DNS & Infrastructure
DNS resolution, record types, nameservers, and the protocols that power domain name lookups.
DNS (Alan Adı Sistemi)

AAAA Kaydı
DNS record mapping a domain name to an IPv6 address.
CNAME Kaydı
DNS record that creates an alias from one domain name to another canonical name.
MX Kaydı
DNS record specifying the mail server responsible for receiving email for a domain.
TXT Kaydı
DNS record holding arbitrary text data, commonly used for email authentication and domain verification.
NS Kaydı
DNS record that delegates a DNS zone to an authoritative nameserver.
DNS Çözümleyici (Resolver)
Software or service that performs recursive DNS lookups on behalf of clients.
DNS Önbelleği (TTL)
Temporary storage of DNS query results with a Time-To-Live expiration.
Yetkili DNS Sunucusu
Server that holds the original DNS records for a zone and provides definitive answers.
DNS Bölge Dosyası

DNS Bölgesi
Administrative partition of the DNS namespace managed by a single authoritative authority.
PTR Kaydı (Ters DNS)

RFC 6891 extension to the DNS protocol enabling larger messages, DNSSEC, and new option codes.
DNS Amplifikasyon Saldırısı
DDoS technique exploiting open DNS resolvers to flood a victim with amplified response traffic.
Negatif Önbellekleme (NXDOMAIN)
Caching of NXDOMAIN and NODATA DNS responses to prevent repeated queries for non-existent names.
