Reverse IP address lookup

Reverse IP

When a website address is given,you can easily find its IP address(Given website address DNS servers can get IP address)  Just do a ping and it will return the IP address (For example, In the command prompt, type "ping yahoo.com" it will return IP address of yahoo.com) But is there a way to list all websites hosted in a particular IP address. The process of finding this is termed Reverse-IP.

Without direct admin access to the webserver, we cannot directly find the sites hosted in it. Indirect method used is to have a web crawler (like that of search engine) list all the websites with same IP address. If any site is not made public or is not accesible to webcrawler then those sites wont be listed.

Given below is few sites providing Reverse IP 

1) whois.webhosting.info : find the ip address of one of the sites and enter it into this site, it will list all sites hosted in that webserver

2) Bing Search : There is a search operator( IP: ) available in Live search, which can be used to do Reverse IP. So the search string to do this is IP:xx.xx.xx.xx (replace xx.xx.xx.xx with IP  address of one of the sites)

3) YouGetSignal : I think it is using Live Search method (discussed above) behind the scene . but still it is useful, since all the results are displayed in one long page.
