Ubuntu VM with no IP v4 connection, only IP v6
I have a fresh ubuntu 16.04 LTS VM installed on my cloud provider. I cannot get IP V4 connectivity but only IP V6. I can connect to my VM through secure shell and I can also reach it through its domain name (I have installed an apache http server and I can see the test page). However, I wonder why I don't have normal access to the internet. For example, when I run sudo apt-get update some package repositories seem to be reachable while others don't. I have also tried to ping various web sites with no success.
What is going on? What should I do to allow my VM to have normal network access?

Does your provider actually provide IPv4 addresses at all? What's in your system logs?

My cloud provider gives 3 IPv4 addresses for 20 VMs. For this VM, I cannot use an IPv4 address as I need them for other VMs. Which log do you refer to exactly?

I would first check/var/log/syslog. That's where common system activity gets logged. But if your VM hasn't got IPv4 connectivity at all, then there is no point. You can only access IPv6 sites.
