DNS CNAME RECORD LOOKUP DETAIL

CNAME (Canonical Name) is a type of DNS record that is used as an alias for
another domain.


WHAT IS DNS ?

DNS (Domain Name System) is a service that translates domain names into IP
addresses. Users can easily remember domain names, but computers only understand
IP addresses that’s why we need DNS. For example, without this service, you have
to type '185.60.216.35' in your browser instead of www.facebook.com to access
Facebook. IP - Domain mappings are kept on DNS servers. You can query those
matches on securityforeveryone.com

There are two types of IP addresses IPv4, and IPv6. IPv4 address looks like
these:

            8.8.8.8
            127.0.0.1
            255.255.255.255

IPv6 addressed looks like these (all of them are the same IP):

            ::ffff:808:808
            0:0:0:0:0:ffff:0808:0808
            0000:0000:0000:0000:0000:ffff:0808:0808


WHAT IS DNS CNAME RECORD?

CNAME (Canonical Name) is a type of DNS record that is used as an alias for
another domain. Let's give a real-life example. You bought a domain such as
securityforeveryone.com then you offer an online email service. To do that
you've created a new subdomain such as email.securityforeveryone.com. However,
you found out that some email clients use the webmail subdomain as default. In
that case, you can use a CNAME record to map webmail.securityforeveryone.com to
email.securityforeveryone.com. CNAME records must point to a domain name, not an
IP address.

Also, another example of using CNAME records is using multiple ports of the same
IP addresses. You can use ftp.securityforeveryone.com (21),
tomcat.securityforeveryone.com (8080), apache.securityforeveryone.com (80,443)
on the same IP addresses. All of them can point to securityforeveryone.com in
the CNAME records. With that, when you move your server to another IP address
you have to change securityforeveryone.com's A record only.


HOW TO TEST DNS CNAME RECORD?

Simple. Write your domain on the form at the top of the page to check cname
records, that's all. Using Security for Everyone’s free cname lookup, you can
get cname records and find all cname records for a domain as well as cname
record check. Generally, people use CNAME to points to another subdomain or main
domain. You can use DNS CNAME lookup tool to get them.

Or if you are using a Linux or an OS X operating system, open the terminal and
type dig -t cname yourdomain.com. If your domain has a valid cname record, it
would look like that:


          dig -t cname securityforeveryone.com
          ;; ANSWER SECTION:
          www.securityforeveryone.com.	168	IN	CNAME	securityforeveryone.com.

If you are using Windows open PowerShell and type Resolve-DnsName -Name
yourdomain.com -Type cname.


SOME ADVICE FOR COMMON PROBLEMS

If you can not see CNAME records that you want, you need to go where you manage
the DNS records (usually the hosting provider panel) and check CNAME records. Do
not forget that, CNAME records must be a domain name. And must be the only
records for the related subdomains.

Also, if your CNAME record shows another domain name, make sure that the domain
name is registered by you. If it falls into the hands of malicious people, you
may experience a violation of information security.
