What determines the IP of the site when parking in Cloudflare?

Question

cloudflare

Hello, when you connect a Cloudflare CDN to a site, a random site IP is allocated.
What does it depend on? From the nameserver that Cloudflare asks to assign to the domain, or from what?
What can be done to change Cloud IP? Create a new account in their system or just delete / add a site?

Answer 1

Different tariffs have different pull ip. For example, the business has another pull. Changing your account will not change your IP. Only from the tariff.

Answer 2

it changes from changing the account, I found out in support, also when buying a business plan, they allocate 2 ip when you make a custom ssl certificate

Answer 3

it depends on the random and on the region
