i am very very sorry ,
the zone info of first mail -> zone "bd.baidubce.com." i write wrong;
the wright info is zone "x.bd.bcebos.com."
please just see this mail,
when i use bind-9.11 for my interdns deviceip is 10.1.1.1, i config
zone "x.bd.bcebos.com."
in { type forward ; forward only; forwarders { 10.10.10.10; }; };
1,when i dig @10.1.1.1 x.bd.bcebos.com.
2,10.10.10.10 return record "CNAME bd.bcebos.com., bd.bcebos.com. A 100.67.96.26, A 100.67.96.27" to device10.1.1.1
3,but device10.1.1.1 not return A 100.67.96.26, A 100.67.96.27 to me
4,device10.1.1.1 go to qurey bd.bcebos.com. recursive itself, and get another record 110.242.70.8
i have questions
1,why config is forward only, bind get CNAME & A records from forwarders, but bind do not return A record to me?and query cname domain recursive again itself?
thanks
