I use unblock-us to access services that have this really stupid idea of IP-based positioning (hey guys, my IP does not mean anything!). This service (like many others) proxies your DNS traffic through their own servers so you can pretend to be anywhere on the planet. You only have to add their DNS-servers to your computers network settings or to your WIFI-router so all your devices can use it without changing their configuration.
Unfortunately, the chromecast has it's own google DNS configured and those google assholes don't let you change it or disable the feature. In the linked support thread, you can see how you can spoof the DNS traffic using
iptables in your router, so the chromecast will actually talk to unblock-us instead.
My WIFI router is an oldish Apple Timecapsule and those things are quite
Luckily, I have an old iMac standing around, that I now use to spoof the DNS traffic that wants to talk to googles servers:
- connect your computer via network cable, so you can share the WIFI
- enable internet sharing in
System Preferences > Sharing > Internet Sharing > Wi-Fi
- connect your Chromecast to your new WIFI
- make a small change to your macs routing table
sudo route add 22.214.171.124 126.96.36.199 # add host 188.8.131.52: gateway 184.108.40.206 sudo route add 220.127.116.11 18.104.22.168 # add host 22.214.171.124: gateway 126.96.36.199
After this change, all access to googles DNS servers with the IPs
188.8.131.52 will go to a DNS server of unblock-us (
If you to access a service that relies on IP based location like netflix.com, you should be pleased to see that it works as expected.
