Ten honest explainers on how datacenter IPs work, how to choose and check them, and how to size a list. Every guide states its sources.

**Quick answer — What do the RackProxies datacenter proxy guides cover?**

The **RackProxies** datacenter proxy guides explain, in 10 short articles, what a datacenter IP is, how to pick its city, check it, read its geolocation, size a list and choose between IPv4 and IPv6 or SOCKS5 and HTTP. The docs cover setup and code. RackProxies rents dedicated IPv4 from $1.29 per IP for 30 days. No KYC, crypto only.

## Which guide answers my question?

Start with the basics, then pick the guide for your decision.

- **[What is a datacenter proxy?](https://rackproxies.com/guides/what-is-a-datacenter-proxy/)** — Routing, ASNs and hosting labels, static vs rotating, dedicated vs shared, and when a datacenter IP is the right tool.
- **[How to choose a datacenter city](https://rackproxies.com/guides/choose-a-datacenter-city/)** — Find where a site is hosted with DNS, RDAP and traceroute, then compare cities with the 200 km per ms rule.
- **[Datacenter IP check](https://rackproxies.com/guides/check-a-datacenter-ip/)** — Four keyless lookups and a Python script: RDAP holder, announcing ASN, PeeringDB type and reverse DNS.
- **[Why a proxy shows a different country](https://rackproxies.com/guides/datacenter-ip-geolocation/)** — How geolocation databases work, RFC 8805 geofeeds, and what to do when the city is wrong.
- **[IPv6 vs IPv4 proxies](https://rackproxies.com/guides/ipv6-vs-ipv4-proxies/)** — IPv4 exhaustion since 2011, the 2^64 addresses of a /64, why sites count IPv6 by block, and dated prices.
- **[How many proxies do I need?](https://rackproxies.com/guides/how-many-proxies-do-i-need/)** — Three counts (locations, spares, connections) and worked examples matched to plan sizes.
- **[/24 subnet diversity](https://rackproxies.com/guides/subnet-diversity/)** — What a /24 is, why some sites count per subnet, and a Python script that groups your list.
- **[SOCKS5 vs HTTP proxy](https://rackproxies.com/guides/socks5-vs-http-proxies/)** — RFC 1928 against HTTP CONNECT, socks5 vs socks5h DNS, logins byte by byte, and UDP.
- **[Datacenter proxy bandwidth](https://rackproxies.com/guides/datacenter-proxy-bandwidth/)** — What "unlimited" means on nine providers' pages as of 19 October 2026, and the questions to ask.
- **[Rotating vs static datacenter proxies](https://rackproxies.com/guides/rotating-vs-static-datacenter-proxies/)** — Provider rotation against rotating your own list in code, with a round-robin example.

## Where are the setup docs?

- **[Quickstart](https://rackproxies.com/docs/quickstart/)** — Buy, find your IPs, test HTTP and SOCKS5 with curl, set the allowlist, fix common errors.
- **[Connection format](https://rackproxies.com/docs/connection-format/)** — The IP:PORT:USERNAME:PASSWORD line, URL form, password encoding, TXT and CSV exports.
- **[Code examples](https://rackproxies.com/docs/code-examples/)** — curl, Python requests and aiohttp, Node.js undici and proxy agents, Playwright.

## How are these guides written?

Each guide answers one question in its first paragraph, then explains the mechanism with public sources. Numbers come from standards (RFCs), registries (IANA, RIPE NCC and the other regional registries), PeeringDB or provider pages read on a stated date. Where a number would be a guess, we leave it out: we do not publish speed figures, success rates or pool sizes.

We also say what datacenter proxies cannot do. A datacenter IP is labelled "hosting" by IP databases because it is hosted; no guide here suggests otherwise. Uses stay within our [acceptable use policy](https://rackproxies.com/acceptable-use/): public-data collection, price and stock monitoring, SEO tracking, ad and localization checks, monitoring and QA of your own services, and allowlisted access to partner systems.

## Where do I go after the guides?

When you know what you need, compare plans on [pricing](https://rackproxies.com/pricing/): 1 IP costs $1.29, 10 IPs cost $12.69 and 100 IPs cost $59.25 ($0.59/IP). Pick a location among 22 [countries](https://rackproxies.com/countries/) and 34 [datacenter cities](https://rackproxies.com/cities/), or read the [datacenter proxy product page](https://rackproxies.com/datacenter-proxies/). Terms are defined in the [glossary](https://rackproxies.com/glossary/).

## Questions about the guides

### Where should a beginner start?

Start with [what is a datacenter proxy](https://rackproxies.com/guides/what-is-a-datacenter-proxy/), then [how many proxies do I need](https://rackproxies.com/guides/how-many-proxies-do-i-need/) and the [quickstart](https://rackproxies.com/docs/quickstart/). Those three cover what you are buying, how much of it, and how to test it with one curl command. The other guides answer narrower questions when they come up.

### Are the code samples safe to run?

They only call public test endpoints (api.ipify.org, httpbin.org/ip, example.com) or public registries (rdap.org, RIPEstat, PeeringDB), and they use documentation addresses as placeholders. Each Python sample passes `python -m py_compile` and each JavaScript sample passes `node --check`. Replace the placeholders with your own lines before running them.

### How often are the guides updated?

When a fact changes: a standard, a registry figure or a provider's public page. Each guide shows its update date at the top, and dated competitor facts state the day we read the page, 19 October 2026 for this edition. Prices of our own plans always come from the live price list.

### Do the guides compare RackProxies with other providers?

Some do, with named providers, prices, dates and links, never with ratings. The bandwidth and IPv6 guides quote provider pages read on 19 October 2026. For full price comparisons, see the [price index](https://rackproxies.com/data/datacenter-proxy-price-index-2026/) and the [best datacenter proxies of 2026](https://rackproxies.com/best/datacenter-proxies-2026/).

### Can I buy datacenter proxies without ID?

Yes. No KYC: no ID, no selfie, no documents to sign up, top up or buy. You pay in BTC, USDT, USDC, ETH, SOL, LTC and log in with an account number; an email is optional. This suits buyers who prefer not to upload identity documents. See [no-KYC proxies](https://rackproxies.com/no-kyc/) for what we keep.
