Howdy pardners!

My Mac will not connect to the internet via an Ethernet cable. My PC does this without a single problem.
When I try to connect to the internet via an Ethernet cable (that works fine on the PC), I am given 2 opportuninties:

Make the computer configure IP settings itself
or
Configure manually

When I do the manual configuration, I don't know what to type and where. My ISP does not have very good customer support (I live in Sweden).
The automatic configuration does not work (obviously).

I open cmd.exe on the PC and type "ipconfig"

This is my result:

Microsoft Windows [Version 6.1.7601]

Can you make your settings look like THIS?

Automatic configuration, using DHCP. And are you using a proxy too?

I think the problem you've got there, is it looks as if your PC is picking up a public IP.
I did a lookup on 83.251.160.69 (as mentioned in the ipconfig from your PC)

IP: 83.251.160.69
Decimal: 1408999493
Hostname: c83-251-160-69.bredband.comhem.se
ISP: Com Hem AB
Organization: Com Hem AB
Services: None detected
Type: Broadband
Assignment: Static IP

I've no idea on what your home network arrangement is, as you don't say. But if you're using a router, I'd look on there and see if you have any DMZ or public settings enabled.
If you don't, then I do hope you have a decent firewall there as that PC you have connected is directly on the internet and not behind a firewall.

So it looks to me as if you have a configuration issue with your router. Get that checked first, then post back with your specific networking setup.

I turned my computer in for service to an Apple Store. Turned out it was a hardware problem (ethernet port somehow broken).

Thank you for your efforts!
