this is childish
there is a difference between well aware ipv4 and
all sorts of firewalls and proctections configured
or startup in a network with ipv6 enabled without
knowing it or not configured at all
coming up with a "link-local" address inside a network
which is *pure ipv4* on a server means *any* random
device which does the same may bypass all your firewall
rule ssince iptables and ip6tables are two different
services

*why?* there is no ipv6 configuration, BOOTPROTO=static is pretty clear
IPV6INIT=no states clear *no ipv6 for me*
