All of you may have the same wonder what’s going on in my DNS servers, and what are those setting all about. It finally came to my attention, that without actually knowing what’s each part of setting is used for, it won’t function as I like it to be. Therefore, I had a bit of investigation about DNS various settings and here are some definitions and my explanation to them.
If you have no technical background, you can still read it, so that you would have a basic idea of what’s all the names about, and for. So that in the future, people can’t fool you around by telling you all the technical terminologies that no man on earth (without technical knowledge) can understand.
Here you go:
“A Record”:_
“A Record”, which appear to be on top of your domain management console, which pretty obvious this is the most important setting of all time in your DNS to resolve your host or domain.
A “A Record” is whenever you want to assign an particular IP address to your domain or subdomains. Suppose you have a domain name which for example : mydomain.org, what this “A Record” for is it assign an IP address to your domain, hence in the future, all request to this domain (for example: http://abc.mydomain.org) will be directed to your specified IP address, which should be your Server address.
“CNAME”:_
“CNAME” is used for whenever you want create a new subdomain to an already existing A record; i.e. you can make “www.mydomain.org” to “mydomain.org”, to which there is already an IP address assigned.This enables you to have as many subdomains as needed without having to specify the IP for every record.
To use a CNAME if your domain needs to run more services pointing to the same IP. This also ease the process when changing domain IP address, only 1 IP address is required to change and all services are remain in CNAME.
Those two terminology are all we needed so far to create our own custom DNS setting. Hope this help guys out there looking for answers.
