Bing has a pretty cool IP advanced search operator<\/a>. It can be used to detect shared hosting. It is quite annoying to type in each IP manually when you have to check several IPs (e.g. corporate IP network). The following script will scan an entire range of IPs. The examples below (Google IPs 74.125.39.103 to 74.125.39.106) give some pretty interesting results…<\/p>\n

I admit, the getIpRangeList function could be a little bit more elegant, but I didn’t want to use an external library, didn’t find any suitable code snippet and in the end, it does its job.<\/p>\n","protected":false},"excerpt":{"rendered":"
