A-Record

Mit einem A Resource Record wird einem DNS-Namen eine IPv4-Adresse zugeordnet. A Resource Records sind die häufigsten Resource Records im DNS.

Neben der Host-IP-Adressen-Zuordnung werden A RRs auch für DNSBLs oder zur Angabe von Subnetzmasken zu Rückwärtsauflösungen gemäß RFC 1101 verwendet.

Der entsprechende Recordtyp für IPv6 ist AAAA.
