The protocol used when using ping

What protocols are used when using ping www.xxx.com in a local area network?

Through the DNS protocol, the domain name followed by ping is converted into ip address. (the transport layer protocol used by DNS is UDP)

Through the ARP resolution service, the MAC address is resolved from the ip address for transmission at the data link layer.

Ping is to test whether another host is reachable, send an ICMP echo request to the target host, and wait for the ICMP echo reply. (ICMP is used to transmit control information such as whether the network is smooth and whether the host is reachable between ip hosts and routers)
