What is better CNAME or A record?

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.

Is a CNAME the same as an A record?

Difference Between A and CNAME

An A Record maps a hostname to one or more IP addresses, while the CNAME record maps a hostname to another hostname.

What is the difference between A and CNAME DNS records?

An A record points a name to an IP . A CNAME record can point a name to another CNAME or to an A record.

Do I need an A record if I have a CNAME?

Can I have both CNAME and a record?

A CNAME record cannot co-exist with another record for the same name. It's not possible to have both a CNAME and TXT record for www.example.com . A CNAME can point to another CNAME, although this configuration is generally not recommended for performance reasons.

What is the advantage of CNAME?

The most popular use for CNAME is that we can use more than one name to map to a single computer FQDN. This makes it easier to manage multiple applications, such as FTP server, POP server and IIS server, which are hosted on the same server.

Does a CNAME change the URL?

In other words, CNAME record is not redirecting anything but only points your domain or subdomain to the IP address of the destination hostname. So, if the IP of the destination hostname changes, you won't need to change your DNS records as the CNAME will have the same IP.

What is the difference between CNAME and A record subdomain?

CNAME and A records are often confused with each other, but there are differences. First, an A record can only connect the primary parent domain to the corresponding IP address. On the other hand, CNAME records link the parent domain to its alias or subdomains.

What is the advantage of CNAME?

The most popular use for CNAME is that we can use more than one name to map to a single computer FQDN. This makes it easier to manage multiple applications, such as FTP server, POP server and IIS server, which are hosted on the same server.

What is the primary benefit to a CNAME setup?

A partial ( CNAME ) setup allows you to use Cloudflare's reverse proxy while maintaining your primary and authoritative DNS provider. Use this option to proxy only individual subdomains through Cloudflare's global edge network when you cannot change your authoritative DNS provider.

Can CNAME point to another domain?

The CNAME is commonly used instead of an A record, which is a type of DNS record that shows the IP address of a domain. CNAME records must point to a domain and not an IP address. A domain with a CNAME record can either point to another domain with a CNAME record or to a domain with an A record.

Does CNAME affect SEO?

In SEO language, the CNAME can be thought of as a record that specifies a canonical domain at the server level. The good news is that making changes in CNAME does not impact search engine rankings.

Is a CNAME a proxy?

A partial ( CNAME ) setup allows you to use Cloudflare's reverse proxy while maintaining your primary and authoritative DNS provider. Use this option to proxy only individual subdomains through Cloudflare's global edge network when you cannot change your authoritative DNS provider.

Does CNAME need a dot at the end?

This will usually look like "cs-example.delib.net.", "da-example.delib.net. or "sim-example.delib.net." for example. The dot on the end is important and must not be omitted. You need to instruct your technical team to create the CNAME record as soon as possible.
