The ADDRESSES array might not have addresses added during PreUp. But moreover, nft(8) and iptables(8) don't like ip addresses in the form somev6prefix::someipv4suffix, such as fd00::1.2.3.4, while ip(8) can handle it. So by adding these first and then asking for them back, we always get normalized addresses suitable for nft(8) and iptables(8). Reported-by: Silvan Nagl <mail@53c70r.de> Signed-off-by: Jason A.
