About CGNAT.wtf

CGNAT.wtf answers one question for people who want to run things at home: will my internet provider let the internet reach me? For each ISP it tracks whether CGNAT is the default, how to get a public or static IP and what that costs, IPv6 support, and what the terms say about running servers.

How the data works

• Every fact links to a source, labeled official (the ISP's own page), official-forum (ISP staff on its forum), community (customer reports) or secondary.
• If we can't source something, it says Unknown. We don't guess.
• Each ISP shows a last-verified date. Policies vary by area and change over time, so check the linked source.
• Corrections come in through reports and are reviewed by hand.

Scope

This site covers ISP facts only. It doesn't review, rank, recommend or compare VPN, tunneling, remote-access or networking products, and it doesn't take sponsorship from those companies.

Independence

CGNAT.wtf is an independent project. It isn't affiliated with, endorsed by or funded by any ISP or any VPN, tunneling or networking company, and it doesn't take sponsorship from VPN, tunnel or remote-access vendors. It covers ISP facts only.

Privacy

• No ads and no tracking cookies. We use Cloudflare Web Analytics to count page views. It's cookie-free and doesn't track individual visitors.
• The forms use Cloudflare Turnstile to block spam bots. It loads only once you start filling in a form.
• Reports store what you type, your browser's user agent and a salted, one-way hash of your IP address to catch abuse. We never store the raw IP address. ZIP codes are cut to the first three digits.
• The newsletter stores only your email address. To be removed, email hello [at] cgnat [dot] wtf.
• The checker looks up your public IP from your browser using the public echo service named on that page. CGNAT.wtf doesn't store it.
