DNS Configuration: server can't find ****: NXDOMAIN

Sorry if the question title is not descriptive enough, I'm a noob @ this kind of Linux sysadmin stuff

Hi for a college project I have to configure a Oracle RAC environment, for this task I chose this guide:

I'm currently stuck on setting up my DNS server, this is the expected result from running nslookup on a configured address.

[root@dbwr1 ~]# nslookup dbwr-scan
Server: 192.168.24.1
Address: 192.168.24.1#53
Name: dbwr-scan.localdomain
Address: 192.168.24.43
Name: dbwr-scan.localdomain
Address: 192.168.24.42
Name: dbwr-scan.localdomain
Address: 192.168.24.41

This is my current output:

nslookup node-scan
Server: 192.168.1.1
Address: 192.168.1.1#53
** server can't find node-scan: NXDOMAIN

This is output after checking the named service's status.

systemctl status named

This is my named.conf for configuring the DNS server.

options { listen-on port 53 { 127.0.0.1; 192.168.24.1; }; listen-on-v6 port 53 { ::1; }; directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; recursing-file "/var/named/data/named.recursing"; secroots-file "/var/named/data/named.secroots"; allow-query { localhost; 192.168.24.0/24; }; //empty-zones-enable no; recursion yes; dnssec-enable yes; dnssec-validation yes; /* Path to ISC DLV key */ bindkeys-file "/etc/named.root.key"; managed-keys-directory "/var/named/dynamic"; pid-file "/run/named/named.pid"; session-keyfile "/run/named/session.key";
};
logging { channel default_debug { file "data/named.run"; severity dynamic; };
};
zone "." IN { type hint; file "named.ca";
};
zone "localdomain.com" IN { type master; file "localdomain.zone"; allow-update { none; };
};
zone "24.168.192.in-addr.arpa." IN { type master; file "24.168.192.in-addr.arpa"; allow-update { none; };
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

This is the specified zone localdomain.zone

$TTL 86400
@ IN SOA node1.localdomain.com. root.localdomain.com. (
2014051001 ; serial
3600 ; refresh
1800 ; retry
604800 ; expire
86400 ; minimum
)
@ IN NS node1.localdomain.
localhost IN A 127.0.0.1
node1 IN A 192.168.24.1
node2 IN A 192.168.24.2
node1-priv IN A 192.168.10.1
node2-priv IN A 192.168.10.1
node1-vip IN A 192.168.24.31
node2-vip IN A 192.168.24.32
node-scan IN A 192.168.24.41
node-scan IN A 192.168.24.42
node-scan IN A 192.168.24.43

And the reverse zone:

$TTL 86400
@ IN SOA node1.localdomain.com. root.localdomain.com. (

3H
1H
1W
1H )
@ IN NS node1.localdomain.com.

node1 IN A 192.168.24.1
node-scan IN A 192.168.24.41
node-scan IN A 192.168.24.42
node-scan IN A 192.168.24.43
1 IN PTR node1.localdomain.com.
41 IN PTR node-scan.localdomain.
42 IN PTR node-scan.localdomain.
43 IN PTR node-scan.localdomain.
