DNS検証の問題

DNS検証に問題があります。

他のサーバーにpingを送ることができ、トレースパスも機能するため、ルーティングが機能しているようです。

ただし、digを使用すると、そのアドレスに対して「a.root-servers.netが見つかりません」というエラーが発生します。

私はOpenuse Leap 15.4を使用しています。

編集：現在/etc/resolv.conf：

### /etc/resolv.conf is a symlink to /var/run/netconfig/resolv.conf
### autogenerated by netconfig!
#
# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:
#     NETCONFIG_DNS_STATIC_SEARCHLIST
#     NETCONFIG_DNS_STATIC_SERVERS
#     NETCONFIG_DNS_FORWARDER
# or disable DNS configuration updates via netconfig by setting:
#     NETCONFIG_DNS_POLICY=''
#
# See also the netconfig(8) manual page and other documentation.
#
### Call "netconfig update -f" to force adjusting of /etc/resolv.conf.
