mirrorlist.centos.org无法解析问题求助

最近碰到个头疼的问题：我能正常解析centos.org，但就是解析不了mirrorlist.centos.org，换了不同的公共DNS服务器也没用。下面是我执行相关命令后的输出，有没有大佬能帮忙分析下原因？

执行nslookup mirrorlist.centos.org的输出： #

rosdi@H-TQ0nmTkQIbRhN:~/test_ssl$ nslookup mirrorlist.centos.org
Server:         1.1.1.1
Address:        1.1.1.1#53

** server can't find mirrorlist.centos.org: NXDOMAIN

执行nslookup centos.org的输出： #

rosdi@H-TQ0nmTkQIbRhN:~/test_ssl$ nslookup centos.org
Server:         1.1.1.1
Address:        1.1.1.1#53

Non-authoritative answer:
Name:   centos.org
Address: 52.56.83.118
Name:   centos.org
Address: 81.171.33.201
Name:   centos.org
Address: 81.171.33.202
Name:   centos.org
Address: 2001:4de0:aaae::202
Name:   centos.org
Address: 2a05:d01c:c6a:cc02:225e:ab54:d58c:8b14
Name:   centos.org
Address: 2001:4de0:aaae::201

查看/etc/resolv.conf的内容： #

rosdi@H-TQ0nmTkQIbRhN:~/test_ssl$ cat /etc/resolv.conf
nameserver 1.1.1.1
nameserver 8.8.8.8

执行dig mirrorlist.centos.org的输出： #

rosdi@H-TQ0nmTkQIbRhN:~/test_ssl$ dig mirrorlist.centos.org

; <<>> DiG 9.18.24-0ubuntu5-Ubuntu <<>> mirrorlist.centos.org
