Cname chain resolution using forward ( CNAME&A returned but no use A)
hi admin, when i use bind-9.11 for my interdns deviceip is 10.1.1.1, i config zone "bd.baidubce.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., 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, but bind get CNAME & A,bind do not return A to me,and query cname again itself? thanks
