Romania VPS IP Addresses: Dedicated IPv4, /64 IPv6 and What to Check Before You Pay

Every IronBalkans plan — from Iron 1 at €3.99/mo to Iron 4 at €29.99/mo — includes one dedicated IPv4 address and a routed /64 IPv6 block, with no separate per-IP fee. That matters more than it sounds, because a large share of cheap "VPS" offers on the market give you a shared IPv4 behind NAT, charge extra for a real one, or hand you an address with a history you didn't ask for.

Before you pay for any server, there are four things worth checking about its IP addresses: whether the IPv4 is genuinely dedicated, whether you get usable IPv6, what the address's reputation looks like, and whether you can set reverse DNS. Here's how to check each one, and what to do if an answer comes back wrong.

The direct answer: what you need from a VPS IP

A VPS IP setup is adequate for most projects if it gives you:

• One dedicated IPv4, bound to your server, with all ports available to you — not a shared address with an allocated port range.
• A routed IPv6 block (a /64 is the standard allocation) so you can assign addresses to containers and services instead of multiplexing everything onto one address.
• Control over reverse DNS (PTR), or at least the ability to request it, if you ever want to send email.
• A clean-enough reputation that you aren't inheriting someone else's spam or abuse history.

IronBalkans includes the first two on every plan and runs DDoS filtering on all of them. The reputation part is something you should verify yourself on any provider, including this one — I'll show you how below.

Dedicated IPv4 vs. NAT: the difference that breaks projects

A dedicated IPv4 means the address belongs to your VPS alone. You can bind any service to any port, terminate TLS on 443, run a VPN on 51820, and your firewall rules behave the way the documentation says they will.

A NAT VPS shares one public IPv4 across many customers and assigns each one a slice of ports — you might get 20 ports in the 30000-range and a shared 80/443 via the provider's reverse proxy. These are cheap for a reason, and they quietly rule out a lot of work:

• You can't run standard-port services without the provider's proxy sitting in front of your traffic.
• You usually can't set reverse DNS, which kills outbound email.
• You share reputation with every neighbour on that address. One spammer and your HTTPS endpoint starts eating CAPTCHAs.
• Inbound VPN and peer-to-peer setups get awkward or impossible.

If a listing doesn't explicitly say "dedicated IPv4" or "1 IPv4 included," assume NAT and ask. This is one of the specific items on the checklist for vetting a no-KYC VPS provider before paying in crypto, and it's one of the easiest things for a vague product page to hide.

What a /64 IPv6 block actually gives you

A /64 is 18 quintillion addresses. In practice you'll use a handful, but having a routed block rather than a single IPv6 address is genuinely useful:

• One address per service or container. Each Docker container, each nginx vhost, each test environment can have its own IPv6 address instead of fighting over ports on a single IP.
• Separation of outbound traffic. You can source different jobs from different addresses inside your block, which keeps unrelated activities from sharing one identifier at the destination.
• Headroom for IPv6-only internal services reachable without burning your single IPv4 on them.

Two honest caveats. First, IPv6 is not a privacy feature — a /64 is as traceable to your provider's allocation as the IPv4 is, and addresses derived from it are just as loggable. Second, IPv6 needs firewalling of its own. A ruleset that only covers IPv4 leaves every IPv6 address in your block wide open, which is exactly the mistake the nftables baseline ruleset guide is written to prevent.

Also worth knowing: some third-party services, payment APIs and older networks still don't speak IPv6, so plan to keep IPv4 as the path for anything external you depend on.

How to check an IP's reputation — before and right after you buy

You usually can't see your IP until the server is deployed, so do this in the first hour and decide quickly whether to ask for a replacement.

DNS blocklist check. Reverse the octets of your IPv4 and query a blocklist zone. For 203.0.113.45:

dig +short 45.113.0.203.zen.spamhaus.org
dig +short 45.113.0.203.bl.spamcop.net

An empty response is good. An answer in 127.0.0.x means the address is listed — the return code tells you which sublist. Spamhaus listings matter enormously for mail and barely at all for a web app.

HTTP reputation check. From your laptop, browse a few major sites through the server (a quick SSH SOCKS proxy works: ssh -D 1080 user@your-ip). If you get constant CAPTCHAs or outright blocks, the address has a history with the big anti-abuse databases.

Sanity checks. Confirm the geolocation resolves to Romania in the common IP databases — fresh allocations sometimes carry stale geo data, which affects nothing technically but can confuse services that geofence. Check that nothing is already listening on the address other than what you deployed.

