Reverse Lookup with Bing

I learn this unique feature at Microsoft latest search engine, Bing.

You may perform reverse lookup with an IP address for a main site and generate a list of sub-site with Bing search engine.

For example, you enter "ip:216.34.181.45" (without the quote). This is the IP address for SlashDot main. It will results in 310,000 answers with a list of sub-site that hosting at the same public IP address.

This is a great feature as it can allow a pentester to find out how many websites are hosted at one particular IP address during reconnaissance. Cool!
