Are you a Comcast customer?  Doing a reverse lookup for 75.75.75.75 points 
to Comcast.  I see that you also have an IPV6 entry.  I'm wondering if your 
router doesn't speak IPV6, in which case you could have the odd behavior you 
describe.  The browsers probably try IPV6 connections first which probably 
don't work.  Going directly to the IP address in my last post should work in 
that case, as should changing the nameservers to 8.8.8.8 and 8.8.4.4 which 
are owned by Google.  If your router does support IPV6, it's probably a 
gateway or configuration issue, in which case you probably need to ask 
Comcast for specific help on how to fix it.
