Why doesn't the URL with the site's subdomain open if the main domain is available, while the ip of the domain and subdomain are different, is this normal?

Question

Ping

the main domain (timeweb.net) is pinged and opened, but redirected to .com. (they have the same ip), I try to open confluence.timeweb.net - it does not open and does not ping (there is no answer). at the same time, the ping shows some strange (internal?) ip

ping confluence.timeweb.net
PING confluence.timeweb.net (192.168.0.242) 56(84) bytes of data.
--- confluence.timeweb.net ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7166ms

.com also fails to ping

ping confluence.timeweb.com
PING confluence.timeweb.com (212.109.215.175) 56(84) bytes of data.
--- confluence.timeweb.com ping statistics ---
11 packets transmitted, 0 received, 100% packet loss, time 10216ms

Answer 1

because this is how the administrator of the timeweb.net domain configured the DNS records
