All traffic to/from some IP addresses is blocked, additionally all Chinese DNS servers respond with random A records when the domain name is banned, for example:
$ host facebook.com 202.97.0.6
facebook.com A 8.7.198.45
$ host facebook.com 202.97.0.6
facebook.com A 243.185.187.39
$ host facebook.com 202.97.0.6
facebook.com A 243.185.187.39
$ host facebook.com 202.97.0.6
facebook.com A 46.82.174.68
$ host facebook.com 202.97.0.6
facebook.com A 59.24.3.173
(202.97.0.6 is an open resolver in China)
- phonon 9y agoSo you can get around the block if you use 8.8.8.8 for DNS?
- ospider 9y agoNo you can't, you will still get a connection reset error
