The line here is extremely blurry: What constitutes a reseller? For example, I rent a private rack in a local datacenter. The equipment is 100% owned and managed by my company, including our firewall and switches. I also have my own /26 (~64 IP addresses). Let's do a bit of research:
[jjbegin@bane ~]$ host rightbrainnetworks.com
rightbrainnetworks.com has address 188.8.131.52
[jjbegin@bane ~]$ whois 184.108.40.206

This tells you who ARIN assigned my netblock to, which is Online Technologies, my datacenter provider. But there's no mention of me or my company. It's because I don't have my own assignment from ARIN, so I'm subletting address space. But all the equipment is owned an managed by me. Does this mean I'm a reseller of the datacenter?
As part of our hosting, we also provide CPanel accounts. A feature of WHM/CPanel is the ability to create sub-accounts. I have one business partner who resells accounts that he sets up and provides first-level support. But I've available for second-level support, which I provide on a routine basis. Is he considered a reseller?
I'm a bit confused on how you can be writing a book on the web hosting business without understanding how nebulous your question is?
