Pencarian DNS gratis untuk domain Anda

Apa itu DNS?

DNS merupakan singkatan dari Sistem Nama Domain. Umumnya dikenal sebagai buku telepon internet, DNS menerjemahkan nama domain menjadi alamat IP, sehingga browser dapat memperoleh informasi yang diperlukan.

Misalnya, setiap mesin di internet, baik laptop atau server web Anda memiliki alamat IP unik. Jadi, jika Anda memasukkan nama domain, misalnya, www.zylker.com, alamat IP masing-masing dipetakan dengan bantuan DNS dan halaman web dimuat dengan sesuai.

Catatan apa yang dicari dalam laporan DNS?

Catatan DNS adalah file teks yang mengandung informasi keseluruhan tentang nama domain tertentu, termasuk alamat IP, nama alias dari domain tersebut, dll. Berikut adalah beberapa catatan DNS umum:

• Catatan: Mencantumkan alamat IPV4 domain.
• Catatan AAAA: Mencantumkan alamat IPV6 host.
• CName: Mencantumkan alamat yang dituliskan merupakan alias atau subdomain dari suatu Domain. Semua catatan CName mengarah ke suatu domain dan bukan alamat IP.
• Catatan MX: Mencantumkan server email SMTP dari domain masing-masing.
• Catatan TXT: Mencantumkan data yang dapat dibaca mesin seperti detail enkripsi, kerangka kerja kebijakan pengirim, DKIM, DMARC, dll..
• Catatan NS - Mencantumkan nama dan detail Server Nama Autoratif dari domain masing-masing
• SOA Record: Contains administrative information about the DNS zone, including the primary name server, hostmaster email, serial number, and timing values for refresh, retry, and expiry.
• PTR Record: Used for reverse DNS lookups, mapping an IP address back to a domain name. PTR records are essential for email server validation.

Understanding Your DNS Lookup Results

When you run a DNS lookup with this tool, the report is organized into the following sections:

• MX Records: Shows the mail exchange servers for the domain, their IP addresses, TTL values, and priority. Lower priority numbers indicate preferred mail servers.
• SOA Record: Displays zone authority details including the primary server, hostmaster contact, serial number, and timing intervals for refresh, retry, and expiry.
• Reverse DNS Lookup: Checks whether the domain's IP addresses have valid PTR records, which is important for email deliverability and server trust.
• Name Server Performance: Tests each authoritative name server for the domain, showing resolved IPs, TTL values, response times, and availability status.
• DNS Traversal: Traces the full DNS resolution path from root servers through TLD servers to authoritative name servers, showing response times at each hop.
• Namespace Server Delegation: Verifies that the parent zone correctly delegates to the domain's name servers and checks for consistent glue records.
