LookMyIP
A free, fast, and privacy-friendly set of network tools — built for developers, sysadmins, and anyone curious about IP addresses.
Tools
IP Address Lookup
Instantly find location, ISP, ASN, timezone, and network details for any IPv4, IPv6, or domain name. Auto-detects your own public IP on load.
IP Blacklist Check
Check if any IP address is listed on major spam and abuse blacklists including Spamhaus, Barracuda, SpamCop, and SORBS via DNS lookups.
Privacy
LookMyIP does not store any IP addresses or lookup results. Every query is processed in real time and discarded immediately after the response is sent.
We use anonymous usage analytics (Mixpanel) to understand which features are most used. No personally identifiable information is collected or sold.
Rate limiting (10 lookups per minute per IP) is enforced in memory only and is not persisted to any database.
