DMARC Record Checker
Use this tool to lookup and validate your DMARC record.
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting and Conformance), is an email authentication standard, policy, and reporting protocol. It builds on the widely deployed SPF & DKIM protocols and is the only way for email senders to tell email receivers that the emails they are sending are truly from them. Using DMARC enables senders to publish a policy on how email servers should react on inauthentic messages.DMARC Status

SPF Record Checker
Use this tool to lookup and validate your SPF record.
What is SPF?
Sender Policy Framework (SPF) is a simple email-validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain comes from a host authorized by that domain\'s administratorsSPF Status

What is DKIM?
DKIM (DomainKeys Identified Mail) allows senders to associate a domain name with an email message, thus vouching for its authenticity. This is done by "signing" the email with a digital signature, a field that is added to the message\'s header. The recipient MTA can verify the DKIM signature, which gives users some security knowing that the email did actually originate from the listed domain, and that it has not been modified since it was sent.DKIM Status

FCrDNS Record Checker
Use this tool to lookup your FCrDNS record.
What is FCrDNS?
Forward Confirmed Reverse DNS FCrDNS is a DNS technical configuration that shows a relationship exists between an IP address and a hostname. By having FCrDNS, you prove that your IP address is using a sending domain that you own. This relationship provides a form of authentication that some mailbox providers use in their spam filter methodology.FCrDNS Status
Blocklist Record Checker
Use this tool to lookup your blocklist record.
What is Blocklist?
IP blocklisting is a method used to filter out illegitimate or malicious IP addresses from accessing your networks. Blocklists are lists containing ranges of or individual IP addresses that you want to block.

BIMI Record Lookup
Use this tool to lookup and validate your BIMI record.
What is BIMI?
BIMI, or Brand Indicators for Message Identification, is a new standard created to make it easier to get your logo displayed next to your message in the inbox. Not only will this help your visibility, but BIMI is designed to prevent fraudulent emails and aid deliverability, too.
MTA-STS/TLS-RPT Record Lookup
Use this tool to lookup and validate your MTA-STS/TLS-RPT record.
What is MTA-STS/TLS-RPT?
Mail Transfer Agent-Strict Transport Security (MTA-STS) is a protocol that makes it mandatory for any outgoing email from the domain to be TLS encrypted before being delivered to the recipient. Transport Layer Security Reporting is a protocol used alongside MTA-STS that enables the domain owner to receive reports with information on emails that failed to be delivered because the receiving server didn’t support TLS encryption.| Valid MTA-STS record | No |

MX Record Checker
Use this tool to lookup and validate your mx record.
| Preference | Nameserver | IP Address | Organization Name |
What is MX?
MX is the short name for "Mail Exchanger", this is the type of DNS (Domain Name System) record. DNS is the key to a service for a domain. The mail server that sends an email message looks up for MX records for destination domain to find destination mail sever.
A Record Checker
Use this tool to lookup and validate your "a" record.
| IP Address | TTL |
What is A?
An A record is the most basic type of DNS record you can create for your website, and it's used to map a hostname (like "example.com") to an IP address.When your visitors type in a URL like example.com into their browser, their computer sends a request to the DNS server that holds your domain's records. That server will then consult its A records to find out where example.com lives on the internet—that is, which hostname maps to which IP address. Once they know that information, they send back an answer letting the visitor's browser know where to go next.
AAAA Record Checker
Use this tool to lookup and validate your "aaaa" record.
| IP Address | TTL |
What is AAAA?
AAAA records are a type of DNS record that can be used to direct your domain to the IPv6 address (the next major version of the Internet Protocol (IP), which all devices use to communicate with one another on the internet) of a server. It's important to set up AAAA records if you want people who visit your website via IPv6 to be able to connect with it. This makes it easy to route traffic directly to your website.
TXT Record Checker
Use this tool to lookup and validate your "txt" record.
| Content | TTL |
What is TXT?
A TXT record is a text-based resource record that can be added to your domain name system. A TXT record can be used to add additional information about your domain in a human-readable format, such as defining the origin of an email address or the location of a server hosting a website, email spam prevention, domain ownership verification, and the implementation of email authentication protocols like SPF, DKIM, and DMARC.
CNAME Record Checker
Use this tool to lookup and validate your "cname" record.
| Canonical Name | TTL |
What is CNAME?
A CNAME record is an alias that points to another web address. It's what you use when you want to redirect traffic from one website to another. CNAME stands for Canonical Name, and it's a type of DNS resource record that works together with an A record to map a domain name.The most common use case for CNAME records is when you want to redirect your website's URL or use it to host multiple sites on the same server.
SOA Record Checker
Use this tool to lookup and validate your "soa" record.
| Primary name server | Responsible mail addr | Serial | Refresh | Retry | Expire | Default TTL |
What is SOA?
SOA stands for Start of Authority. It's a DNS record that tells the domain name server (DNS) which DNS servers are responsible for your domain.The SOA record contains information about your domain, including the primary email address of your administrative contact and the hostname of the primary server for your domain.
NS Record Checker
Use this tool to lookup and validate your ns record.
| Nameserver | IP Address | Organization Name |
What is NS?
A name server refers to the server component of the Domain Name System (DNS), one of the two principal namespaces of the Internet. The most important function of DNS servers is the translation (resolution) of human-memorable domain names (example.com) and hostnames into the corresponding numeric Internet Protocol (IP) addresses (93.184.216.34), the second principal name space of the Internet which is used to identify and locate computer systems and resources on the Internet.Although it is typically used in reference to DNS, the term name server may also be used for any computer application that implements a network service for providing responses to queries against a directory service which translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component. This service is performed by the server in response to a service protocol request.
Whois Checker
Use this tool to lookup your Whois record.
What is Whois?
Whois is a widely used Internet record listing that identifies who owns a domain and how to get in contact with them. The Internet Corporation for Assigned Names and Numbers (ICANN) regulates domain name registration and ownership. Whois records have proven to be extremely useful and have developed into an essential resource for maintaining the integrity of the domain name registration and website ownership process.
PTR Checker
Use this tool to lookup your PTR record.
What is PTR?
Pointer records (PTR records) are one of the records used by the domain name system (DNS), which acts as a directory for the internet. While DNS typically uses domain names to locate IP addresses, reverse DNS does the opposite with the help of PTR records.| IP Address | Hostname |
