Curious whether it's commonplace to find systems that automatically regard .0 and .255 IP addresses (ipv4) as src/dst in packets as traffic that should be considered invalid.
On a separate note, one of my customers discovered over the weekend that if they bring up an all ones IPv6 address in their /64 (2001:db8:1:1:ffff:ffff:ffff:ffff) then they can't exchange traffic with stuff hosted at hetzner.de such as archives.postgresql.org or 1-media-cdn.foolz.us. Seems filtered somewhere inside Hetzner. I found the same if I brought up an all ones address in any other /64 in the same /48 as well. Using ...ffff:ffff:ffff:fffe worked fine. I haven't had time to investigate further or tell them yet, though. Is that sort of thing common? Cheers, Andy -- http://bitfolk.com/ -- No-nonsense VPS hosting
