Setup of domainname not correct DNS ?

Hey All,

I changed to DO but since our domain already has a DNS server I don’t think I need to use DO’s DNS. However locally it doesn’t work, and I would ask you expert whats going wrong.

Seems : juridischforum.be works, but www.juridischforum.be is giving ERR_NAME_NOT_RESOLVED

[root@juridischforum ~]# dig juridischforum.be NS

; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.30.rc1.el6_6.3 <<>> juridischforum.be NS

What I setup is :

ftp	A	178.18.91.128	
juridischforum.be.	A	128.199.41.151	
localhost	A	127.0.0.1	
mail	A	178.18.91.128	
pop	A	178.18.91.128	
smtp	A	178.18.91.128	
www	A	128.199.41.151	
juridischforum.be.	NS	ns1.dot-01.nl.	
juridischforum.be.	NS	ns2.dot-01.nl.	
juridischforum.be.	MX	10 mail	
juridischforum.be.	TXT	"v=spf1 a mx ip4:178.18.91.128 ~all"

I only changed www (A) & juridischforum.be. (A).

Any tips ?
