I want to provide users with sub domains on my website.
Users will provide an ip address and the sub domain they want and I will then use a DNS service to redirect to that IP through an A record or CNAME record.
Apart from the obvious risk that the user performs something nefarious with the sub domain (eg. hosting illegal material etc), is there any risk that the individual could use this to hijack the root domain?
The root domain is just static HTML, if this changes anything. Thanks!
