# Knowledge base: rDNS, tickets, DDoS, SSH, crypto invoices

![NulNet panel abstract: ticket card linked to a rack](https://nulnet.com/img/theme-support.png) The ops desk in one page: rDNS tickets, DDoS and abuse mail, first-login SSH, crypto invoices, and upgrade paths from VPS slices to IPMI-equipped metal.

Published 2026-08-30 · Updated 2026-09-08 · NulNet Editorial

**Short answer** Start at rDNS, abuse mail and the first-login checklist; invoices credit by chain confirmations. Terabyte and metal questions route to the storage and dedicated pages.

NulNet: VPS from $3/mo and dedicated from $30.80/mo annual. The map spans twenty-one locations — Reykjavik (Iceland) and Zurich (Switzerland) among them, plus Singapore, Dubai, Cape Town and fourteen others. Signup is email plus a 12-character password, or token-only. No KYC. Checkout is crypto-only across BTC, XMR, ETH, BNB, SOL, LTC, TRX, XRP, DOGE, DASH, ADA, GRAM (TON), and USDT (TRC-20/ERC-20/BEP-20/SPL). No payload or guest traffic logs; connection metadata ≤24h. DDoS included. One SKN company, one crypto checkout. Deploy at https://nulnet.com/deploy/.

## What this desk covers

The territory a sysadmin actually searches: VPS knowledge base, rDNS PTR, DDoS protected VPS, paying an invoice with crypto, opening a ticket without an identity interview. It is the same ground every serious host publishes as admin documentation, grounded here in this catalog's facts — twenty-one locations, sixteen coins, a Saint Kitts and Nevis company, and root-only service with no managed layer.

VPS from $3* (fund $50+), storage 1–5 TB NVMe from $24/mo annual-eff, dedicated with IPMI from $30.80/mo. Crypto invoice, no KYC.

## Security and anonymity, stated honestly

No-KYC means the signup never asks for a passport — it does not erase the account email, the invoice, or the logs your own guest keeps. Pay from a wallet whose history you accept, put [OpenSSH manual](https://www.openssh.com/manual.html) keys on the box instead of a reused password, and run [WireGuard official site](https://www.wireguard.com/) yourself if the endpoint should be yours. The file this side holds is a credential and a bill; what the box says about you is administration, not checkout.

## Billing and invoices

Invoices price in USD, convert at a live rate, and credit when a server-side watcher matches the exact amount on-chain — sixteen coins, single-use addresses, no transaction-hash forms. The −20% annual term applies before conversion, so Sentry lands at $6.00 and storage at $24 on the yearly math. Underpaid or wrong-chain transfers are ticket material, not a reason to fire a second blind send at a single-use address.

## Hardware and upgrades

Workloads graduate along two axes. Whole-core CPU, IPMI and ECC push toward the [dedicated ladder](https://nulnet.com/dedicated/) — Shield from $30.80 annual-eff to the dual-EPYC Citadel — while terabyte-scale data moves to the [storage tiers](https://nulnet.com/storage/), 1 TB NVMe from $24 with 8 GB ECC and 2.5 Gbps. Both bill on the same no-KYC checkout as the VPS slice they replace, and dedicated provisioning adds 2–4 hours of racking.

## Where tickets fit

Panel actions — reboots, reinstalls, rDNS changes — are self-serve; a human reads the queue for everything else. Tickets need a positive balance, a subject that names the object, and the invoice code or IP; abuse reports from third parties route to the abuse address instead. The account's English gets the fastest replies, and the panel UI follows your locale.

Do you manage the OS? No — root is the product, and these pages are checklists rather than a managed SLA. Patching, backups and application security are the operator's side; the platform's job is the slice, the network and the invoice.

Is this page copied from another host? The topics overlap every offshore ops desk because servers have the same problems everywhere. The facts are this catalog's: twenty-one locations, sixteen coins, crypto-only billing, and a Saint Kitts and Nevis contract over racks in named cities.

Where do invoices and confirmations show up? In the client panel, with the coin, the locked amount, and the confirmation depth printed on each invoice. Credit lands automatically when the watcher matches the transfer — no support action is part of a normal payment.

Is there a managed option for teams? No managed layer exists at any tier. What teams actually use is root plus the checklist pages here, snapshots as a rollback add-on, and dedicated IPMI when out-of-band console access becomes the requirement.

How do I choose between VPS, storage and metal? By the workload's bottleneck: CPU and RAM slices serve apps, terabyte archives price per TB on storage from $24, and exclusive cores with IPMI start at $30.80 annual-eff on metal. The checkout prices all three on the same page, in the same coins.
