NS1 'A' Record in the SOA record


Hello,

Is it necessary to have a NS1 'A' Record in the SOA record.

Thanks.

Just to clarify... I mean the record that contains the SOA entry.

You cant have a record in a record.

Do you mean 'Can my DNS configuration have a SOA record without NS and A records?' ?

No. I believe RFC requires two NS records. Then you will need A records to resolve the hosts listed in the NS records.

Thanks for your reply, I should have include the SOA record before so my question would be clearer, it's below. The last entry is the NS 'A' record and that's what I'd like to know if it is needed.

Thanks again.

1 $TTL 1D
2 mydomain.com. IN SOA mydomain.com. postmaster.mydomain.COM. (
3 2009061202 ;Serial number
4 3600 ;Refresh
5 1800 ;Retry
6 604800 ;Expire
7 86400 ) ;Minimum
8 ;
9 mydomain.com. IN NS ns1.mydomain.com.
10 mydomain.com. IN NS ns1.secondarydns.com.
11 ;
12 mydomain.com. IN MX 1 mail.mydomain.com.
13 ;
14 mydomain.com. IN A 192.168.1.62
15 mail.mydomain.com. IN A 192.168.1.62
16 ftp.mydomain.com. IN A 192.168.1.62
17 www.mydomain.com. IN A 192.168.1.62
18 ns1.mydomain.com. IN A 192.168.1.62

If you want hosts to be able to resolve the name server's FQDN, then yes it's needed. I'm fairly certain your instance of DNS can operate without A records for the name servers, but it wouldn't be a standard practice.
