DNS & Infrastructure
DNS resolution, record types, nameservers, and the protocols that power domain name lookups.
DNS (Sistem Nama Domain)
Hierarchical naming system that translates domain names into IP addresses.
Server Nama (Nameserver)
Server that stores DNS records and responds to DNS queries for a domain zone.
Rekaman A
DNS record mapping a domain name to an IPv4 address.
Rekaman AAAA
DNS record mapping a domain name to an IPv6 address.
Rekaman CNAME
DNS record that creates an alias from one domain name to another canonical name.
Rekaman MX
DNS record specifying the mail server responsible for receiving email for a domain.
Rekaman TXT
DNS record holding arbitrary text data, commonly used for email authentication and domain verification.
Rekaman NS
DNS record that delegates a DNS zone to an authoritative nameserver.
Pemecah DNS (DNS Resolver)
Software or service that performs recursive DNS lookups on behalf of clients.
Cache DNS (TTL)
Temporary storage of DNS query results with a Time-To-Live expiration.
Server DNS Otoritatif
Server that holds the original DNS records for a zone and provides definitive answers.
File Zona DNS
Text file describing a DNS zone with records for all domains in that zone.
Rekaman SOA
Start of Authority record containing administrative information about a DNS zone.
Subdomain
Domain that is part of a larger domain, created by prepending a label (e.g., blog.example.com).
Alamat IP
Numerical label (IPv4 or IPv6) assigned to each device connected to a computer network.
Resolver DNS Rekursif
Server that performs the full DNS resolution chain on behalf of clients and caches results.
Server Root DNS
Top-level nameservers that direct resolvers to the correct TLD nameservers.
Zona DNS
Administrative partition of the DNS namespace managed by a single authoritative authority.
Record PTR (DNS Terbalik)
DNS record that maps an IP address back to a hostname for reverse DNS lookups.
Delegasi DNS
Transfer of DNS authority for a child zone to designated nameservers via NS records.
DNS Round Robin
Load-balancing technique using multiple IP addresses on a single hostname to distribute traffic.
DNS Sinkhole
DNS configuration that redirects malicious domains to a controlled IP to block or analyze threats.
EDNS (Mekanisme Ekstensi untuk DNS)
RFC 6891 extension to the DNS protocol enabling larger messages, DNSSEC, and new option codes.
Serangan Amplifikasi DNS
DDoS technique exploiting open DNS resolvers to flood a victim with amplified response traffic.
Cache Negatif (NXDOMAIN)
Caching of NXDOMAIN and NODATA DNS responses to prevent repeated queries for non-existent names.
