Yeah, you want me to pay 50k for someone to manage hostnames? *clap*
Devices change networks, they aren't always on the same network. If you're building your entire system based around nothing changing, when it does, everything shits the bed. There is dynamic IP allocation for a reason. Unless you're talking about a static part of the network that never changes (like a router or managed switch), this is silly. Once you get past 10 rigs you'll start to figure that one out on your own.
No meter. DHCP is a must in farms or you are doing it wrong, unnecessary effort.
You don't have to pay any K and don't have to manage hostnames or change computer names or anything in Windows at all, you just don't understand what DHCP is, google it. If you have some basic IT skills, you may learn and DIY from Youtube. Dynamic IP allocation is for everyday users, not for industrial cases.
When someone with expert skills is trying to help you and give you a "million dollar advice", please don't argue, just take it. And be sure I manage many times more then just 10 rigs and do least effort in the process.
P.S. I am ready to help anyone else in farm automatization, just PM me (no off topics here).
