No your domain IP 91.83.235.2 does not redirect to sifu.hu If the IP address is on a shared web server where multiple websites share the same IP, it is natural that the IP address alone does not redirect to a specific domain name. In this case, the IP address is not directly assigned to your website but is a general shared IP address serving all the websites hosted on that server. This does not cause any issues by itself and does not affect search engine rankings.
To check this for your website, enter your IP address in the browser and see if your site loads with the IP address.
Ideally, the IP should redirect to your website's URL or to a page from your website hosting provider.
If it does not redirect, you should do an htaccess 301 redirect to make sure the IP does not get indexed.
