Ive setup a A record on a public DNS server to point to an internal IP. For example myTV.google.co.uk (I know my domain isnt google, its just an example) to point to 192.168.1.145, when I ping myTV.google.co.uk it doesnt resolve to any IP address, and when I try it using my browser I get page cannot be displayed.
Its always fascinated me why it doesn't work as from my understanding it should just pull the IP from the DNS record and then point to an internal IP, it shouldnt matter the DNS server cannot see it.
Is there an issue doing this? I know its probably not best practise, but assumed this is an easier way of doing a few items without setting up a DNS server at home.
Thank you in advance
