Get own domain-name

Virtual machines created by hosters (like Hetzner) usually create individual domain names for each VM.

IP-Address

First step is to get the own global IP-Address:

ip addr

or to directly filter out the IP-Address:

ip addr show eth0 | grep inet | awk '{print $2}' | cut -d / -f 1

next step is to retrieve the PTR entry for the IP-Address:

dig -x *ip-addr* @8.8.8.8 +short

last step is to verify if the Type A Record is also set properly:

dig -t A *ptr-name* @8.8.8.8 +short

In case the Type A Record resolves to the IP-Address of the virtual machine, it can be used as domain-name in the Browser.
