Option 82 data can sometimes be handy not necessarily for determining 
from which pool to offer an address, but for forensic information later: 
connecting an ip address to a DSLAM or FTTH position, for example. When 
provided an ip address and a window of time, you may need to know which 
of your customers was using that ip during that window. Depending on 
your jurisdiction you may have a legal requirement to store such 
information for possible future warrants.
