Redirect domain names from linux dns server - linux

Question

So, the IT department decided to change a bunch of domain names and it broke a bunch of stuff in my lab network. I have a suse linux dns server (which I didn't setup and don't know much about). I was wondering if there was a way I could make it manually resolve ip addresses to the old domain names.
Simply modifying the software in my lab to point to the new domain names wont work (because there are other labs at other sites that will still be using the old domain names).

Answer 1

here are some relevant quotes from this tutorial:
Examples Corporation has been assigned the network 192.0.2.0/24 and internally we are using 10.0.0.0/24.
Let's start serving the external names and IPs, we edit /etc/bind/named.conf.local4 and add:
zone "example.com" {
type master;
file "/etc/bind/db.example.com";
};
and then we create /etc/bind/db.example.com with the following contents:
; example.com
$TTL 604800
# IN SOA ns1.example.com. root.example.com. (
2006020201 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800); Negative Cache TTL
;
# IN NS ns1
IN MX 10 mail
IN A 192.0.2.1
ns1 IN A 192.0.2.1
mail IN A 192.0.2.128 ; We have our mail server somewhere else.
www IN A 192.0.2.1
client1 IN A 192.0.2.201 ; We connect to client1 very often.
So what you want to do is replace "example.com" with whatever domain your programs access, replace "192.0.2.whatever" with your destination ip and remove the "ns1", "mail", "www", "clien1" lines and replace it with
*.yourdomain.com. IN A your.ip.address.255
