If this sounds like too much information, you’re getting the idea: every website you visit can potentially find out this much about you unless you take proper precautions.

The site also allows you to do a quick look-up of any other IP you might stumble upon, certainly useful in certain situations but not something you can’t do on other sites.

What puts Trasir ahead of these, however, is the sparkly-clean interface and the almost total lack of advertisement: but a single Amazon referral link generates revenue for the service. Overall a site worth using when you need to quickly look up an IP – or see whether or not your proxy is actually hiding you.

Features

• Find out what information websites can see about you.
• Includes your IP address, your host name, your country, your city, and other information.
• Quickly look up data about any IP address.
• Clean interface stays out of your way.
