What is a reverse DNS search?
In order to find the name of the Internet domain associated with a specific address of the Internet protocol (IP), a procedure called reverse DNS search can be used. This procedure uses a system called Domain Name (DNS) system, which connects the number of domain names such as example.com. Further search can reveal the name of a person or entity to register a specific domain name and in some cases contact information.
A person can use a reverse DNS search when he knows the number IP address of the site and wants to know the name of the domain related to it. In this case, one uses an Internet tool or a website to enter an IP address that is a number of numbers separate periods, for example 123.456.123.456. Until the designers of the website enable the correct records of the pointer in the programming programming for the server domain name, the request sent to a specific IP address will return the correct information. This is the essence of the and reverse DNS search, also called reverseDNS (RDNS).
Reverse DNS is also used to determine e -mail spam. E -mail users are often flooded with unwanted e -Maly called spam. Some internet e -mail servers use a technique called Forward confirmed Reverse DNS search to help you earn spammers who could broadcast undesirable e -mail to millions of people at once. This confirmed reverse DNS search means that a request about a specific IP address is sent, but it is a step further in the fact that the result is then verified to make sure that the relationship is valid.
Every computer that connects to the Internet does so via the Internet protocol address. With the right hardware and software, this unique address can be traced to a specific computer anywhere on the planet. However, numerical domain names can be difficult to remember and numbersAnd they are used to rout the domain name on its numerical IP address. A series of alphanumeric domain names is called a domain name or DNS system.
Separate database, called Whois, keeps contact information for technical and administrative contacts for domain names registered in DNS. In addition, WHOIS provides contact information for IP block owners. Searching similar to reverse DNS search reveals a person or entity that owns a domain name or IP addresses.
