If a PC uses DSL to internet, is its IP address different every time ? For example, if you see an IP address from where the email is sent from, how can you trace out that PC ?

It really depends on your service provider. Most services use DHCP to give you an IP address. Some services rarely, if ever, change the address.

What do you mean by "trace out that PC"? What information about the PC are you seeking?

If really depends on the service provider , they maintain a log , from which you can get to know that which IP has been assigned to which host in the DSL network , given him the time.

I believe that unless you are in law enforcement and/or have a court order the ISP will not honor a request for this type of information.

Most ISPs will indeed provide this information on court order only. And even then, they fought it for awhile in the court system. In the US, it wasn't until the Digital Millennium Copyright Act started to get enforced that they started to give in.

There are huge privacy concerns, and no ISP want to be known as not being an advocate for their customers.

Off course , such requests have to be routed through the courts , otherwise
they will be jampacked with such requests.
