I'm thinking of these sorts of things (my faviourite description,
from RFC 2893):

IPv6/IPv4 nodes that perform automatic tunneling are assigned
IPv4-compatible address.  An IPv4-compatible address is identified by
an all-zeros 96-bit prefix, and holds an IPv4 address in the
low-order 32-bits.  IPv4-compatible addresses are structured as

          |              96-bits                 |   32-bits    |
          |            0:0:0:0:0:0               | IPv4 Address |
                       IPv4-Compatible IPv6 Address Format
