We recently launched a free tool that shows a summary of the top cities, countries, asns, routes and much of the other context that we (IPinfo) have for any IP addresses you paste into it.Sample results:  can paste any arbitrary text into the tool at  and we'll extract the IPs.It can be useful for getting a quick summary of a set of IPs (eg. click on first google result for "public proxies", copy and paste the results into the tool, and see where the proxies are located, and the networks they're on), for investigating issues (eg. your website gets a large spike of traffic, paste the recent IPs from your access log into the tool and see if there's a specific network that stands out), threat investigation, debugging and more.We're planning to add more functionality and data points in the near future, and any feedback or suggestions are very welcome!
