Address Spaces

The 802.11 standard does permit different address spaces for the following
disparate areas: distribution system, wireless media, and wired LAN
infrastructure.
Note that the actual 802.11 standard only describes addressing when
dealing with a wireless medium; however it does facilitate integration
with 802.3 wired Ether-networks.
Address compatibility is maintained throughout all the different flavors
of 802.11 since in most of these installations, the distribution system
is an 802.11 wired LAN that has all three logical addressing spaces
exactly the same leading; thus, there is little or no distinction between
these areas from the point of view from anyone trying to attack your
wireless LAN.
