DNS Lookup - Find All DNS Records Configured for Any Domain
DNS lookup tool offers online lookup for all DNS records configured for a domain. Use this tool to view the most common DNS records of any domain.
What is a DNS record?
DNS records are the mapping files. These are the instructions that reside in the DNS server to provide the following information about a domain.
- What IP is associated with that domain.
- How to handle the DNS requests for that domain.
These records consist of text files that tell the DNS server what to do. DNS records are like a phone book where you have the person's name and contact details. When you enter a domain address (URL) in your browser bar, DNS servers are responsible for providing the domain's server IP information to direct the user to that particular server.
The following are the most common DNS records used to resolve host names into IP addresses.
- A record: That record holds the IPv4 address for a domain.
- AAAA record: That record contains the IPv6 address for a domain.
- CNAME record: That record does not provide an IP address. That is used to alias a hostname to another hostname. In simple, it forwards one domain or subdomain to another domain.
- MX record: It direct mail to mail server. MX record specifies the SMTP mail servers for that domain.
- NS record: That record contains the nameserver's information for the domain. It sets the authoritative nameservers and provides the addresses for that nameservers.
- PTR record: The record directs the IP to a hostname. That record is used to perform the reverse IP lookup and provides a domain name in reverse lookups.
- SRV record: The record specifies the port for specific services. It's like MX but for other communication protocols.
- SOA record: That record stores the admin information about a domain like contact details for the domain's administrator, domain serial number, and information on how frequently should refresh DNS information for this zone.
- TXT record: That record stores the text notes for the domain. Such as opportunistic encryption, SPF, DKIM, DMARC, etc.
- CAA record: That record is certification authority authorization record. It allows a domain owner to state which certificate authorities can issue certificates for that domain. If no CAA record exists, then anyone can issue a certificate for the domain. Subdomains also inherit these records.
- DS record: That record is also recognized as Delegation Signer record. It consists of the unique characters of your public key and its associated metadata like Key Tag, Algorithm, Digest Type, and Digest(cryptographic hash value). That record is used to secure delegations (DNSSEC).
- DNSKEY record: A DNSKEY-record contains a public key used to verify Domain Name System Security Extension (DNSSEC) signatures.
