Is CNAME an A record?
A Canonical Name or CNAME record is a type of DNS record that maps an alias name to a true or canonical domain name. CNAME records are typically used to map a subdomain such as www or mail to the domain hosting that subdomain’s content.
What is the A record?
An A record maps a domain to the physical IP address of the computer hosting that domain. Internet traffic uses the A record to find the computer hosting your domain’s DNS settings. The value of an A record is always an IP address, and multiple A records can be configured for one domain name.
Can CNAME and A record be the same?
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.
Is CNAME or A record faster?
“A” records are generally faster than CNAME records. A CNAME is like an alias, it results in a second DNS lookup for the domain name specified in the CNAME.
What is the difference between CNAME and alias record?
A CNAME record redirects DNS queries for a record name regardless of the record type specified in the DNS query, such as A or AAAA. In the response to a dig or nslookup query, an alias record is listed as the record type that you specified when you created the record, such as A or AAAA.
What is record and types of record?
Records include books, letters, documents, printouts, photographs, film, tape, microfiche, microfilm, photostats, sound recordings, maps, drawings, and a voice, data, or video representation held in computer memory.” Records are retained for administrative, financial, historical, or legal reasons.
What is A record example?
As an example, an A Record is used to point a logical domain name, such as “google.com”, to the IP address of Google’s hosting server, “74.125. 224.147”. These records point traffic from example.com (indicated by @) and ftp.example.com to the IP address 66.147.
Do I need both a record and CNAME 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.
Can you have a CNAME without A record?
You cannot create a CNAME record for the main domain name (mydomain.com) itself, this must be an A record. For example, you cannot map mydomain.com to google.com, however, you can map google.mydomain.com to google.com. MX or NS (nameserver) records may never point to a CNAME record, only A records.
When should CNAME be used?
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. Use an ALIAS record if you’re trying to alias the root domain (apex zone), or if you need other records for the same name.
