It provides a reverse DNS record, also known as rDNS record, by pointing an IP address to the server's hostname. PTR record: also known as Pointer record, points the IPv4 or IPv6 address to its machine's hostname.These are the DNS servers that are authoritative to handle any query related to that domain. NS record: also known as Name Server records, points to the name servers which have authority in managing and publishing DNS records of that domain.For detailed analysis, use MX Record Lookup. MX record: also known as Mail Exchange records, tells which mail exchange servers are responsible for routing the email to the correct destination or mail server.The aliased domain or sub-domain gets all the original Domain's DNS records and is commonly used to associate subdomains with existing main domain. CNAME record: also known as Canonical Name record, creates an alias of one domain name.The four "A" s (AAAA) are mnemonic to represent that IPv6 is four times larger in size than IPv4. But due to the shortage of IPv4, IPv6 was created. For a long time, 32-bits IPv4 addresses served the purpose of identifying a computer on the internet. AAAA record: maps the hostname to 128-bits IPv6 address.That record points the domain name to an IP address. A record: the most basic type of record, also known as address record, provides an IPv4 address to a domain name or sub-domain name.Select any record for lookup or select "ALL" to get all common DNS records for a domain. The DNS records include A, AAAA, CNAME, MX, NS, PTR, SRV, SOA, TXT, CAA, DS, DNSKEY, and many more. To check that you have configured correct DNS records for your domain, use the DNS lookup tool to verify your DNS records so you can avoid any downtime. Therefore, if you changed your web hosting or DNS records, those changes should reflect instantly. Use options to perform DNS lookup either against Google, Cloudflare, OpenDNS, or the domain's authoritative name server(s). The DNS lookup tool fetches all the DNS records for a domain and reports them in a priority list.
