A reverse IP address search (Internet protocol address)  is performed when you have identified a person’s IP address, but want to find out additional information about the user of the IP address. Most reverse IP address searches can provide websites, domains, owners and much more. Below I’ve listed what I believe to be the best source (Free or paid) for performing a reverse IP address search.

Domain Tools: Every member of Domain Tools (even free ones) can order Reverse IP lookups as a report. You will be able to download a full list of domains on any IP address; even IPs with over 1 million domains. Reports make it easier for you to sort and parse through the list of domains.

Reverse email searches are performed when you have an email address, but don’t know the owner’s name. Very helpful if you need to track down friends, associates or an unknown email sender. Below I’ve listed what I believe to be the best free sources for reverse email searches.

Yahoo People Search: Very simple site that doesn’t distract from your reverse email search.

Reunion: A free service that has unbelievably accurate results for a number of categories including reverse email address searches.

Employers often need to verify social security numbers for tax purposes. As an individual you may find the need to perform a social security search aside from work. Unfortunately, public databases do no list social security numbers due to identity fraud, and misuse of this sensitive information. However, if the social security number you are searching for belongs to a deceased person you can get his or her social security number for free by simply looking up their name. Below I’ve listed what I believe to be the best free source for conducting a social security search.

Social Security Online: Social Security Online is a free service provided by the United States Government. This is your one stop powerhouse for all your social security needs. This is a great place to start a SSN search.
