Question AWS Lightsail DNS zones are limited to 3 ?

[IrishLaad]

Hi I have 4 instances (different websites) running at the minute. I have reached my limit with 3 DNS zones and I am trying to setup DNS for my 4th website. Do I not need a zone for each website?

Currently my setup is;

red.com
blue.com
yellow.com

I have 3 DNS zones (red, blue, yellow), one for each site.
I also have 3 static IP's(red, blue, yellow), one for each site.

I want to setup a fourth site green.com but I cannot create another DNS zone. What do I do here? Can one zone be used for multiple sites?

I have no training in DNS or anything alike. Thanks for your time.

This:

" I have reached my limit with 3 DNS zones and I am trying to setup DNS for my 4th website. "

If you know that you have reached some limit (3) then why try to setup a 4th zone?

Not sure that I follow having a "limit" if you are able or expecting to be able to establish a 4th.

Full disclosure: Out of my "comfort zone" (no pun intended) but update your post with more information and details.

For example: what happens or does not happen if you create (in what ever manner) a 4th zone?
