Konfiguration binden?

Wenn ich dig static.acer.com ausführt, habe ich eine andere Antwort als wenn ich Googles DNS verwende.

Mit meinem DNS-Server: # dig static.acer.com

; <<>> DiG 9.10.3 <<>> static.acer.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 14150 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1  ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;static.acer.com.

Mit Google DNS:

Was muss ich in named.conf ändern, um meine DNS-Antwort zu ändern?

Host-Befehl verwenden:

# host static.acer.com Host static.acer.com not found: 3(NXDOMAIN) # vi /etc/resolv.conf # host static.acer.com static.acer.com is an alias for static-akamai.gtm.acer.com. static-akamai.gtm.acer.com is an alias for static.acer.com.edgesuite.net. static.acer.com.edgesuite.net is an alias for a1449.b.akamai.net. a1449.b.akamai.net has address 77.67.41.163 a1449.b.akamai.net has address 77.67.41.131 

Wenn ich mit + trace graben wollte, erhielt ich die richtige Antwort:

Irgendeine Ahnung?

UPDATE Nach einem Rndc-Flush habe ich einige Pakete mit tcpdump erfasst:

14:47:55.017422 IP 10.17.2.50.49145 > ns1.acer.com.domain: 63026 [1au] A? static.acer.com.

Jemand versteht was hier passiert? Wenn ich ein öffentliches DNS verwende, funktioniert alles gut.
