Get Public IP address of Azure VM from shell on VM - part II

Last year I wrote a quick note with a method of getting Azure VM public address from the shell on VM. Recently I spent a bit more time to look at https://docs.microsoft.com/en-us/azure/virtual-machines/linux/instance-metadata-service and found more precise call to get IP address from the metadata url: 

curl -H Metadata:true \
 "http://169.254.169.254/metadata/instance/network/interface/0/ipv4/ipAddress/0/publicIpAddress?api-version=2017-08-01&format=text"

BTW. The same method allows to get a private IP address.

curl -H Metadata:true \
 "http://169.254.169.254/metadata/instance/network/interface/0/ipv4/ipAddress/0/privateIpAddress?api-version=2017-08-01&format=text"
