Our internet policy blocks so-called 'parked' websites, i.e. those that are registered but do not seem to be active. I'm not sure what tests are used to determine parked status.
There is a tool that my team is looking to use but some of the documentation is on a domain that our filter software has flagged as 'parked' and therefore is inaccessible.
I'm struggling to understand what risks are associated with such 'parked' websites that wouldn't exist for any other type of website. Is the logic here that these sites are useless so why allow access? Have such sites been used historically in attacks? If there are risks, what should constitute a 'parked' website? In this case it seems that all of the 'front-page' documentation was moved to a different domain but some of the deeper detailed artifacts were left behind at an older domain. I would like to better understand how to address this and mitigate any risks.
