Okay so I have registered a domain name with goDaddy.com (mcspy.info), I then have a free hosting company where my website is on (hostinger.co.uk). In the DNS Zone Editor, I have created a new A Host, with the prefix "play" and it points to my public IP address (The one which users currently use to connect to my server.) and the TTL as "1 hour" (14400). However, after waiting some time, when I enter play.mcspy.info to attempt to connect to my Minecraft Server, it won't connect, using my public IP address however works fine.

Any suggestions, fixes on why this doesn't work? If you would like more information, then please ask! Thanks!
