WHOIS 128.138.188.172



On this page you can find the WHOIS details of 128.138.188.172.



Whois refers to the CLI-tool, which looks like

`whois 128.138.188.172`

and can be used to query the database. The output is similar to the output you get on this website when using the form.

What we basically do, is run the whois command for you and present you with the result. This way, you won’t have to be bothered with downloading and installing the tool. The result will be presented in a somewhat human-readable format, but you will encounter a lot of variation as it lacks a global structure. So, interpretation is still needed.

Fortunately, with some effort, it will give you good insight on who is behind a certain IP-address in case our other tools don’t provide you with enough detail. In most cases, it will also give you clear directions on where to send your complaint in case of abuse coming from the specific address.

Note: Only use this information for your own research. To prevent abuse and misuse of this information, we've also limited the amount of daily requests you can do.
