Hello,
I have an issue configuring delegated subdomain zone from one NS to another one.
For security reasons I will obviously not put real domain data (I imagine you
will understand).
Let's suppose that the delegated subdomain is: midominio.principal.hosting.com
If we make a "dig" query, putting the hosting server's NS as the domain name
server:
dig @ns1.hosting.com midominio.principal.hosting.com
; <<>> DiG 9.10.3-P4-Debian <<>> @ns1.hosting.com
midominio.principal.hosting.com
; (1 server found)
;; global options: +cmd

>From which we deduce several things:
1. That in the zone principal.hosting.com of the main server of the hosting
there are created two registers of type A:
* sb1.principal.hosting.com. 125 IN A xxx.xxx.xxx.52
sb2.principal.hosting.com. 125 IN A xxx.xxx.xxx.53
2. That the authorized DNS servers on the subdomain
midominio.principal.hosting.com are:
sb1.principal.hosting.com y el sb2.principal.hosting.com
Having said that, in my vps I have defined the following:
; BIND reverse data file for empty rfc1918 zone
;
; DO NOT EDIT THIS FILE - it is used for multiple zones.
; Instead, copy it, edit named.conf, and use that copy.
;
$TTL 86400
@ IN SOA sb1. sb2. mail. (
10 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
86400 ) ; Negative Cache TTL
; REGISTROS
NS sb1.principal.hosting.com.
NS sb2.principal.hosting.com.
IN MX 10 mail.midominio.principal.hosting.com.
sb1 IN A xxx.xxx.xxx.52
sb2 IN A xxx.xxx.xxx.53
www IN A xxx.xxx.xxx.53
mail IN A xxx.xxx.xxx.53
webmail IN CNAME mail
* IN A xxx.xxx.xxx.53
However I can not get it to solve for example
www.midominio.principal.hosting.com What am I doing wrong?.
Thank you very much in advance
