Well you need to verify it is a DNS issue. Can you get to Google using the above IP address?

Either way the DNS workaround is merely overriding DHCP-supplied DNS IPs with either your ISP DNS, or public DNS IPs like these:
208.67.222.222
208.67.220.220

In my case, and others I have read about, the DNS IP supplied by the router via DHCP was the router's IP (i.e., it will match gateway IP). While this should work, in some cases it doesn't work right with the iPhone, hence the DNS override workaround.

But again, I wouldn't try that without first testing Google via IP.
