations.
For OSINT investigators, ipaddress.my serves as a quick geolocation and ISP attribution tool for IP addresses encountered during investigations. The interface is simple and accessible, providing city-level geolocation estimates, country codes, ASN numbers, and ISP names for any queried IP without requiring account registration.
The tool's self-IP display function has a specific operational security application — investigators using VPNs, Tor, or proxy services can verify that their actual IP address is properly concealed by checking what IP ipaddress.my reports before conducting sensitive research. This verification step ensures operational anonymity is maintained before engaging with investigation targets.
IP geolocation and ISP attribution provides context for IP addresses found in investigation sources. Knowing whether a suspicious IP belongs to a major cloud provider, residential ISP, hosting company, or VPN/proxy service affects how the IP should be interpreted and what follow-up investigation is appropriate.
For fraud investigations, ISP identification can reveal when an IP belongs to a residential broadband provider (suggesting an actual user's home connection), a data center (suggesting hosted infrastructure or VPS), or a known VPN/anonymization service (suggesting deliberate identity obfuscation).
ipaddress.my's domain-to-IP resolution allows investigators to query a domain name and retrieve the resolved IP with associated geolocation and ISP data in a single step, useful for quickly assessing where a suspect domain is hosted.
Limitations: GeoIP databases have accuracy limitations at city and neighborhood levels. City-level geolocation for IPs in some regions may be inaccurate by hundreds of kilometers. ISP attribution is generally more reliable than precise location. Always use multiple geolocation sources for critical location findings and treat IP geolocation as an indicator rather than a precise location.
Record all queried IPs, returned geolocation data, ISP information, and query timestamps in case documentation.
