Technical Standards
RFCs, internationalized domain names (IDN), Punycode, RDAP, and related standards.
RDAP (протокол доступа к регистрационным данным)
Modern, structured replacement for WHOIS using JSON over HTTPS.
EPP (расширяемый протокол обеспечения)
Protocol for registrar-registry communication to manage domains.
IDN (интернационализированное доменное имя)
Domain name containing non-ASCII characters from various writing systems.
Punycode
ASCII encoding for internationalized domain names (xn-- prefix).
TTL (время жизни)
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.
Депонирование данных
ICANN-required backup of registration data with a trusted third party.
Распространение DNS
Time for DNS changes to spread across all resolvers worldwide.
Подстановочная DNS-запись
DNS record using * to match all undefined subdomains.
Клеевая запись (Glue Record)
A/AAAA record in parent zone preventing circular nameserver dependencies.
RFC (Запрос на комментарии)
IETF formal document defining internet protocols and standards.
IDNA (Интернационализованные доменные имена в приложениях)
Technical framework governing how international characters are validated and encoded in domain names.
Протокол WHOIS
Plain-text domain lookup protocol on TCP port 43, being replaced by RDAP.
DNS-over-QUIC (DoQ)
DNS encryption over QUIC (UDP port 853), offering lower latency than DoH or DoT.
ECS (подсеть клиента EDNS)
DNS extension sharing partial client IP with authoritative servers for geolocation-based responses.
TSIG (подпись транзакции)
Shared-secret HMAC mechanism authenticating DNS messages between servers.
AXFR / IXFR (передача зоны)
Protocol for replicating DNS zone data from primary to secondary nameservers.
NSEC / NSEC3 (Отказ существования в DNSSEC)
DNSSEC record types cryptographically proving a domain name does not exist.
Запись DNSKEY
DNS record holding the public key used to verify DNSSEC signatures in a zone.
Запись RRSIG
Cryptographic signature record attached to DNS record sets for DNSSEC validation.
