This week, we are going to teach you the differences between the four main DNS record types. Before continuing, we recommend that you already have a basic understanding of what is DNS and how it works. A records are the most commonly used record type. If you have ever set up a website, you most likely configured an A record before. These records are the most basic form of a DNS record and almost all other record types we will discuss are based off of A record functionality.

If you are creating a website, then the IP address will usually be given to you by your DNS registrar when you purchased your domain name. A records also have the ability to be pointed to the root of a domain.

For example: if your website is at www. You can learn how to set up an A record here. This is where things start to get a little more complicated. Not too long ago, we realized the world would eventually run out of IPv4 addresses, so IPv6 addresses were developed. Since we developed a new address type, we also had to create a new record type to support it —hence the addition of AAAA records.

You can learn how to configure AAAA records here. These records are typically used to point multiple hosts to a single location, without having to specifically assign an A record to each hostname.

For example: if you moved your blog from news. CNAME records can also be used to point a hostname to another domain or external hostname.

To resolve a CNAME record, the name server must behave slightly differently than it would with a normal query of another record type. You may have noticed that some of the records we have already covered have a few limitations. These records allow you to point the root of your domain to a hostname or FQDN.

Differences Among A, CNAME, ALIAS, and URL records

You can see the full list of advantages and performance benefits here. There are many more record types that exist… you can read about them on our help site.Websites are uniquely identified by IP addresses.

IP stands for Internet Protocol. An IP address is a numerical label which is assigned to a device that connects to the Internet using the Internet Protocol for communication, i. Websites, similarly have a corresponding IP address for each webpage. However, as these IP addresses are not easy to remember, we simplify things by using domain names.

Resource records are database records which are stored in the zone files of the DNS. The DNS is responsible for implementing a distributed, hierarchical, and redundant database for information associated with Internet domain names and addresses.

A Record maps a domain name to one or more IP addresses. For example: going to mydomain. CNAME record, on the other hand, maps a domain name to another domain name. A CNAME record is a type of resource record that specifies that the domain name is an alias of another canonical or generally accepted domain name.

For example: if there are several sub-domains, such as www. Hence, inputting any of the sub-domains will lead to the main domain name, such as mydomain.

Why would you use more than one A record? There are multiple reasons. In that case, you would need to indicate the location of the mail server by an A record. You may also have subdomains for a blog or eCommerce website for which you need to specify an IP address.

Differences Between A and CNAME Records

This can all be done by using an A record. Or, to explain it in simpler terms, it is an alias. Before responsively designed websites were in vogue, it was very popular to create a mobile version of the website in addition to the main website. However, the practice of using responsive design made it unnecessary to have two sets of code.

CNAME records point to another name. CNAME records are often used to simplify something that is otherwise more complex or simply very long.

For example:. If both records were saved together then blog. An A record should always be used to indicate the server address of a particular resource or your web server. For example, your domain name may be examp. Your resulting DNS record would simply be:. Mail server records MX can also point to an IP address. If the mail server were at a different IP address, then it would look like this:.

If you created a separate eCommerce website installation on the same server and it resolves to the same primary domain name, then it may look like this:.

Example of an A-record: Domain: copernica.This can prove convenient when running multiple services like an FTP server and a web servereach running on different ports from a single IP address. One can, for example, point ftp. Then, if the IP address ever changes, one only has to record the change in one place within the network: in the DNS A record for example.

CNAME records are handled specially in the domain name system, and have several restrictions on their use. When a DNS resolver encounters a CNAME record while looking for a regular resource record, it will restart the query using the canonical name instead of the original name. If the resolver is specifically told to look for CNAME records, the canonical name right-hand side is returned, rather than restarting the query.

The canonical true name of " bar. A client will request bar. An A record lookup for foo.

However, a lookup for xyzzy. ANAME records are typically configured to point to another domain, but when queried by a client, answer with an IP address. ANAME record types are going through standardization [7]but there probably exist many non-conforming implementations, so they can do whatever the owner of the DNS platform chooses, including existing at the apex of a zone and existing for domains that receive mail.

CNAME foo. So, for example, a zone must not contain constructs such as: example. MX 0 foo.CName vs. A Record. Web sites are stored in locations that are uniquely identified by a group of numbers, which we know as IP addresses; but to access these sites, we usually type in their corresponding domain names, that are easier to remember.

An A Record is a type of resource record that directly points to the IP address. Instead, it points to another domain address.

Although the point of having a DNS is to get the IP address of a given domain, a CName record is used to identify multiple domain names that point to the same IP address. There are a lot of uses for CName records, but the most prominent is when using multiple services that are running on the same machine or host. An FTP server will have a domain name of ftp.

Despite this, they will be using the same IP address. Therefore, a CName entry will also exist in the database for ftp. When looking for the IP address of ftp.

This procedure is repeated until an A Record is found that provides the IP address being searched. This way, only a single A Record that points to the right IP address is needed. A CName record is very useful, but it can also create a problem that is systemic to its design.

Given the example domain names provided above, it is possible that two CName records exist, where ftp points to www for the first, and the reverse for the second entry. As the query is restarted once a CName entry is found, having those two entries will result in an infinite loop that could crash the server. A Records do not have this problem, as they do not point to another domain name.

Finding a CName record will spawn a new search, while finding an A Record will not. Improper CName records can result in an endless loop, but A Records do not. Cite Ben Joan. February 7, A CName record cannot create a problem. What can possibly create a problem is when someone creates an improper record.

DNS Records

I sold my 2015 Mercedes-Benz C300 4 Matic and wanted an SUV because I retired and want to play in a band and neeed room for my drums. I chose Toyota because they are so reliable. I love this SUV but I'm sorry that I didn't get the Hybrid because the gas mileage is NOT good (very disappointed).

The ride and comfort is excellent and the visability is great. The blind spot alert could have been better, it lights up yellow rather than bright Red and doesn't beep when a car is in the blind spot and you have the blinker on.

All in all it's a great SUV except for the gas mileage.

Its not as quiet as my 2004 4Runner, especially on rough roads. On the Freeway it is quiet, so long as the road surface is good. Seats are comfy but the hip bolstering can make it difficult to get out of the vehicle. Stereo sounded pretty good at a stop or stop light, but the sound quality goes down hill as the speed increases.

Its nimble and the short wheel base takes all of the credit.
