InstantIPCheck vs Whoer.net
Whoer.net is a long-running anonymity checker with a disguise score, proxy flags and browser details. InstantIPCheck is a full IP toolbox: live IPv4/IPv6, leak tests, speed, Whois and lookup, without a signup wall.
Where Whoer.net is strong
Whoer.net focuses on “how anonymous do I look?” It surfaces IP, ISP, hostname, OS, browser, proxy/anonymizer hints and a disguise-style score. That is useful as a quick privacy snapshot.
Where InstantIPCheck goes further
InstantIPCheck still shows IP, location, ISP and ASN, then adds DNS leak tests, WebRTC, connectivity, speed, MTR, Whois, MAC lookup and a downloadable diagnostic report. The homepage is a readable report sheet rather than a dense scorecard.
