Error in ipv4 only host.

[whygit2000]

My network env only have IPv4, and the script can get correct ipv4 and show, but can't update.
when running the script with the yaml config file in Alma Linux 9, even I had set ipv6 to “false” in yaml file, but still got error messege below:

ERROR: [get_ip] Failed to get ipv6

and stuck at this point, can't update the ip v4.
