Hi, In our campus we started to use ipv6 a while ago. The problem is we can not connect villa.debian.org from certain ip blocks. Even we disable the firewalls and ACL's in network tools and there is no problem about ipv6 we can connect everywhere except villa.debian.org. Is it possible that those blocks are blacklisted. One of the block that we cannot connect is 2001:a98:30:3::/64 Regards, Lutfi
