Today I’d like to introduce to you:, my latest project.

It’s a little web app where you can search for an IP, an Autonomous System number or a domain name to find information about those.

Although I’m perfectly aware of the fact that there are already numerous tools out there that have similar functionality, I started with developing  It began mainly a an exercise in Golang, internet technologies in general and, most importantly, for fun.

But the topic was not randomly chosen: I always had to copy & paste information for an IP from different sources until I had all the information I needed together when working at my day job.

So I also did it to have a tool at hand to which I can throw IPs, ASN Numbers, domain names, etc.. and it would always respond something

In this first public release I’m not quite there. MAC addresses, for example, are not yet supported (but will be once), Whois information is not yet as complete as I’d like it to be (getting correct Whois information is not as easy as I thought, but that’s enough material for another post.) and It’s not yet possible to search for companies and get their assigned AS Numbers back. (but it’s planned as well.)

Also I plan to provide an API for all the information you can now see in the results of a query for easy access in your apps.

Nevertheless I’m happy with the result so far and I’ll keep improving the site continuously.

If you have the time and like using, I’d be very happy to hear from you and receive feedback. Maybe you have an idea that could make more useful for you? Maybe something about it totally sucks and I better change it? Let me know: is on twitter, has a simple contact form for feedback or you may simply leave a comment below.

Hope to see you on,