If an address looks badly burned, say so to the provider early rather than building on it. On IronBalkans, that conversation happens over Telegram (@ironbalkansnews) or SimpleX, since there's no email on file by design — and that design is the point: account creation needs no name, email, phone or ID, just a generated account ID and a recovery key, and a paid server is live in under 60 seconds. If you want to see the current per-plan allocations, the plan and pricing breakdown covers what each tier includes and what other hosts commonly charge extra for.

Reverse DNS, PTR records and email

A PTR record maps your IP back to a hostname. Receiving mail servers check it, and a missing or generic PTR is one of the fastest ways to get your mail rejected outright. If you have any intention of sending email from the server — even just cron notifications — you need a provider that will set a PTR for you.

Getting a PTR is necessary but nowhere near sufficient. SPF, DKIM, DMARC alignment and the address's sending history all matter more, which is covered in detail in the guide to running a mail server on a VPS. The short version: if deliverability is business-critical, send through a relay and use your VPS IP for everything else.

What your IP address reveals about you

A dedicated IP is a convenience feature, not an anonymity feature. Treat it as a stable, public identifier:

• Anyone can see the IP, its geolocation (Bucharest, in this case), and the RIR/WHOIS record — which names the network holder, not you. No-KYC signup means there's no identity document tied to that allocation on the provider's side, but the address itself is still a single persistent dot that observers can connect across every service it touches.
• Reusing one IP for a personal blog, a VPN endpoint and a pseudonymous project links all three. If separation matters to your threat model, separate the servers, not just the ports.
• If you put a CDN in front of a site, the origin IP tends to leak through DNS history, Certificate Transparency logs, mail headers and internet-wide scanners. The guide on hiding a VPS origin IP behind a CDN walks through each leak path and the firewall-level fixes.

Common mistakes buyers make

Assuming "1 IP included" means dedicated. Some listings count a shared NAT address as included. Ask whether all 65,535 ports are yours.

Hard-coding the IP everywhere. If you ever migrate or get reassigned, IPs baked into configs, firewall allowlists on third-party services and monitoring endpoints all break at once. Use hostnames internally and keep an inventory.

Ignoring IPv6 until something breaks. An unfirewalled IPv6 stack is a real exposure, and a service listening on :: is reachable even when your IPv4 rules look tight.

Running mail on day one from an unverified IP. Check the blocklists first. Reputation recovery on a listed address is slow and often not worth the effort.

Forgetting DNS TTLs. If you expect an IP change, drop TTLs to 300 seconds a day ahead. Otherwise you're waiting out stale caches during a cutover.

Honest pros and cons

What a dedicated IPv4 plus /64 IPv6 gets you: full control of ports and TLS, PTR eligibility, clean separation of services, no reputation inherited from NAT neighbours, and room to grow into IPv6 without asking for anything extra.

What it doesn't get you: anonymity, immunity from blocklists, protection from your own misconfiguration, or guaranteed reputation. An IP's standing depends on what you do with it, and a persistent address makes your behaviour more trackable over time, not less. If your goal is to blend into a crowd rather than control your own endpoint, a shared commercial service fits better than a server with your own IP — the trade-offs are laid out in the comparison of a self-hosted VPN versus a commercial VPN service.

FAQ

Do all IronBalkans plans include the same IP allocation? Yes — one dedicated IPv4 and a /64 IPv6 block on every tier, from Iron 1 (1 vCPU, 1 GB RAM, €3.99/mo) up to Iron 4 (8 vCPU, 16 GB RAM, €29.99/mo). You're paying for CPU, RAM, NVMe and bandwidth as you move up, not for addresses.

Can I get additional IPv4 addresses? Each plan includes one. IPv4 is genuinely scarce globally, so if your project needs several addresses, ask before you buy rather than assuming — contact over Telegram or SimpleX.

Does my IP change when I reboot? A dedicated IPv4 stays with your server; it isn't drawn from a per-boot pool. Rebuilding or migrating to a new instance is a different situation, so plan DNS accordingly.

Is a dedicated IP enough to keep my project private? No. It gives you control of your endpoint, which is a prerequisite for good privacy practice, but the IP itself is public and persistent. Pair it with sensible separation between projects, a tight firewall, and minimal logging.

Will my IP be blacklisted because the host is no-KYC? Reputation attaches to addresses and ranges based on observed behaviour, not on a provider's signup policy. Check the blocklists for your specific address rather than judging by category.

Get started

If you want a Romania-hosted KVM VPS with a dedicated IPv4, a routed /64 IPv6 block and DDoS filtering included at every tier — paid in Monero, Bitcoin or Litecoin, with no email, name or ID at signup — compare the plans and deploy one. Run the blocklist and reputation checks above in your first hour on the box, before you build anything on top of the address.
