probably because its a CNAME, and points to a different domain, and
nslookup isn't following that.
$ nslookup -query=any www.bipa.at
Server: xxx.xxx.xxx.xxx
Address: xxx.xxx.xxx.xxx#53
Non-authoritative answer:
www.bipa.at canonical name = www.bipa.at.cdn.cloudflare.net.
Authoritative answers can be found from:
bipa.at nameserver = dns2.telekom.at.
bipa.at nameserver = dns3.telekom.at.
bipa.at nameserver = dns1.telekom.at.
dns1.telekom.at internet address = 80.120.17.26
dns2.telekom.at internet address = 213.33.99.79
dns3.telekom.at internet address = 80.240.225.50
that said, I've gotten to using 'host' rather than 'nslookup'. host is
part of the bind-utils package for obtuse reasons.
$ host www.bipa.at
www.bipa.at is an alias for www.bipa.at.cdn.cloudflare.net.
www.bipa.at.cdn.cloudflare.net has address 104.16.168.136
www.bipa.at.cdn.cloudflare.net has address 104.16.169.136
