Re: Issues encountered with assigning all ones IPv6 /64 address?

Hi,

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.

I discussed this with Hetzner and it seems to be a bug in JunOS 10.3R1.9. - Sander
