Apa itu cek WHOIS?

WHOIS adalah direktori publik yang mencatat siapa pemegang sebuah nama domain atau blok alamat IP. Hasil pencarian menampilkan registrar tempat domain dibeli, kapan domain didaftarkan dan kapan kedaluwarsa, name server-nya, kode status-nya, serta kontak abuse untuk melaporkan spam atau phishing. Untuk alamat IP, hasilnya menampilkan pemilik jaringan, rentang alamat, dan regional internet registry (ARIN, RIPE NCC, APNIC, LACNIC, atau AFRINIC) yang mengalokasikannya.

RDAP: WHOIS versi modern

Alat ini mengkueri Registration Data Access Protocol (RDAP), penerus protokol WHOIS lama berbasis teks yang menggunakan format JSON terstruktur. Kami menemukan server registry otoritatif untuk setiap TLD atau rentang IP dari file bootstrap IANA, sehingga hasilnya datang langsung dari sumbernya. Untuk sebagian kecil TLD kode negara yang belum menyediakan RDAP, kami beralih ke WHOIS klasik port 43.

Mengapa nama pemiliknya disembunyikan?

Sejak GDPR Uni Eropa berlaku pada Mei 2018, registrar secara default menyembunyikan data pribadi pendaftar perorangan, dan banyak yang menawarkan layanan privasi gratis yang melakukan hal serupa untuk perusahaan. Untuk menghubungi pemilik domain, gunakan formulir kontak registrar atau alamat abuse yang ditampilkan. Baca selengkapnya tentang WHOIS dan privasi (bahasa Inggris).

Memahami kode status domain

StatusArti
active / okKondisi normal tanpa batasan.
client transfer prohibitedKunci dari registrar untuk mencegah transfer tanpa izin. Disarankan.
client update / delete prohibitedKunci tambahan yang memblokir perubahan atau penghapusan.
server hold / client holdDomain tidak dipublikasikan di DNS, sering kali karena belum dibayar atau sedang dalam sengketa.
redemption periodSudah kedaluwarsa dan dihapus, tetapi pemilik sebelumnya masih bisa memulihkannya dengan biaya tertentu.
pending deleteAkan dilepas dan bisa didaftarkan siapa saja dalam waktu sekitar lima hari.

Pertanyaan yang sering diajukan

Bagaimana cara mengetahui kapan sebuah domain kedaluwarsa?

Masukkan domain tersebut di atas; tanggal kedaluwarsa dan hitung mundurnya diambil langsung dari registry.

Apakah cek WHOIS ini gratis?

Ya. Tidak perlu mendaftar dan tidak ada batasan untuk penggunaan normal.

Bagaimana cara cek apakah sebuah domain masih tersedia?

Gunakan cek ketersediaan domain, yang menguji sebuah nama di berbagai ekstensi populer sekaligus.
