Answer: Main website of University of Rajasthan is www.uniraj.ac.in, since any academic institute in India have official website with url ac.in; so all websites named like uniraj and with ac.in domain are owned by university. eg: ns1.uniraj.ac.in, result.uniraj.ac.in, daak.uniraj.ac.in etc. If you find any link on www.uniraj.ac.in saying that this is related to University of Rajasthan, you can find that as official website. For example, university is hiring a firm to conduct the filling of examination form and related things. But that firm doesn't have access to main server and firm doesn't give their code to university. So, the work is going on at http://univraj.org; this website is official as of 2017 to 2019. It is not necessary to continue this url with university. If you will talk about any other website claiming that it is giving information about University of Rajasthan that may be correct but not the official one. You can't claim anywhere that it is owned by University of Rajasthan. sites.google.com/view/ru0 is also a website which is completely copy pasted from main website. It's main purpose is to archive information and avail the information in google search, as main website doesn't do so.
