Technical Standards
RFCs, internationalized domain names (IDN), Punycode, RDAP, and related standards.
RDAP (등록 데이터 접근 프로토콜)
Modern, structured replacement for WHOIS using JSON over HTTPS.
EPP (확장 가능 프로비저닝 프로토콜)
Protocol for registrar-registry communication to manage domains.
IDN (국제화 도메인 이름)
Domain name containing non-ASCII characters from various writing systems.
퓨니코드
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.
데이터 에스크로
ICANN-required backup of registration data with a trusted third party.
DNS 전파
Time for DNS changes to spread across all resolvers worldwide.
와일드카드 DNS 레코드
DNS record using * to match all undefined subdomains.
글루 레코드
A/AAAA record in parent zone preventing circular nameserver dependencies.
RFC (의견 요청서)
IETF formal document defining internet protocols and standards.
IDNA (응용 프로그램에서의 국제화 도메인 이름)
Technical framework governing how international characters are validated and encoded in domain names.
WHOIS 프로토콜
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 (EDNS 클라이언트 서브넷)
DNS extension sharing partial client IP with authoritative servers for geolocation-based responses.
TSIG (트랜잭션 서명)
Shared-secret HMAC mechanism authenticating DNS messages between servers.
AXFR / IXFR (존 전송)
Protocol for replicating DNS zone data from primary to secondary nameservers.
NSEC / NSEC3 (DNSSEC 존재 부정)
DNSSEC record types cryptographically proving a domain name does not exist.
DNSKEY 레코드
DNS record holding the public key used to verify DNSSEC signatures in a zone.
RRSIG 레코드
Cryptographic signature record attached to DNS record sets for DNSSEC validation.
