Hello,

Why ? What do you want to achieve exactly ?

> Can a rule work out the IP address of its host?

What address ? A node may have more than one single address, and usually 
does : typically the loopback address range 127.0.0.0/8 and one or more 
addresses assigned to each "real" interface. If a packets arrives in the 
INPUT chain, it implies that its destination address is assigned to the 
node. Otherwise the packet is discarded if the node is a simple host, or 
sent in the FORWARD chain if the node is a router.
