Check if your internet connection in Indonesia is being filtered. Detect DNS-based blocking used by Indonesian ISPs.

Running check

Probing 5sites from your connection and cross-checking each against indiwtf.com's block list.

How it works

The check inspects your DNS resolution and compares it to trusted servers. Three signals tell us if you're being filtered.

DNS lookup

Checks if your DNS queries are being redirected or blocked by your ISP's DNS servers.

Block detection

Identifies if websites are returning block pages or fake IP addresses instead of real servers.

ISP filtering

Compares results from your ISP against trusted international DNS servers to spot manipulation.

Why DNS blocking happens

Behind the scenes of internet censorship in Indonesia.

Government mandate

Indonesian ISPs are required by Komdigi (formerly Kominfo) to block access to certain websites. The most common method is DNS blocking, where your ISP's DNS server returns incorrect IP addresses or redirects you to a block page.

How it's implemented

When you try to access a blocked site, your ISP's DNS either returns a fake IP that shows a “site is blocked” message, or fails to resolve the domain entirely. This tool checks if your DNS queries are being manipulated.

How to bypass it

If you're being filtered, here are the practical options.

Cloudflare WARP

Mullvad VPN

Privacy-focused VPN service with no logging policy.

Tor Browser

Anonymous browsing with built-in censorship circumvention.

Custom DNS

Switch your DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8).
