Can be pinpointed to what city one is typing from? Or just the state?
It depends.
If you are subscribing to a service at home and get your net connection that way, then you go through many of their servers.
When you hit other sites, it is likely you are going through your provider's servers, and then going out to the site that you hit, and then back to your computer through your provider.
As a result, when the site traces you, depending on how your provider is naming their systems, it might look like newyork1234.attbi.com and that means that you live close enough to the new york region that they sent you through that server.
The more narrow view of it where you can get really spcific is at universities.
I can remember my machine in college had an ip that would map to student99ess.williams.edu or something very much like that.
That points directly at me and makes it very clear who is looking - but again, it doesn't mean that it was me at that machine - it just means it was my machine.
There are many ways around it.
the short answer is that Joe User can't find out too much. The mods can find out a little.
If the FBI really wanted to, then they would simply get the paperwork to get George's servers, go through the IPs, then go to your service provider and do the same.
Service providers are notoriously helpful in finding people (their customers) for large government agencies.
They are notoriously not helpful for random Joe Users find their customers.
