Webcas.tr is a simple tool that ensures you can always reach websites by fixing broken or tampered DNS replies on your device. No VPN needed, just install and browse freely.
Having trouble reaching a website? Test it below to see if it's a DNS issue that Webcas.tr can fix
Good news! This domain appears to be accessible from your network. However, Webcas.tr can still help with:
This domain appears to be inaccessible or experiencing DNS issues. Webcas.tr can likely help you access this website by:
Webcas.tr is designed specifically to solve these types of DNS issues.
If any of these sound familiar, Webcas.tr can help
You try to visit a website and get "domain not found" errors, even though you know the site exists.
Webcas.tr detects these DNS failures and automatically uses secure alternative methods to find the correct website address.
You can't reach your API, or your Server backend in general.
Webcas.tr can also detect and fix machine-to-machine communication, so the tools on your server or personal computer will work flawlessy around DNS blockages.
Your internet provider or network blocks access to certain websites through DNS manipulation.
Webcas.tr bypasses DNS-based blocks by using encrypted DNS queries that can't be easily intercepted or manipulated.
You have set up a VPN, for example, OpenVPN, but it doesn't resolve your hostname.
Hostnames that cannot be resolved are a simple DNS resolution issue that Webcas.tr is likely to fix.
You type in one website address but get redirected to a different site or search page.
Webcas.tr detects suspicious redirections and ensures you reach the actual website you intended to visit.
Websites take forever to start loading because of slow DNS lookups from your provider.
Webcas.tr caches correct DNS responses locally, making subsequent visits to websites much faster.
Simple, powerful, and works right out of the box
Access websites, APIs, Tools without DNS-based restrictions. Webcas.tr helps you bypass local DNS censorship so you can browse the internet as intended.
No manual configuration needed. Webcas.tr automatically detects DNS failures or tampering and fixes them on the fly without you having to do anything.
Uses encrypted DNS (DoH) so your website lookups can't be spied on or corrupted. What is DoH?
Won't slow down your internet – it only kicks in when needed, and caches good results for next time, actually improving speed!
Works in the background on Windows and Linux. Set it once and enjoy the internet without DNS errors.
Webcas.tr doesn't log your DNS queries or browsing habits. Your privacy is respected and protected at all times.
A simple solution to a complex problem
Webcas.tr runs quietly on your computer as a DNS middleman – when your normal DNS fails or gives incorrect answers, it automatically asks a secure global DNS and fixes the answer.
Your browser needs to look up the website's address (like finding a phone number in a phonebook).
Instead of your computer asking your ISP's DNS server directly, Webcas.tr catches the question first.
Webcas.tr asks a trusted DNS server for the website address, bypassing potential issues with your default DNS.
If there's any problem, Webcas.tr automatically switches to an encrypted connection (DoH) to get the correct address.
The correct website address is returned to your browser, and you connect to the site without ever noticing the work done behind the scenes.

Webcas.tr is not a VPN. It will not work if websites are blocked by IP address, and it does not encrypt your network traffic. It's a DNS solution only, which is sufficient for most DNS-related issues.
Webcas.tr is a simple tool that makes sure your computer can always find the correct addresses for websites. It works in the background to fix DNS problems that might prevent you from accessing certain sites.
DNS is like the phonebook of the internet. When you type a website name (like google.com), DNS converts it to the actual address where that website is located. If this process fails or is tampered with, you can't reach the website. Webcas.tr ensures this process works correctly.
No, Webcas.tr handles that for you automatically. Just install it and it takes care of everything in the background.
No, it only fixes how your computer finds websites (DNS). It's much lighter than a VPN and only focuses on making sure you get the right IP addresses. Your other traffic stays direct and is not encrypted.
Webcas.tr actually can make it faster in many cases, thanks to caching. It only does extra work if it detects a problem. Otherwise, it simply passes along the answer quickly.
Webcas.tr is free for personal use but is rate-limited. High-rate usage and commercial applications require requesting a quote from contact@tangelo.com.tr.
Currently, Webcas.tr is available for Windows and Linux operating systems only.
No. Webcas.tr doesn't collect your DNS queries – unresolved querys are sent to our API to be resolved by a public DNS Server like Google or Cloudflare, but these requests are not analyzed or logged in any way, it's a pass-through system.
Want to peek under the hood? Here's how Webcas.tr works at a technical level
Webcas.tr uses DNS-over-HTTPS as a fallback mechanism. Unlike regular DNS queries which are sent in plaintext over UDP, DoH encrypts DNS queries by using the HTTPS protocol, preventing them from being read or modified in transit.
This is particularly useful for bypassing DNS-based censorship, as the encrypted nature of HTTPS makes it difficult for intermediaries to determine what DNS queries are being made.
Webcas.tr sets your system DNS to 127.0.0.1, acting as a local DNS resolver. All DNS queries are first handled locally before being forwarded to upstream resolvers.
This approach allows Webcas.tr to intercept, analyze, and potentially modify DNS responses without requiring changes to applications or browsers.
For improved performance, Webcas.tr updates your local hosts file with verified domain-to-IP mappings. This ensures that future queries for the same domain will be served locally with the correct IP, bypassing potentially poisoned DNS caches.
The hosts file is a system file that maps hostnames to IP addresses, and is checked before any DNS queries are made.
While Webcas.tr defaults to using Google's DNS servers (8.8.8.8), the upstream DNS resolver is fully configurable. Advanced users can specify their preferred DNS servers for primary resolution.
This flexibility allows for customization based on specific needs, such as privacy-focused DNS providers or region-specific optimizations.
Webcas.tr implements sophisticated error detection to identify DNS poisoning, NXDOMAIN hijacking, and other forms of DNS tampering. When suspicious responses are detected, it automatically switches to secure fallback mechanisms.
The fallback system uses a combination of alternative DNS providers and DoH to ensure reliable resolution even under adverse network conditions.
Webcas.tr runs as a system service with appropriate permissions to modify DNS settings and the hosts file. It carefully preserves original system settings and restores them when exiting.
Detailed logging options are available for troubleshooting, with transaction IDs, query timings, and error states captured for diagnostic purposes.
