While a lot of internet infrastructure is build on HTTP, things change occasional even a 301 leads to an 404. If there is at least some DNS entry and a server answering.
A few NXDOMAIN later this led me to the rabbit hole of systematic approaches about abandoned infrastructure.
While domain sniping is so common there is even a Wikipedia entry and is (as far as I observed) often used to farm the traffic for advertisements.
In hindsight obvious, this even effects C&C services. I liked the Watchtowr write up Admins Of .MOBI which then led to Backdooring Your Backdoors.
