Reverse DNS is the process of translating the IP addresses to the host names. It is the duty of the reliable web hosting company that you hire to provide the reverse DNS feature.
Reverse DNS provided by the reliable web hosting is just the reverse of the forward DNS. In forward version of DNS, the internet name is submitted to the domain name severs system. The system returns the IP address of the website submitted. When you host a website on the server of the reliable web hosting company, your website is given a unique number. This number forms the IP address of the website. It is necessary that the IP address is unique to every website. Other wise the website will not be identified. But the drawback of IP addresses is that it is not possible for the humans to remember the numbers of so many website. Thus, for the convenience of the humans, every website is also given a name in regular English language by the reliable web hosting. This is called the domain name of the website and is an important concept in emarketing.
In forward DNS, the users type the domain name of the website in the URL of the web browser. This name is sent to the domain name system. Using the forward DNS, the domain name is converted by the reliable web hosting company to its corresponding IP address which can then be used to locate the website. This is the case with the forward DNS.
In reverse DNS, the IP address is submitted to the DNS system of the reliable web hosting company and it returns the domain name of the website. This application is not of much use as far as identifying the website is concerned. Even if the reliable web hosting company that you have chosen does not provide the reverse DNS services, it will still uniquely identify the website and there will be no problem in loading the web pages on the web browser of the users. But if the reliable web hosting company provides these web services, it can come in very handy.
One of the main applications of the reverse DNS is in analyzing the traffic coming to a website. It logs the incoming traffic. When the visitor visits a website, the domain name of the website accessed by the users is taken into account with the help of reverse DNS. In this log maintained by the reliable web hosting company, when the users visit any ecommerce website, the domain name is noted. This can be later on used to find the number of visits to a website and thus can give an idea to the web merchants about the popularity of the website.
Another application of this service provided by the reliable web hosting company is to prevent the spread of spam mails. With the help of the reverse DNS, the reliable website hosting company can verify whether the email is actually coming from the address that it claims to be. If the reliable web hosting that you choose does not provide this service, you will face problems with r-commands, IRC and even in the case of the SMTP servers.You can search web hosting Australia for a list of providers available to you.
