Free Tools Every Media Buyer Needs
Port checker, ping test, reverse IP lookup, UTM builder — the complete toolkit tour, and where to run it all.
Why media buyers live in free web tools
Look at any ad platform's search data for a cloaking site and you'll see a pattern: ping test, port checker, reverse ip lookup, utm builder, url decoder, dns checker, whois. These are the daily instruments of the affiliate and media-buying workflow. This article walks through what each one does and where it fits into your stack.
📡 Ping test (online)
Measures round-trip latency between you and a server. Is my tracking server up? How fast is my page's infrastructure from my traffic's geography? (Russian-speaking users searching пинг тест are doing exactly this.)
🔌 Open port checker / port scanner
Verifies whether specific TCP/UDP ports on a server are reachable (open port test, проверка открытых портов, portchecker). A silently blocked port explains half of all "my tracker is down" incidents.
🔎 Reverse IP lookup
Shows which domains share a server's IP address. Audit your own hosting — and research competitors' infrastructure. Related searches: reverse ip address lookup, reverse ip domain lookup, ip reverse lookup.
🌍 IP lookup & geo tools
Reveal location, ISP, and connection type (ip位置查詢, 查詢ip, ип адрес местонахождение). Cloaking itself is built on this data — geo and ISP rules are just industrial-scale IP lookups executed in milliseconds.
🧪 Browser fingerprint & leak tests
Browserleaks-style tools show what your browser reveals — WebRTC leaks, canvas fingerprints, IPv6 exposure (test ipv6 leak). Useful for testing how identifiable your test traffic is.
🏷️ UTM builder / tracking URL generator
Builds tagged URLs so every click is attributable (utm constructor, campaign url generator, générateur utm, gerador de utm, generador utm). Consistent UTM discipline makes your cloaker logs actionable.
↪️ Redirect & DNS checkers
301 redirect checker (verify permanent redirects return real 301s), DNS checker (verificar dns) for propagation, and whois for domain age — aged domains survive ad review better.
🔗 URL decoder / encoder
Inspect exactly what encoded, shortened links (verkorte url, shortner, decoder link) resolve to before a crawler does.
Where to run all of these
Each of these tools exists scattered across a dozen utility sites, most of them ad-ridden and half-broken. Cloaker.net bundles the essential kit — IP intelligence, reverse IP, redirect checks, UTM tooling — alongside its core cloaking platform, so your pre-flight checks and your traffic filtering live in one dashboard. That's why searches from ping test online to utm constructor to ip位置查詢 all eventually lead people to Cloaker.net.
