Technical Standards
RFCs, internationalized domain names (IDN), Punycode, RDAP, and related standards.
RDAP (Kayıt Verisi Erişim Protokolü)
Modern, structured replacement for WHOIS using JSON over HTTPS.
EPP (Genişletilebilir Sağlama Protokolü)
Protocol for registrar-registry communication to manage domains.
IDN (Uluslararasılaştırılmış Alan Adı)
Domain name containing non-ASCII characters from various writing systems.
Punycode
ASCII encoding for internationalized domain names (xn-- prefix).
TTL (Time To Live)
DNS record value specifying cache duration in seconds.
Anycast DNS
Network method routing DNS queries to the nearest of multiple servers.
DNS-over-HTTPS (DoH)
Protocol encrypting DNS queries over HTTPS for privacy.
DNS-over-TLS (DoT)
Protocol encrypting DNS queries over TLS on port 853.
Veri Emaneti
ICANN-required backup of registration data with a trusted third party.
DNS Yayılımı
Time for DNS changes to spread across all resolvers worldwide.
Joker Karakter DNS Kaydı
DNS record using * to match all undefined subdomains.
Glue Kaydı

WHOIS Protokolü
Plain-text domain lookup protocol on TCP port 43, being replaced by RDAP.
DNS-over-QUIC (DoQ)

NSEC / NSEC3 (DNSSEC Varlık İnkarı)
DNSSEC record types cryptographically proving a domain name does not exist.
DNSKEY Kaydı
DNS record holding the public key used to verify DNSSEC signatures in a zone.
RRSIG Kaydı
Cryptographic signature record attached to DNS record sets for DNSSEC validation.
