Every dedicated server we deliver comes with one usable IPv4 address. If you need more, the order form sells three larger blocks: a /29 with 5 usable addresses for €8 a month, a /28 with 13 for €26 and a /27 with 29 for €58. This post explains why those usable counts are smaller than the block sizes, what extra addresses are genuinely good for, and how to pick a size you will not have to replace in six months.
The subnet ladder
| Block | Addresses in the block | Usable by your server | Per month | Per usable address |
|---|---|---|---|---|
| /31 | 2 | 1 | Included | Included |
| /29 | 8 | 5 | €8 | €1.60 |
| /28 | 16 | 13 | €26 | €2.00 |
| /27 | 32 | 29 | €58 | €2.00 |
The same ladder applies to every server in the range, from the €209 entry Xeon to the largest EPYC, and the subnet is billed monthly with the server.
Why a /29 gives you five addresses, not eight
A normal subnet loses three addresses before you can use any. The first is the network address, which names the block itself. The last is the broadcast address. And one more goes to the gateway, the router your server sends its traffic through. Eight minus three leaves five.
The included /31 is a special case. It is a point to point link of exactly two addresses with no network or broadcast address: one for our router, one for your server. That is why it is the cheapest way to give a single server a single address, and why it is the default.
Why IPv4 is priced per address now
The regional registries ran out of fresh IPv4 years ago. In Europe the last allocation from the free pool was made in November 2019, and since then new addresses come from the transfer market, where they are bought and sold like any other scarce asset. That is why few providers still hand out a free /29 with every server, and why per address pricing is now the norm. Our price works out at €1.60 per usable address on a /29 and €2.00 on the /28 and /27.
What extra addresses are good for
- Virtual machines with public addresses. If the server runs Proxmox VE, which is on our install list, each guest that faces the internet directly needs its own address. A /28 covers 13 guests, a /27 covers 29.
- Several services on the standard ports. Two separate web stacks that both want port 443, a set of game servers that players expect on their default ports, or separate VPN endpoints are all simpler with one address each.
- Separating customers. Agencies and small hosting resellers give each client its own address, so a blocklist entry or a traffic spike aimed at one client does not land on the others.
- Software that binds to an address. Some licensing and some older applications tie themselves to a specific IP, and it is easier to give them one than to argue with them.
One use we would steer you away from: running a mail server on these addresses. We do not offer custom reverse DNS at the moment, and outgoing mail without a matching reverse DNS record struggles to reach inboxes. Send mail through a provider built for it.
Pick a size for next year, not next week
Moving to a bigger block later usually means new addresses, and new addresses mean updating DNS records, firewall rules and anything else that knows the old ones. It is cheaper to count once, generously:
- List every service or guest that needs its own public address today.
- Add what you expect to need in the next twelve months.
- Pick the smallest block that covers both, with a couple spare for testing and migrations.
Two worked examples. A web agency hosting a handful of clients on the €209 entry server with a /28 pays €235 a month and has 13 addresses to hand out. A Proxmox host on the dual Xeon E5 2699 v4 at 1 Gbps with a /27 pays €357 a month for 44 cores, 256 GB of RAM and 29 public addresses for its guests.
When a VPS is the cheaper way to get addresses
If what you really need is a few small machines with their own addresses, rather than one big machine with many, compare against our KVM VPS plans. Every VPS includes one IPv4 address, extras cost €1.50 a month each with up to ten per VPS, and a VPS I KVM costs €4 a month in Bucharest. Five tiny services on five separate VPS can cost less than a dedicated server with a /29, and each one fails on its own.
Bringing your own addresses
If you already hold your own /24, with or without your own ASN, open a ticket before you order and tell us what you have. Whether we can route a block depends on the block and on the location, so we confirm it case by case rather than promise it here.
Ordering the addresses
- Choose a server on the dedicated servers page. If you are still deciding on a port speed, our guide to the €209 entry server and the 10 Gbps cost breakdown cover both ends of the range.
- In the subnet step, pick the /29, /28 or /27.
- Check out. Once the server is delivered, its addresses are listed with it in the client area.
