Private Mirror

Good Afternoon, I need to setup a private repo for rawhide I was told that is about 200gb. I am looking at the documentation for private mirrors and they are not clear on the way forward on how to get this setup. Is this the right place to ask and seek assistance? Also Im noticing that you require a netblock even for private mirrors. Is this absolutely necessary as my VPS provider gives me a single IPv4 but i can get a whole /64 ipv6 netblock assigned if necessary. Looking forward to hearing back from you. Regards, Jonathan
