Latest insights, guides, and updates from our team
GDPR rewired the WHOIS protocol overnight in 2018 and the registrar industry has been negotiating with itself about how to comply ever since. We walk through what fields actually got redacted, which ones never were, where the disclosures still happen (ccTLDs, RDAP, court orders), and show before/after lookups on real domains.
Four metrics that every gamer cares about and almost nobody defines correctly. We pin down what each one actually measures, show how they compound in a real game session, and embed a live measurement widget that pings a target from your browser and reports min/avg/max latency, jitter, and packet loss.
Most ISP throttling isn't a blunt speed cap — it's a per-host quality-of-service degradation that only shows up on Netflix, YouTube, or a single videoconferencing vendor. We explain how to test for it from inside your own browser by comparing throughput across several known targets and reading the difference.
Whether you need your local IP for setting up devices or your public IP for troubleshooting, here is exactly where to look on Windows 11, Windows 10, macOS, Linux, iPhone, and Android — plus what your IP actually reveals about you.
DNSSEC adds cryptographic signatures to the global DNS so resolvers can prove the answers they get back are real. Here is how the chain of trust works, who actually validates it, and an in-browser checker that tests your own resolver right now.
Border Gateway Protocol routes every packet on the internet — and it operates almost entirely on trust. We trace the AS-paths of the most consequential hijacks of the past 15 years and explain what RPKI, ROAs, and route leak protection actually do.
All three of them hide your IP — but they protect (and don't protect) very different things. Walk through your threat model with our decision tree and a side-by-side comparison so you stop using the wrong tool for your job.
JA3 and its successor JA4 turn the contents of a TLS ClientHello into a short hash that uniquely identifies the client library — Chrome vs Firefox vs curl vs a custom Go bot — before a single byte of HTTP is exchanged. Here is how to read the hash, how to use it for fraud detection, and how attackers evade it.
Chromium is slowly freezing the User-Agent string and shifting browser identity into a set of opt-in Sec-CH-UA headers. We show you the new headers, what each one reveals, and how trackers are adapting — paired with a live panel that prints what your browser sends right now.
Internationalised Domain Names let you register addresses in any script — and let attackers swap Latin letters for visually identical Cyrillic or Greek ones. We walk through how punycode encoding works, where browsers draw the line, and embed a live converter that flags confusables in any URL you paste in.
The concept of Typo Density measures how many of these typo variations of a given domain are registered. A high typo density indicates significant public interest in the site – and potentially higher cybersquatting or phishing risks.
Geolocation accuracy is the precision with which an IP address can be mapped to a specific geographic location. This article discusses the factors affecting geolocation accuracy and provides a method to estimate it.
Browser fingerprinting is a technique used to identify and track users by analyzing their browser environment. This article discusses the various methods used to fingerprint browsers and provides a method to estimate it.
