I currently have the ability to edit the following records in my DNS control panel from my hosting provider who provides me with web and email hosting. I have looked in the internet at what these mean but I am still not too sure on what they can be used for and was really looking for some real life examples of what they are used for and when I might want to update them and any more information about them that might be useful. I would really like to learn about these more.
The records I have the ability to change are :
A Record (Address Record)
CNAME Records (Canonical Name Record)
MX Record (Mail Exchange Record)
AAAA Record (IPv6 Address Record)
SRV Record (Service Locator Record)
SPF Record (Sender Policy Record)
TXT Record (Text Record)
If examples could be given for what each are used for and when you might want to change them that would be a great start.
