About DNS Lookup (A Record)

A records are the classic DNS mapping from a name to an IPv4 address. Use this lookup to confirm where a website or mail host points, check TTL, and identify the network (ASN) behind the IP.

From the report you can jump to reverse DNS or blacklist checks on the same IP, or review SPF/DMARC for the parent domain.

Frequently asked questions

What is a DNS A record?

An A record returns one or more IPv4 addresses for a hostname so browsers and mail systems know where to connect.

Can a hostname have multiple A records?

Yes. Multiple A records are often used for load balancing or redundancy. Clients may pick any of the returned addresses.
