Thanks so much for your response - that rings some bells for me - in my ignorance setting up I went down various paths to 'improve' various aspects of my website (according to the tutorials I followed) Then halfway through the penny suddenly dropped that Lightsail comes with everything I needed for my little site. So I stopped going down that avenue.
So, I have read a little about Cloudfront and feel it is probably over the top for my little sites (I have two very similar shops selling handcrafted items). However, I would fall under the Free tier usage so I could use it for no additional cost - The big question is - would using Cloudfront for my images etc mean my site would run smoother/faster - or as the sites are so small it wont make a discernable difference? Are you able to advise on that - I can then go forward down the correct path for my set up.
I admit to not knowing what IPV4 and IPV6 are and the difference. But from what you say if I decide to go forward without Cloudfront I would delete the IPV6 DNS records.
Where would I find my AWS IPv6 address (if I have one)?
