Public where it has to be, private where it should be.
Your machine receives its own public IPv4 and IPv6 along with reverse DNS you control. You place the machines that only talk to each other on a private network, keeping them off the open internet.
VPS VDS Dedicated
Two paths into the same machine
Your visitors arrive on the public address. Your other machines connect through the private address on a range you choose, and their traffic never leaves the region.
The addresses you get
You find all three on the machine's networking screen, and you write the third one yourself.
Private networks
You give a network a name and a range, attach your machines to it, and they reach each other on internal addresses. Their traffic stays inside the region instead of crossing the public internet to reach the machine next door.
- You pick the name and the address range yourself.
- The console builds the network in the machine's own region so it can actually join.
- You run up to five private networks on a single machine.
- Detach your machines and the network cleans itself up when nothing remains on it.
You only set reverse DNS on an address the machine actually holds. The console checks the address against the machine before it writes the record. This means it refuses a typo rather than silently pointing at someone else's server.
Frequently asked questions
Do I pay extra for IPv6?
No. Every machine gets an IPv6 address alongside its IPv4 address. Neither arrives as a billed add-on.
Why would I set reverse DNS myself?
Mail servers check your PTR record. If you send mail from the machine, a record that matches your sending name makes the difference between arriving and landing in spam.
What is a private network good for?
Keeping a database off the public internet remains the most common reason. You put your database and your application on the same private network, leaving the database completely hidden from the outside.
Can machines in different regions share a private network?
No. A private network stays inside one region, which is what keeps it fast. Your machines in two regions talk over their public addresses, and you write a firewall rule that specifically names the other server.
Does a dedicated server get networking features?
It gets the public side, including its own addresses and its own reverse DNS. Private networks run on cloud fabric, so you only find them on a VPS or a VDS.
