[II3062] Pemilik Domain Detik.com dan List Domain Level 4 di ITB

Yup, jumpa lagi, :D

Postingan kali ini seperti postingan tepat sebelum ini adalah mengenai tugas II3062 - Keamanan Informasi, yang kali ini task nya mengenai DNS:

Tugas kali ini terkait dengan DNS (Domain Name System).
1. Anda diminta untuk mencari pemilik dari domain detik.com melalui whois. (Sebagai tambahan, Anda bisa melihat apakah name server-nya sama dengan yang ada jika di-query dengan nslookup.
2. Berapa banyak domain tingkat 4 (4th level domain) di itb.ac.id dan buat daftarnya. (Yang perlu Anda cari hanya yang *.itb.ac.id.) Tools apa yang Anda gunakan?

Untuk task pertama, saat saya googling dengan keyword 'whois', hasilnya adalah alamat-alamat website yang menyediakan layanan untuk mengetahui keterangan dari suatu domain, ada banyak sekali opsi rupanya, seperti whois.net, whois.domaintools.com, who.is, dan lain-lain, namun entah kenapa tangan ini tergerak untuk mengeklik link whois.web.id, hehe. lalu, setelah memasukkan 'detik.com' di text field nya dan mengeklik tombol ber-caption Whois, keluarlah teks seperti berikut:

Domain servers in listed order:

NS1.DUNIADETIK.COM
NS1.DETIK.NET.ID

dan, voila, terjawablah sudah task pertama ini. :D

Lalu, untuk task yang kedua, karena di *NIX sudah ada utility command host, maka mencoba2lah saya di iMac lab Programming, hehe, di terminal saya ketikkan

host -l itb.ac.id

di mana -l adalah opsi untuk list mode,


dan hasilnya ternyata sangat banyak, namun jika dilihat lebih teliti, ternyata cukup banyak juga yang ternyata diulang-ulang, karena ternyata sebuah domain mempunyai IP address ataupun server lebih dari 1. Maka dengan bantuan sedikit sentuhan code ActionScript3, saya melakukan parsing terhadap list tadi sehingga dari 904 total domain, dihasilkanlah 487 domain yang unique. (source code bisa diunduh di sini - saya pakai FlashDevelop dan FlexSDK 4), dan setelah itu didapatkanlah list domain-domain level 4 di itb.ac.id yang unique sebagai berikut:
