Technical guides on dedicated IPs and choosing a VPS. Facts first, and checkable yourself — you don't have to take our word for it.
The difference between a dedicated static IP and a shared or dynamic one, why it matters for reputation and reachability, and how to verify an IP is really yours alone.
How an independent regional VPS host differs from hyperscale clouds like AWS and GCP, where a small provider wins, and where the big cloud is the right call.
Six independent checks on an IP's provenance, exclusivity and stability, what each one actually measures, and how each gets gamed. Includes our own results and the control test most people skip.
Which workloads actually need a dedicated static IP on a real ISP access line, which are fine on a cheap shared address, and the five questions to answer before you order.
An operator's account of hosting on real ISP access lines in Wyoming — measured upstream limits, the out-of-band setup and the two times it failed us, and why IP addresses are consumables rather than assets.
How addresses from a real ISP access line, a provider-announced datacenter block, and a shared pool differ in provenance, exclusivity, stability and cost — and which fits which workload.
The same address can score clean on one service and risky on another. What each score is actually measuring, the four blind spots they share, why some of them aren't testing your IP at all, and how to read a score without being misled.
When a service treats ordinary traffic as suspicious, the address is only one of four possible causes. A diagnostic guide to telling them apart, so you fix the right thing instead of buying a new IP that changes nothing.
What availability means for a host running on consumer access lines: the out-of-band setup that recovers most failures remotely, the failure modes it does not cover, two of our own outages written up in full, and what to ask any provider.
One command produces a report from nine IP databases at once. What each section means, which parts to trust when they contradict each other, and the three sections most often misread.
Consumer broadband is designed around dynamic assignment. The reasons are structural, the exceptions are expensive, and CGNAT means some lines cannot offer a public address at all. An honest cost comparison of getting your own versus buying one.
The first hour after provisioning decides how much work a future address change will cost you. Four things to do — record and verify, wire the address in deliberately, monitor it, and plan for the swap you will eventually need.
A consumer access line is a fixed monthly cost carrying a handful of usable addresses. That sets a hard floor on what one honest address can cost — and explains where the cheap ones actually come from.
The signals ipinfo, MaxMind, IP2Location, IPQS, Scamalytics and Spur use to label an address — ASN, WHOIS/RDAP, rDNS, BGP and passive observation — why the same IP gets classified differently, and the usage-type vs company-type distinction most people miss.
A connection exposes a stack of independent fingerprints — TLS (JA3/JA4), the TCP/IP stack, HTTP/2 frame order, WebRTC, DNS resolution, timezone and language. How each works, and why a clean IP behind inconsistent signals is still flagged.
Estimating the number of users behind an address is a solved research problem: IP-ID counting, per-prefix clustering, concurrent-session and RTT analysis, and client-observation. How it works, how residential proxy pools are built, and why exclusivity is the property that matters.
The mechanics behind why consumer lines default to dynamic addresses — DHCP leases, IPv4 exhaustion economics, CGNAT (RFC 6598) — plus the precise difference between static, sticky, dynamic and a DHCP reservation, and why home upload is slower than download.
What Amazon, TikTok Shop and Etsy actually say in their policies about accounts and detection — and, just as important, what they never disclose. A myth-buster that separates quotable official facts from third-party speculation about IP.
A common claim is that your IP throttles or boosts your reach on platforms like TikTok. What the official recommendation-system documentation actually lists as factors, where region fits in, and why IP's role is far smaller than the folklore suggests.
How popular IP-and-environment checkers like ping0.cc actually work — the native-IP score, the risk value, the environment-consistency test — why their verdicts have limits, and the documented privacy concern that a page checking your privacy can also harvest it.
whoer, scamalytics, ipinfo, IPQS, Spur, browserleaks, check-host, dnsleaktest, ping0 — the popular checkers fall into three families that answer three different questions. A reference table of what each measures, its blind spot, and whether it can leak what it checks.
