Question: What Is A Record And MX Record?

Can an A record point to another domain?

CNAME records must point to another domain name, never to an IP address.

A hostname defined in a CNAME record must have no other resource records of other types (MX, A, etc.), except for DNSSEC records like RRSIG and NSEC..

What is an A record?

An A record is a type of DNS record that allows the address of a computer to be found using its hostname. The “A” in “A record” stands for address. … Your A record allows these DNS servers to have the IP address that corresponds to your domain name.

Do I need an MX record to send email?

No you don’t need an MX record. An MX record designates where email for a domain goes, not where it comes from. Anyone using the MX record as a test to determine if the sending server is valid is doing it wrong.

Where is PTR record stored?

PTR records are not stored within your domain zonefile, they are stored in a zonefile usually managed by your service provider or network provider. Some service providers provide an interface where you can create the PTR record yourself, others require you to submit a support request to create or change the PTR record.

How does PTR record work?

While the main purpose of the Domain Name System is to point domains to IP addresses, a PTR record works in the opposite way – it associates an IP with a domain name. Because of its purpose, a PTR record is sometimes called Reverse DNS Record. … One PTR record can be configured per IP, linking that IP to a single domain.

Can an A record point to two IP addresses?

DNS can hold multiple records for the same domain name. DNS can return the list of IP addresses for the same domain name. When a web-browser requests a web-site, it will try these IP addresses one-by-one, until it gets a response.

What is MX and TXT records?

MX – specifies where the emails for your domain should be delivered. CNAME – specifies redirects from your domain’s subdomains to other domains/subdomains. TXT – used to store text-based information related to your domain. Most commonly used for storing SPF data.

Should I use Cname or a record?

General rules: Use an A record if you manage which IP addresses are assigned to a particular machine, or if the IP are fixed (this is the most common case). Use a CNAME record if you want to alias one name to another name, and you don’t need other records (such as MX records for emails) for the same name.

What is the purpose of MX records?

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

What is a PTR record?

A DNS pointer record (PTR for short) provides the domain name associated with an IP address. A DNS PTR record is exactly the opposite of the ‘A’ record, which provides the IP address associated with a domain name.

What is TXT record for?

TXT records are a type of Domain Name System (DNS) record that contains text information for sources outside of your domain. You add these records to your domain settings. You can use TXT records for various purposes. Google uses them to verify domain ownership and to ensure email security.

Can an MX record point to a Cname?

As stated in the IETF (Internet Engineering Task Force) RFCs (Request for Change), it is not permitted to point an MX record to an alias/ CNAME.

What does an MX record look like?

An MX-record is simply a DNS-entry that tells the sending server (SMTP-server) where to deliver the email. A typical MX-record would look something like this: example.com. 3600 IN MX 0 mail.example.com.

What is difference between NS and DNS?

NS, or Name Server records, are the top-most records attached to your domain. … While DNS (or Domain Name System) records are also public, they are only stored in one specific location. The NS record then responds and tells your computer, “You’ll find the DNS records for that domain on “X” server.”
