What is TTL and target when creating CNAME?

I don’t know those and I am begginer to CNAME records and DNS. Please help me guys. I use freenom.com


A CNAME is a common term for DNS, which can be compared to an “alias”. More info: CNAME record - Wikipedia

TTL is time to leave, for how long the DNS information will be cached client-side. After this period of time, it will be re-requested by the client.

Hope it’s more clear

Oh ok. Thanks, what is nameserver for your?

Name servers are the servers that translates your domain into IP address. These servers are provided by the Domain Providers

Name Servers are required for static IP address, Qovery applications have dynamic IP address so you don’t need name servers I guess.
