My router is really good at assuring that when I turn off a computer and move it around - it gets the same IP it was using before.
Even if I leave a computer down for a week or more, it will usually regain the same address it had (using the factory DHCP settings on my router).
So it was strange for me this morning, to see one of the NICs on my Linux box has mysteriously changed IPs.
Is there a good log or trail I can follow to try to figure out why/how/when this happened?
BTW, this box has 2 NICs and the other is still using its old address. Furthermore, the system itself has not been reset during this period.
I have messed with the SSH and Apache configuration files (simply to change ports but that shouldn't have done anything to the IP address) and I doubt the connection dropped for any significant period (as the other NIC wasn't effected) - so I am just kinda puzzeled.
