MX Record Lookup

An MX lookup is a process of querying the Domain Name System (DNS) for the mail exchange (MX) records of a domain name. MX records specify the mail servers responsible for accepting email messages on behalf of a domain name.

This tool allows you to check mx records of any public domain without any hassle. The list of MX records will include the following information:

Mail server name
Mail server IP address
Mail server priority
Mail server organisation
Mail server country origin
Mail server Time To Live (TTL)
Mail server Autonomous System Number (ASN)

What are MX Records?

A mail exchanger (MX) record is a type of resource record in the Domain Name System (DNS) that specifies a mail server responsible for accepting email messages on behalf of a domain name. It is possible to configure several MX records, typically pointing to an array of mail servers for load balancing and redundancy.

The MX record contains the following information:

Mail server name : The name of the mail server that is responsible for accepting email messages for the domain name.
Mail server IP address : The IP address of the mail server.
Mail server priority : A number that indicates the order in which the mail servers should be tried when delivering email messages. The lower the number, the higher the priority.

What is Domain Name System (DNS)?

The Domain Name System (DNS) is a hierarchical naming system for computers, services, and other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participants. Most prominently, it translates easily memorised domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols.

DNS is a distributed system, which means that the DNS database is stored on multiple servers across the Internet. This makes it more reliable than a centralised system, as it is less likely to be affected by a single point of failure.

What are DNS records?

A DNS record is a type of resource record that is stored in the Domain Name System (DNS). DNS records contain information about a domain name, such as its IP address, mail servers, and other properties.

A records : A records map domain names to IP addresses. This is the most common type of DNS record and is used to point domain names to web servers.
AAAA records : AAAA records are similar to A records, but they are used to map domain names to IPv6 addresses.
CNAME records : CNAME records create an alias for a domain name. This means that a CNAME record can be used to point a domain name to another domain name.
MX records : MX records specify the mail servers for a domain name. This is used to deliver email messages to a domain name.
NS records : NS records specify the name servers for a domain name. This is used to locate the DNS servers for a domain name.
TXT records : TXT records can be used to store arbitrary text data for a domain name. This can be used for a variety of purposes, such as adding security features or configuring email servers.

DNS records are an important part of the Domain Name System. They allow users to easily access websites and other resources by using domain names. DNS records also provide other important functions, such as providing information about resources, caching DNS information, load balancing, and security.
