What is an A Record?

An “A record” (also known as a host record) is a type of DNS entry that indicates which IP address corresponds to a domain name.

More About A Records

The “A” in A record stands for address. This type of record indicates the IPv4 IP address for any given domain. When a user visits a website, their browser looks up the corresponding A record through the DNS. The browser sends a query, and if a record exists, it receives information about which IP address to connect to.

DNS A records are also critical components of DNS-Based Blackhole Lists (DNSBL). These lists are compilations of IP addresses linked to malicious operations, such as spamming. Services like email providers rely on DNSBLs to flag IP addresses as spam.
