pinging two different URLs, response comes from same IP address (server), Is that possible?

I am pinging two different URL sites (ping www.xyz.com and ping
www.abc.com), the reply comes from same server, Is that possible?. In
the ping reply, the IP address is same. How that is possible?.

How can I know the remote web server is running based on Linux?. Or
Windows based?.

Thanks.

You do NOT ping a URL, you ping a hostname (or IP). It is possible that
they are name based virtual hosts (apache and other web servers can do
that). The content is based on the Host header in the HTTP request.

Depending on your browser, it might show http response headers, or you
could use "wget -S -O - http://whatever/" to see what the server
identifies itself as. The 'nmap' program can often identify an OS, but if
there are no signatures it can identify, it might just pick up the Linux
signatures from your end, or it may be misguided by a router in the path.
You have to be cautious about port scanning any box you do not control
anyway, because they may misread it is a crack attempt.

In Apache you can use virtual hosts.

Looking a google.com
host google.com
google.com has address 216.239.39.99
google.com has address 216.239.37.99
google.com has address 216.239.57.99

so a ping google.com could return any one of the three.

For multiple machines behind the same router, the router could be set up
to respond to all pings.
