.DNS stub resolver option now supports `no-aaaa` option
With this enhancement, `glibc` now recognizes the `no-aaaa` stub resolver option in `/etc/resolv.conf` and the `RES_OPTIONS` environment variable. When this option is active, no AAAA queries will be sent over the network. System administrators can disable AAAA DNS lookups for diagnostic purposes, such as ruling out that the superfluous lookups on IPv4-only networks do not contribute to DNS issues.

Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (glibc bug fix and enhancement update), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2022:7684 NetworkManager integration is currently missing. If NetworkManager is used to manage /etc/resolv.conf, changes to this file will be overwritten. NetworkManager does not propagate no-aaaa from the interface DNS configuration even if it set there. (In reply to Florian Weimer from comment #15) > NetworkManager integration is currently missing. FYI: reported as bug 2144521. |
