When using DHCP as client your computer leaves traces of its mac address, hostname and even some uuid at hosting network.

It is possible to leave lower mark.

Configuration

emerge net-analyzer/macchanger app-arch/sharutils

Add:

File: /etc/conf.d/net
my_name=`cat /dev/urandom | head --bytes 9 | uuencode -m - | head -n 2 | tail -n 1`

preup() {
        [ -f /var/lib/dhcpcd/dhcpcd.duid ] && rm /var/lib/dhcpcd/dhcpcd.duid
        return 0
}

rc_net_eth0_need="firewall"     # optional, if you have firewall
dhcp_eth0="release nontp nonis nosendhost"
dhcpcd_eth0="-h ${my_name} -I ${my_name}"
mac_eth0="random-samekind"
