I wasn't doing anything in the computer, cron was disabled etc. (I can privately explain values of XX:XX:XX:XX:XX:XX and YY.YY.YY.YY/ZZ.)
It seems that YY.YY.YY.YY received by dhcpcd-3.0* is slightly different than YY.YY.YY.YY received by dhcpcd-3.1.3.

3.1 will be slower as it will ARP check by default 3.0 can ARP check by using the -a option, so add that and you get a farier test. Or use -A with 3.1 to disable the ARP check.

in /etc/conf.d/net dhcpcd_eth0="-a" or dhcpcd_eth0="-A"
(In reply to comment #9) > in /etc/conf.d/net > > dhcpcd_eth0="-A" Thanks. It works. You can add information (via einfo) about dhcpcd_eth0="-A" to pkg_postinst().
Out of curiosity, how to the 3.1 times compare vs 3.0 using the -a option for 3.0?
