Package: libc6 Version: 2.31-13 Severity: important Tags: ipv6 X-Debbugs-Cc: d...@darkboxed.org
Dear Maintainer, glibc currently limits the number of nameserver directives in resolv.conf to 3. On IPv4/6 dual-stack hosts this can be quite limiting. When redundant nameservers are available we can either choose to have redundancy on v4 or v6 which is unsatisfying. I'm not aware of this problem having been discussed in Debian before, but Ubuntu has an open bug[1] for it. There also is a surprisingly insightful Stackoverflow post[2] on how one might go about increasing MAXNS without an ABI break.
