Can I attach my diverse IPs to a VPS or dedicated server
Yes, and it is how these are usually ordered rather than an unusual request. The address inventory is not tied to any one product, so a virtual server or a physical machine can carry a large allocation at whichever separation grade you chose, with a single billing account and a single support queue covering the lot.
Why the two are separate purchases
Hosting and addressing are sold apart because they grow apart. An estate frequently needs thirty more addresses and no more processing, or twice the memory and not a single new domain. Bundling them would force one to move whenever the other did.
Keeping them separate has a second benefit that matters more over time: the addresses are not a property of the machine. Change the machine and they follow. That is what makes moving between shared accounts, a virtual server and metal a step rather than a rebuild of the separation you paid for.
How it works in practice
- Order the machine, or the account, at whatever size the workload needs.
- Order the addresses separately, at the tier and count the estate needs.
- Bind each site to a chosen address rather than accepting the default order of the list.
- Give each domain its own nameserver pair, pointed at different addresses.
Step four is the one that gets skipped on a dedicated machine, and skipping it undoes a large part of the work. A single machine serving forty domains through one shared nameserver pair has re-grouped them, however carefully the addresses were chosen. The mechanism is set out in Nameservers and DNS.
Mixing tiers on one machine
Nothing requires a machine to carry a single grade of separation. The common arrangement on a large estate is a bulk allocation at the entry tier for the long tail, plus a small number of wider-separation addresses for the properties where being grouped would cost something. Both attach to the same machine and appear in the same panel.
The tier comparison is in IP Classes Explained.
What stays your responsibility
Attaching addresses to your own machine gives you more control over assignment, and with it more room to create a footprint by accident. Two things to watch: addresses left bound to sites that no longer exist, and new sites landing on whatever address was next rather than one chosen on purpose. Both are bookkeeping problems rather than technical ones, and both are much easier to prevent than to unpick later.
