Klo di reverse DNS
Quote:
Preparation:
The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 203.130.244.194 is found by looking up the PTR record for
194.244.130.203.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.
See How Reverse DNS Lookups Work for more information.

How I am searching:
Asking f.root-servers.net for 194.244.130.203.in-addr.arpa PTR record:
f.root-servers.net says to go to ns-sec.ripe.net. (zone: 203.in-addr.arpa.)
Asking ns-sec.ripe.net. for 194.244.130.203.in-addr.arpa PTR record:
ns-sec.ripe.net [193.0.0.196] says to go to dns2.telkom.net.id. (zone: 244.130.203.in-addr.arpa.)
Asking dns2.telkom.net.id. for 194.244.130.203.in-addr.arpa PTR record: Reports that no PTR records exist [from 203.130.196.5].

Answer:
No PTR records exist for 203.130.244.194. [Neg TTL=38400 seconds]

Details:
dns2.telkom.net.id. (an authoritative nameserver for 244.130.203.in-addr.arpa., which is in charge of the reverse DNS for 203.130.244.194)
says that there are no PTR records for 203.130.244.194.

To get reverse DNS set up for 203.130.244.194, you need to speak to your Internet provider. You could also
check with hostmaster@telkom.net.id., who is in charge of the 244.130.203.in-addr.arpa. zone.

Answer:
No PTR records exist for 124.195.15.100. [Neg TTL=3600 seconds]

Details:
ns2.palapanet.com. (an authoritative nameserver for 15.195.124.in-addr.arpa., which is in charge of the reverse DNS for 124.195.15.100)

hm... berarti aku melihatnya ada 2 buar server, SOA dan slave. kalo untuk SOA nya hanya untuk meneruskan informasi domain aja dan slave menyimpan info domain.
si server SOA ini dapat langsung di resolv di internet sedangkan slave di kemungkinan menggunakan jaringan lain yang hanya (mungkin) bisa di akses port 53 aja..

@ fiqqih+Yanuar
silakan lihat DNS Server
