Hi, all, I got an additional entry when I run “netstat –rn”
on my fedora host, an “169.254.0.0 …” entry appears without
being invited. I know that 169.254.0.0/16 is a private address block for some
kind of special purposes, and it appears in “ifup” script, But my
question is: what does this entry mean? And How to get rid of it if it
does nothing except bring security holes? Since it is routable now through my hosts’
exneral interface, ridicules.. [ root@example network-scripts ] netstat -rn Kernel IP routing table Destination
