systemd는 dns cname 레코드에 대한 변경 사항을 해결합니다.

저는 Arch Linux(4.7.2-1-ARCH)가 설치된 PC를 가지고 있습니다. PC는 IP를 얻기 위해 DHCP를 사용하지만 systemd-resolved를 통해 구성한 다른 DNS 서버를 사용합니다. CNAME 레코드가 있는 도메인에서 dig 명령을 사용하면 연결된 A 레코드가 손실됩니다. dig를 사용하고 서버를 수동으로 구성하면 A 레코드가 있습니다. systemd-resolved가 DNS 기록을 변경하는 이유를 아시나요?

추가 정보가 필요하면 알려주시기 바랍니다.

이것은 내 네트워크(systemd-networkd) 구성입니다.

[Match]
Name=ens18

[Network]
DNS=10.0.0.18
DHCP=ipv4

[DHCPv4]
UseHostname=false
UseDNS=false

해결.conf:

# This is a static resolv.conf file for connecting local clients to
# systemd-resolved via its DNS stub listener on 127.0.0.53.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.
