IP Address Lookup
Look up the location, ISP and network of any IP address.
Your IP just told us where you are.
Every site you visit sees the same thing. JaguarVPN replaces your IP and location with our server’s — so websites, advertisers and your ISP can’t track or profile you.

Frequently asked questions
What is an IP address lookup?+
It resolves an IP address to its approximate location (country, region, city), the internet provider or organisation that owns it, and its network (ASN) — useful for checking where a connection comes from.
Can I look up any IP address?+
Yes. Enter any public IPv4 or IPv6 address. Leave the field blank to look up your own IP. Private/reserved addresses return no location.
How accurate is IP geolocation?+
IP geolocation is accurate to the country and usually the city/region, but not to a street address. It reflects where the ISP routes the IP, which can differ from the user’s exact location.
Does an IP reveal a datacenter or VPN?+
Often, yes. We flag IPs that belong to hosting/datacenter networks, which is a strong signal the address is a VPN, proxy or server rather than a home connection.
