Reverse DNS Email
October 6th, 2011The Domain Name System or DNS is the connecting link between sites and information associated with domain names. By doing this, it functions as a kind of directory. In the DNS, the common URLs that we see for websites (http://www.example.org) are converted to an IP address. This conversion has to take place for the network to function correctly and it also plays a big part in ranking and search engine optimization. Because of the multitude of functions that are associated with the DNS, it also allows you to perform a reverse DNS email search or address and email search and we will discuss that in more depth.
There are large amounts of data in the Domain Name System that have to do with email addresses. It has a directory of mail exchange servers and a service that is based on keywords, directing anyone to the right place on the Internet for what they are searching. It also provides the function, as mentioned above, of connecting the IP address with the URL. They can be used interchangeably but a URL is much easier to remember so most people utilize it. Because of the way these work together, though, the possibility of a reverse DNS email search is there.
Just as you could use a telephone number in a reverse phone or reverse cell phone lookup, you can do that with an email. So, you are someone trying to locate a company email but only have the IP address, you can use this to find the way to get to the desired website. As a business owner, you can use this function to locate the URLs and email addresses of those who might be a future client or asset to what you are trying to accomplish. If you have an IP address, you can use this technology to track down the host information or URL that is connected to it. You can also use it to track down where an unrecognizable or unwanted email originated. After you know where it came from, you can make an informed decision about taking the next steps to contact someone or just hit delete and go about your day! You can also use a reverse DNS email lookup to build an authenticator which sift through unsolicited emails, also known as spam, as well as “zombie” computers who automatically generate email.
If you are a business owner and you need to create a reliable list of emails for potential future clients, using this function would be helpful. You might have 85% of the contact list you desire, but you are having trouble obtaining the last few bits of information you need. Now you can simply choose a site that offers the reverse DNS email search service and enter the IP address or name you have. Soon, you will have the URL of the business and often an email address. This will help you complete your list and get started connecting with those folks who could help you make your business a success!
