You take it to a shop that offers sharpening services and ask them to do it.

If your knife blunts after cutting paper, it's a very poor quality knife.

Customer A from phone-line B is assigned IP C at Time D
Customer A from phone-line B with IP C logs off at Time D, IP C returned  
to pool

To put it another way you're charged per unit (normally megabyte) for  
information downloaded to your mobile, how does your telecom provider know  
that's you getting that data?

Oh no of course not, it's also not likely that the DVLA will hand out  
information to anyone who sets up a Parking Enforcement company and can  
fill in an online form.

Referrer address = http://www.google.co.uk/search?q=   test    
&ie=UTF-8&oe=UTF-8&hl=en&btnG=Google+Search&meta=cr$3DcountryUK$7CcountryGB  
even features on some sites now with "[IP address] has landed on this site  
searching for [test]" even tries to resolve the IP Address to a place  
based on the ISP - used to have me as Brum now it thinks I'm in  
Cheltenham. And all that without the ISP logs ;-)

IPs are not given out at random.  Each ISP has a range that they are allowed 
to assign. The IP address can be tracked back to the ISP. From there, 
depending what records the ISP keeps, they can probably tell what username 
was usign that IP at that time.

If they were given at random, there would be IP conflicts

Yeah, and some sites manage to figure out that I'm in Milton Keynes.

Do you have *any idea* how many people live in Milton Keynes? ;-)

Yes, I'm well aware of that. I meant they're assigned at random from the 
pool of addresses belonging to that ISP.

This is the part that I doubt.

Sure they do. It's in the http header.

My blog stats page gives me back the all search terms people used to reach 
my blog. It does that by checking and recording the http referrer for each 
visit and parsing the search terms out if its a search engine.

What use would an ISP have for recording this information?
