Wah jauh2 ngecek DNS record. Itu udah benar koq record2-nya.
Yang harus di cek dulu itu .. DNS Servernya (BIND/NAMED) nya udah jalan belum atau terblok firewall tidak ?
Karena hasil dari
http://www.intodns.com/dimans.co.id ada error :
DNS servers responded ERROR: One or more of your nameservers did not respond:
The ones that did not respond are:
103.255.120.67
cek pakai :
# /etc/init.d/named status
# netstat -an|grep 103.255.120.67:53
# ps -afx|grep named
Kalau BIND/NAMED nya udah yakin jalan ... cek lagi pakai NSLOOKUP atau DIG :
# nslookup
> server 103.255.120.67
> dimans.co.id
# dig @103.255.120.67 dimans.co.id
Lalu, terakhir coba cek firewall ... mungkin ke blok juga ... cek saja :
# iptables -L
Karena, ini saya cek port 53 dari IP 103.255.120.67 ke filter:
