WeVividWeVividLook up a domain's DNS records.
Browsers don't expose DNS resolution to JavaScript directly, so this uses a small WeVivid server endpoint that performs the DNS query and returns the results. The domain you enter isn't stored anywhere.
A records map a domain to an IPv4 address; AAAA records do the same for IPv6. MX records point to mail servers, NS records list the domain's authoritative nameservers, and TXT records hold arbitrary text often used for domain verification or SPF/DKIM.
A domain simply might not have that record type configured — for example, many domains have no AAAA (IPv6) record, or no MX record if they don't receive email.
