Hello,
I want to know is there any way in linux kernel by
which i can come to know that the outgoing packet is
having destination address is of host not of router?
I want to send different data to host/router depending
on dest. address.
regards,
cranium.

What if the router is a host as well? This is quite possible
if the router is a unix/linux box with more than one network
interface.
What problem are you trying to solve by sending different data?

By definition, only hosts have IP addresses. Any router that has an IP address
is also a host.

Very true - if it's a L3 router, it needs that IP address so you have something
to use as a 'next hop' when you try to send to it. If it doesn't have an IP
address, it's a L2 switch/hub and you pretty much *don't* want to talk to it
at all (except to an IP set up as a "management" address, but then you're
talking to it as a host, of course)...
I *think* cranium2003 wanted to do different things depending on whether
the 'next hop addr == dest addr', but I'm failing to see any cases where
you'd want to do that....
