To verify TCP IPv6 protocols, you can ping the loopback address, which is ::1
. This address is used to test the local network stack of the device itself. Additionally, you can ping a well-known IPv6 address, such as 2001:4860:4860::8888
, which is a Google Public DNS server, to check connectivity over IPv6.
1::1
IP is properly installed on the host.

To find a specific type of address in IPv6, you can refer to the address structure and prefix. IPv6 addresses are categorized into various types, such as global unicast, link-local, multicast, and anycast, each with distinct prefixes. For example, link-local addresses start with "FE80::/10," while multicast addresses start with "FF00::/8." You can use network tools or commands like ping, traceroute, or specific IPv6 address lookup tools to identify and verify the type of address in use.
TCP/IP can be verified as installed and operating by using the 'ping' command against the localhost address: ping 127.0.0.1 or ping localhost

ping uses the ICMP protocol.
Ping the default gateway IP address to know if it is reachable
PING
Assuming IPv4 ICMP. Ping uses IP for transport. Ping in itself is an "Echo Request", which is a function of the ICMP protocol. The IP Packet will carry the ICMP protocol from end-to-end. ICMP has a protocol number of 1, so the "Protocol" field in the IPv4 header will contain "1" as a reference to the ICMP payload. For IPv6, ICMPv6 is used, and the transport will be IPv6.
