I have no idea what happened with your machine, because I don't
know how your DHCP server is set up.  In general, there are two
ways in which a DHCP server can give you an IP.  One way is a
configured mapping of MAC addresses to IP addresses (something
like, 0:4:ac:5d:6c:d3 gets 10.20.30.40).  Another way is keeping
a pool of IP addresses (say, from 10.20.30.1 to 10.20.30.254)
assigning addresses from that pool pseudo-randomly (i.e., the
exact algorithm does not matter for the discussion) to anyone who
asks.  Well, there is the third way, too -- mapping some MAC
addresses to specific IP addresses and assign addresses from the
pool to anyone else.

Bottom line: ask the person who configured your DHCP server.  If
it were you, re-configure it to give that specific IP address to
your MAC address.
