Caleb,

The 169.254.x.x address is from APIPA.
http://support.microsoft.com/?id=220874

APIPA kicks in when you try and get a DHCP address, but none is issued. This
could be from several reasons:
1) No connectivity.
2) No DHCP server, or no available addresses.
3) The DHCP server explicitly filters you out.

If your Dad is the one who looks after the network, should you maybe ask him for
help? Could he maybe have setup filters and blocked all unknown physical
addresses for security reasons?
