nslookup -type=all xxxx.com
primary name server = xxxx.com
xxxx.com nameserver = dns5.easydns.com
xxxx.com nameserver = ns-1324.awsdns-12.org
xxxx.com nameserver = ns2.dnsmadeeasy.com
xxxx.com nameserver = bdns5.ultradns.net
xxxx.com nameserver = dns3.easydns.net
xxxx.com nameserver = ns-2909.awsdns-49.net
看起来是自己架 DNS server 、但是据我所知、至少Router 53 是不支援 secondary DNS
有人知道该怎么做吗？
