Setiap kali Anda menggunakan perintah WHOIS tidak mengembalikan informasi yang berguna. Saya biasanya harus pergi ke Godaddy, Dnsstuff atau layanan lain untuk mendapatkan data. Saya mengerti alasannya sebagian besar karena spamming.

Saya hanya ingin tahu bagaimana layanan lain mendapatkan data ini. Apakah mereka menggunakan berbagai jenis perintah WHOIS? Juga bingung tentang beberapa data yang dihasilkan data dari perintah WHOIS hanyalah spam. Contoh melakukan whois google.comgenate situs web spam seperti GOOGLE.COM.ZZZZZZ.THE.BEST.WEBHOSTING.AT.WWW.FATUCH.COM. Dari mana data ini berasal?

Exmaple:

Jawaban singkat untuk pertanyaan Anda, dengan asumsi Anda menggunakan perpustakaan whois debian / ubuntu, adalah menggunakan

$ whois -h whois.crsnic.net "domain google.com"

Inilah jawaban panjangnya.

.COM TLD adalah WHOIS yang Tipis . Saat Anda mengajukan kueri WHOIS, alat WHOIS pertama mengirimkan kueri WHOIS ke Verisign (hostname whois.crsnic.net) dan ekstrak rujukan dari respons.

Secara default, ketika Anda meminta Verisign dari domain example.com, Whois melakukan pencarian string "example.com" yang sangat luas di beberapa objek berbeda termasuk nama domain, nama pendaftar, dan server nama.

Anda dapat memperbaiki kueri dengan menentukan kata kunci, seperti yang dijelaskan dalam dokumentasi Verisign. http://registrar.verisign-grs.com/whois/iframe/help.html?ppath=www.verisigninc.com/products-and-services/domain-name-services/whois&

Perintah di atas melakukan apa yang saya jelaskan. Alih-alih google.com ia mengirim ke Verisign kueri lengkap "domain google.com". Anda harus secara eksplisit melewatkan flag -h karena Whois mencoba menebak nama host untuk query dari query, tetapi akan gagal karena ia tidak akan mengenali query "domain google.com" sebagai domain yang valid.

Inilah hasil dari perintah.

$ whois -h whois.crsnic.net "domain google.com"

Anda meminta semua jenis rekaman, bukan hanya domaincatatan. Dariwhois help

Secara default, WHOIS melakukan pencarian yang sangat luas, mencari semua tipe rekaman untuk pencocokan dengan permintaan Anda di bidang ini: nama domain, nama server nama, alamat IP server nama, dan nama registrar. Gunakan kata kunci untuk mempersempit pencarian.

Kata kunci berikut membatasi pencarian ke bidang TYPE tertentu dalam database: domain Menemukan catatan domain. Cari tahu nama domain, nama pendaftar, server whois dan URL, nama server nama dan Alamat IP, dan tanggal yang diperbarui.

Ada dua kemungkinan perbaikan:

1. Tetapkan opsi domain secara eksplisit:

 whois "domain google.com"

2. Gunakan host whois yang hanya mengembalikan hasil "domain"

whois -h geektools.com google.com 

Lihat Mengapa ada sampah di hasil whois Anda, dan bagaimana Anda bisa menghilangkannya untuk info lebih lanjut.

Saat Anda meminta info WHOIS untuk google.com, ia mencari "google.com" di semua catatan, bukan menjangkar pola sampai akhir seperti yang Anda harapkan.

Dan itu tergantung pada klien WHOIS dan server mana yang dikonfigurasikan untuk digunakan. Saya melakukan riset beberapa tahun yang lalu tentang pengaturan layanan WHOIS internal (saya bekerja di universitas, jadi kami memiliki banyak wilayah kecil dan banyak jaringan) dan dari apa yang saya tahu, ada sangat sedikit struktur yang konsisten dalam data format, sehingga klien harus menggunakan banyak heuristik untuk mengetahui referensi dan semacamnya. Dugaan saya adalah bahwa dnsstuff dan godaddy mungkin memiliki heuristik yang lebih sesuai. Jadi, Anda mungkin hanya mencoba klien yang berbeda.

Lakukan permintaan whois dengan tanda sama dengan di awal sebelum nama domain. Apa yang Anda lihat hanyalah nameserver kesombongan murni yang dibuat di registri, sebagai lelucon yang tidak berguna (tidak ada konsekuensi teknis).
