Acrylic is a local DNS proxy for Windows which improves the performance of your computer by caching the responses coming from your DNS servers and helps you fight unwanted ads through the use of a custom HOSTS file (optimized for handling hundreds of thousands of domain names) with support for wildcards and regular expressions.

When you browse a web page a portion of the loading time is dedicated to name resolution while the rest is dedicated to the transfer of the web page contents. What Acrylic does is to reduce the time dedicated to name resolution for frequently visited addresses closest to zero possible. Furthermore Acrylic's sliding expiration caching mechanism and DNS silent updates are able to improve the browsing experience independently of the browser.

With Acrylic you can also gracefully overcome downtimes of your DNS servers without disrupting your work, because in that case you will at least be able to connect to your favourite websites and to your email server.

  • Is there no way of setting up DNS aliases? I created an entry " yahoo". Then when I "ping", I successfully get a reply from localhost, but when I "ping yahoo", I get nothing.

  • So Why does virustotal come up with 3 antivirus programs that say it contains a trogan downloader?

  • After a few hours of debugging, I'm still stuck trying make it work.. Both, Acrylic Service and Console, doesn't receive any response from DNS server (I've tried google DNS, OpenDNS, my ISP DNS and Level3 DNS), as viewed in debug log and Sysinternals Procmon. Acrylic receive queries from client, forward to DNS server, but receive nothing in response.. I've noticed that source port of Acrylic queries is 53, the same usual listening port of a DNS server.. Maybe the DNS servers had refused such source port, as part of some DDOS protection (suspicious source port). Or maybe Acrylic queries are malformed.. In fact, none udp packet is received from DNS server after each Acrylic sent packet (to DNS) I've tested only locally, with last version of Acrylic, and default settings in HOSTS file and Configuration file, on a Windows 7 64 bits machine. It's just me ? Anyone else had such problem ?

  • Good Software, but at the moment you need manual backup before you update to a new version or your Configuration and hosts files are lost, overwritten by the installer.
