Web hosting is an online service that enables you to publish your website or web application on the Internet. When you sign up for a web hosting service, you basically rent some space on a physical server where you can store all the files and data necessary for your website to work properly.
It is very easy to find out the hosting of any site, as well as detailed information about its registrar - for this you just need to enter the domain address or its IP address into a service called Whois. With its help, you can find out where the domain is registered, whether it is occupied and to whom it belongs. In addition, using Whois, you can check the health of the site and find out information about the DNS server.
A service that allows you to determine which provider a particular IP address belongs to is called a "whois service". Do not be intimidated by unfamiliar words: using this service is sheer pleasure. Moreover, it is completely free and does not require registration.
Find out website hosting by domain
This method can be attributed to perhaps the most popular method described on the Internet. Its essence is simple: it suggests using a whois service to find out which hoster's DNS is used to maintain the domain of the site of interest to us, and then assume that the capacities of the same hoster are probably used to ensure the site itself is operational. Unfortunately, the truthfulness of the information about the hosting of the site obtained in this way is not great.
The thing is that the domain of the site and the site itself can be located at different hosting providers, for example, if the owner of the resource likes the quality of hosting from one hoster, and the prices for renewing domains - from another.
Find out website hosting by 403 or 404 error pages.
This method of determining the hosting is designed so that if the owner of the site you are interested in has not made his own web server error pages for him, then when you call them you will be able to see the hosting provider's default error pages (if this hoster has them, of course there is). The disadvantage of this method lies in the fact that often small hosting companies simply do not have their own web server error pages. And even more often it happens that the site has its own error pages or that when you try to open a non-existent page on a site with a CMS, the system simply hides the error page provided by this CMS by default.
IS IT POSSIBLE TO HIDE THE SITE HOSTING
Can. Of course. If the site owner does not want someone to know what hosting his site is on, he will take all possible measures for this and determine the hosting of such a site will, alas, be impossible without having good technical knowledge.
Fortunately, there are very, very few such sites. Therefore, the likelihood that you will find yourself in an impasse is extremely small.
In this article, we will not consider in detail how to hide the hosting of your site, since this is a completely different story, which will require a whole article to consider, but still we will tell you about a few of the simplest ways.
Firstly, to hide the hosting of the site, you can use any CDN service that, using a CDN proxy that passes traffic through itself, will hide the real IP address of the site. Secondly, you can take the hosting itself from one provider, and use the IP address of another provider. Thirdly, the site can be hosted on a dedicated hosting server with its own subnet of IP addresses and BGP can be configured to be used to route its own AS by setting BGP peers in advance. In short, there is always an option to hide hosting. There would be a desire :)
