What is the difference between an A record and a cname record?
The A record maps a name to one or more IP addresses when the IP are known and stable.
The CNAME record maps a name to another name.
It should only be used when there are no other records on that name.
The ALIAS record maps a name to another name, but can coexist with other records on that name..
Can you have multiple Cname records for one domain?
Can I set up multiple A and CNAME records? While you are allowed to create multiple A and CNAME records for the same destination, you can set only one A and CNAME record per source or host name.
Can a Cname point to multiple A records?
You cannot. A CNAME makes one record another name for another. If a record could have CNAMES for two names, it wouldn’t be another name for either of them, but a name for something entirely new, making a CNAME entry inappropriate.
Can an A record have multiple IP addresses?
In either mode, a DNS A record must be defined with more than one IP address (known as DNS A record failover). The first IP address should point to the default, production server, and the other IP addresses should point to identical (or frequently synchronized) redundant servers.
Can 2 domain names point to the same IP address?
7 Answers. Yes, this is an extremely common practice. It is called a Shared Web Hosting: In name-based virtual hosting, also called shared IP hosting, the virtual hosts serve multiple hostnames on a single machine with a single IP address.
What is an A record in DNS?
What is a DNS A record? The ‘A’ stands for ‘address’ and this is the most fundamental type of DNS record, it indicates the IP address of a given domain. For example if you pull the DNS records of google.com, the ‘A’ record currently returns an IP address of: 172.217. 5.78.
Does a subdomain need an A record?
You’ll want to use an A Record for your DNS entry if you have an IP address that the domain/subdomain should point to or if you want to establish a domain/subdomain to be used as the place to point a CNAME.
Can a Cname point to another Cname?
CNAME records can point to other CNAME records, but this is not considered a good practice as it is inefficient. MX and NS records must never point to a CNAME alias.
Is WWW an A record or Cname?
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.
Can an A record point to another domain?
A CNAME record must always point to another domain name and never directly to an IP address. 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 .
Can I have more than one a record?
You can do a lot with A records, including using multiple A records for the same domain in order to provide redundancy and fallbacks. Additionally, multiple names could point to the same address, in which case each would have its own A record pointing to that same IP address. The DNS A record is specified by RFC 1035.
Is an A record required?
“A records (also known as host records) are the central records of DNS. These records link a domain, or subdomain, to an IP address. … A / AAAA record is to redirect your domain to particular IP. If you set NS records for your share hosting then there is no need to set an A record in DNS manager.
Does a Cname need an A record?
Usage of CNAME records means that there is an additional request sent to the DNS servers, which can cause a delay of a few milliseconds. You cannot create a CNAME record for the main domain name (mydomain.com) itself, this must be an A record.
How do I check my Cname record?
