What makes Reverse DNS Search Sites Used

A reverse DNS (domain name server) lookup is similar to a reverse telephone search in that it is designed to find information associated with a group of numbers. However, unlike a reverse telephone search that lookups a telephone number, a reveres DNS search conducts a search with an IP address. An IP (internet protocol) address is a computer's numeric address (I.E. 1.0.30.36) which is converted into a domain name (I.E. Domain.com) by a DNS. Every server that is attached to the web has a unique Internet protocol address. For that reason, a reverse DNS lookup queries domain name servers in an attempt to find a match . Why is a reverse DNS lookup utilized? A reverse DNS search can be utilised for several reasons, but the most common reasons are:

-Network troubleshooting support - Reverse DNS lookup was very beneficial for SMTP e-mail, and website resources utilized to track users, for instance, in the case of web discussion boards. Basically, reverse domain name lookups provided assistance in a similar that tracerouting and pinging is useful regarding network support.
-Anti-spam - This service is usually utilised by visitors to check into the domain name of a certain sender of junk mail emails, in order that it can be determined whether the spammer is likely connected to dialup clients, home-based broadband clients, or if the individual has dynamically assigned addresses. A lot of, but not all, junk mail emails start off from servers that have missing "generic" reverse domain name server search names.
-Verifying the Forward Confirmed reverse DNS (FCrDNS) format - This verification in FCrDNS format allows a method of authentication that is connected between the server proprietor, IP address provider, and the domain name proprietor. Although this method is just not completely thorough, it is accurate enough in validation that it is often utilized for white-listing, as lots of junk emailers and phishers use "zombie computers" that could not escape this sort of a test. Thus, if you'd like to match an Internet protocol address with a domain name server, all you will need is the Internet protocol address, that you will get into the search box provided on a Reverse DNS search website. With any luck you'll achieve successful results.
