Final answer:
To verify the IP address associated with 'diontraining' on a Linux server, a technician can use the commands ping, nslookup, dig, or host, which provide various details and output styles for domain name and IP address mappings.
Step-by-step explanation:
The correct answer is that a technician can use several commands on a Linux server to verify the IP address associated with a hostname such as 'diontraining'. One common command is ping, which can be used to send packets to the host and see the IP address in the output. However, ping may not work if ICMP packets are blocked by the host’s firewall.
Another command that can be used is nslookup, which queries the domain name system to obtain domain name or IP address mapping. A more modern alternative to nslookup is dig, which provides more detailed information and is considered to have a more user-friendly output. Finally, the host command is another tool that can translate hostnames to IP addresses and vice versa.
To use these commands, you would typically enter them into the terminal followed by the domain name in question. For example, 'ping diontraining.com', 'nslookup diontraining.com', 'dig diontraining.com', or 'host diontraining.com'.
The correct command a technician can use on a Linux server to verify the IP address associated with diontraining is ifconfig diontraining. This command will display network interface information for the specified interface, including the assigned IP address.
Another command that can be used is ip addr show dev diontraining. This command provides similar information but using the newer ip command instead of ifconfig.
Additionally, the command hostname -I can be used to display all IP addresses associated with the server, which includes the IP address associated with diontraining.
