  1. Thanks for the help.
    The new appearance is a bit confusing

  2. hi sir, there is another youtuber choose A , instead of CNAME for type, what is the difference?

    1. You can use A record for linking domain to physical IP address. Or use CNAME for linking alias name to another true or canonical domain name.
      Use an A record if you manage which IP addresses are assigned to a particular machine or if the IP are fixed. Use a CNAME record if you want to alias one name to another name.
      Usually A name is faster than CNAME because CNAME results 2nd DNS lookup for the domain name specified in the CNAME
