[PLUG] Question on RTNETLINK's purpose as used in Ubuntu

[website reader]

Does anyone know the purpose of RTNETLINK as being used in Ubuntu
distributions?  I found that apparently this program was monitoring my
network connections and a man page lookup shows that it is used to
change network connections in the kernel.

The first sentence of the man page reads "Rtnetlink allows the
kernel's routing tables to be read and altered."
