Do you mean you want the "hostname" command to give different output
depending on which address you telnetted to?  Sorry, you can't do that.
There's just one system hostname, which is set using the "hostname" command
when the system boots; it defaults to the name of the first interface, but
it can actually be anything (I think some versions of Unix have a file
/etc/nodename that can be used to configure this).
