What is difference between a record and Cname?
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 a Cname record point to an IP address?

Can I have two A records?
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.
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 does an A record work?
Emails are routed through to the IP address which is set in the A-record of the host. … The A-record (or address-record) determines which IP address belongs to a domain name. This record ‘translates’ the domain name to an IP address.
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.
Can 2 domain names point to the same IP address?
It is not possible to provide two domain names for the same Server IP address and get two different SSL certificates (one for each domain name). Also note that the use of Host Headers (which is how you can use a single IP for more than one SSL enabled domain) is not recommended for E-Commerce sites.
What are two types of records?
Records which pertain to the origin, development, activities, and accomplishments of the agency. These generally fall into two categories: policy records and operational records.
What is A and AAAA record?
An AAAA record maps a domain name to the IP address (Version 6) of the computer hosting the domain. An AAAA record is used to find the IP address of a computer connected to the internet from a name. … As with the A records, you can use multiple AAAA records for the same domain in order to provide redundancy.
Can you redirect a domain without hosting?
If you happen to not have a hosting plan and you would like to redirect your domain to another domain, it can be easily done using Cloudflare. First, set up Cloudflare on your domain which you would like to create a redirection from. … Once your domain fully propagates, you can setup redirect on your Cloudflare account.
Can you have two Cname records?
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.
Does an A record have to be an IP address?
A Records: A record only resolves to IP addresses. These records point your domain to the IP address of your website or hosting. Let’s say that you own the domain name name.com which is hosted with us and the IP address of your hosting server is 127.0.
Whats an A record?
An A (address) record is a DNS record that can be used to point your domain name and subdomains to a static IP address. Your DNS management tools allow you to set up A records. Note: The destination of A records can only be IP addresses – such as 66.94. 230.32.
Can an A record point to two IP addresses?
Yes you can have multiple IP’s for the same A record. There’s a few problems with this if used for redundancy purposes… DNS servers and DNS resolvers randomly choose the order of the list of IPs – even though you might configure it a certain way on your DNS Server hosting the zone, resolvers will flip it.
Can two servers have the same hostname?
Question 1: Yes it is possible for multiple devices to have the same hostname on a network, you can simply change the name of any two computers on a network and they will share the same hostname.
Can a hostname have multiple IP addresses?
The hosts file allows no way of distinguishing different “record types” for its resolution. So for hostname to IP address mapping, you only get one IP address per hostname (but multiple hostnames could resolve to the same IP address, which is the opposite).
How long does it take for an A record to update?
Since DNS servers have to update other servers around the world with the new information, propagation can take a long time and is not instant. The general rule is propagation takes 24 hours to complete worldwide. However, in some cases, this can take up to 48 hours, depending on DNS record TTLs.
