option82 is great, but differs from vendor to vender - I use always a
a pitfal is, when you try to give a dslam port a static ip with a
isc-dhcpd, thats not possible. (I have modfied isc-dhcpd to have a fixed
size option82 hardware type).
also pools and leasetimes could be problematic, when getting low.

more security - but not always supported, I have not yet tested or needed
