I'm a newbie to DNS so bear with me. My company host several websites that are registered at Register.com. The sites are currently using register.com's DNS servers which are:
dns5.register.com
dns6.register.com
What I want to do is replace Register.com's DNS server entries with my own (here below) for each of the sites we have registered there.
ns1.mycompany.net
ns2.mycompany.net
I have just installed Red Hat Linux 8.0 on a machine we have here that is going to be our DNS server. I have seen some examples but like I said I'm new to the DNS world and could use some assitance. I running BIND version 9.1.2.
The machine's IP address with Red Hat Linux 8.0 that will be the DNS server is (e.g. 67.1.2.3)
The machine's IP address that has the web server with the sites on it is (e.g. 67.1.2.10)

Here are the contents of my file db.mycompany.net in the /var/named directory:
$TTL 3h
mycompany.net. IN SOA ns1.mycompany.net. al.ns1.mycompany.net. (
1 ;Serial
3h ;Refresh after 3 hours
1h ;Retry after 1 hour
1w ;Expire after 1 week
1h) ;Negative caching TTL of 1 day
; Name servers
mycompany.net. IN NS ns1.mycompany.net.
mycompany.net. IN NS ns2.mycompany.net.
; Addresses for the canonical names
localhost.mycompany.net. IN A 127.0.0.1
ns1.mycompany.net. IN A 67.1.2.3
ns2.mycompany.net. IN A 67.1.2.4
; Multi-homed hosts
;I not sure if I need this so it's none for now.
; Aliases
server1.mycompany.net. IN CNAME ns1.mycompany.net.
server2.mycompany.net. IN CNAME ns2.mycompany.net.
; Interface specific names
;I not sure if I need this so it's none for now.
Here are the contents of my file db.67.1.2 in the /var/named directory:

Here are the contents of my file db.127.0.0 in the /var/named directory:

Here are the contents of my file named.conf in the /etc directory:
// generated by named-bootconf.pl
options {
directory "/var/named";
/*

* port by default.
*/
query-source address * port 53;
};
//
// a caching only nameserver config
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "eltran.net" IN {

type hint;
file "db.cache";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
include "/etc/rndc.key";
I'm not real sure where in the files I need to add my 7 websites. If there are any shortcuts, loop-holes or pitfalls I should know about or watch out for please feel free to voice your knowledge. I know I'm asking for a bit much but assistance would be greatly appreciated!
