Hi Eric, Would you mind expanding on this? I have little operational experience with IPv6 RFC 4193 addresses and I expect most folks here are in the same boat. I understand that glibc would only be involved in setting the order in which DNS lookup results are returned to a program. Is that correct? When I look at my local /etc/gai.conf, it doesn't call out fc00::/7 for different treatment than any other IPv6 address. For off-Internet use, where does that end up creating a problem?
