Weird DNS issues with Google.com on OSX

[canhaz]

Hey guys

I'm having this bizzarre issue I can't figure out.

Browsing to Google.com on FF or Chrome on OSX 10.7.3 produces:

The server at www.google.com can't be found, because the DNS lookup failed

If I do this on the console:

MacBook-Pro-2:~ $ ping google.com
PING google.com (74.125.224.66): 56 data bytes
64 bytes from 74.125.224.66: icmp_seq=0 ttl=52 time=39.865 ms
64 bytes from 74.125.224.66: icmp_seq=1 ttl=52 time=44.704 ms

And

MacBook-Pro-2:~$ nslookup www.google.com
Server: 192.168.1.1
Address: 192.168.1.1#53

Non-authoritative answer:
www.google.com canonical name = www.l.google.com.
Name: www.l.google.com
Address: 74.125.224.50
Name: www.l.google.com
Address: 74.125.224.49
Name: www.l.google.com
Address: 74.125.224.51
Name: www.l.google.com
Address: 74.125.224.48
Name: www.l.google.com
Address: 74.125.224.52

So it's would appear to be resolving fine on console.

Weird huh, Any ideas?

Check your DNS settings by reading: Why am I being redirected to other sites?

And just to make it more strange, Google.com on IE 9 works fine (inside Parallels VM)

The above problem is also intermittent and happens on my Verizon 4g, and on Comcast.

Everything looks fine there. DHCP DNS assigned. Problem occurs from numerous different WiFi routers, Comcast, Verizon, public WiFi etc.

I'm actually wondering now.. Maybe it's related to IPv6? IIRC google is on IPV6. Could that be causing an issue?

What DNS servers are you using, both in your computer and your router?

Right now the DNS is assigned as 196.168.1.1 and that is the Verizon 4g MiFi device.

At home I have an AEBS on Comcast. Same issues.

Change them to either OpenDNS or Google servers, as shown in the link I posted. See if that resolves the problem.

Thanks I will try that.

FWIW I logged into the MiFI and got the settings it's using:

Gateway: 10.165.96.221
DNS: 66.174.92.14

I'd change those to OpenDNS or Google, as well.

I had severe DNS issues with a Motorola router-modem provided by AT&T. I would have to empty the cache with my browser each time it went bonkers. Trying emptying the cache.
