I happened today, doppo have revived my Mac OS X 10.5.8
Using both Safari and FireFox didn’t open some sites like Google or Apple, while Bing. Surfing the internet was slow and it took a lot to open web pages. DNS problems, but it seemed as if he had set already 220.127.116.11
the problem is caused by using IPv6
I solved after three hours in this manner:
In System Preferences -> network -> airport -> advanced -> TCP / IP
In IPv6 configuration: off
Now my Mac OS X 10.5.8 browse at all sites, especially conked with Google, with Apple’s official website and some other sites. The problem seemed to be due to the DNS, I tried to see if it was the airport, I reinstalled Flash player v 10 to 10.5.8.
Finally I succeeded …
