DNS (Domain Name System) records are entries stored in a domain's authoritative zone. They translate a human-readable name into the technical details computers need to reach the right server or service.
Common record types include A and AAAA (IPv4 and IPv6 addresses), MX (mail servers), TXT (verification and email policies such as SPF, DKIM and DMARC), NS (name servers) and CNAME (aliases).
The A and AAAA records reveal which IP addresses uol.com.br currently points to. The MX records list the servers that receive email for uol.com.br, while TXT records hold verification and email-authentication policies.
Each record also has a TTL (time to live) that indicates how long it can be cached. Higher TTLs mean changes take longer to propagate across the internet.
