It turns out that the search engine Bing can do a reverse search by IP-address. Enter a request of the form [IP: 123.123.123.123] - and get a list of sites on this IP.

The list of sites with the same IP address means that they are all physically located, most likely, on the same server. Thus, you can recognize your "neighbors" by hosting.

Keep in mind that neighbors must be chosen wisely. If any spammers are sitting on your IP, it won’t do any good.
Large sites, of course, do not have any “neighbors” for hosting, because they are located on one or several dedicated servers. But here, Bing can show something interesting. For example, for Habrakhabr [
IP: 62.213.122.2 ], he issues a list of approximately 34,400 registered users. And the order of issue is clearly chosen not by chance, but by the rating of incoming links to each profile. That is, this is an alternative rating of users of Habrahabr. In the first place is the habrauser
xaoccps , which is also a leader in the
ranking of habraudes . But further there are obvious discrepancies, and Bing, perhaps, reflects reality better than its own rating on Habré.
Entering inquiries from 62.213.122.2 to 62.213.122.6, one can see other Topical Media projects, including “secret”.
In general, the function of reverse IP search is in various homeowner services, but among the search engines Bing is the only one who can show this. By the way,
he inherited this feature from MSN / Live.
