I am trying to access some URLs for work, through a corporate VPN
Connecting to the VPN is fine and some sites resolve just okay.
But for some URLs I cant connect, or ping the address.
If I ask a colleague to nslookup and send me the IP address, I still cant ping the address.
However if I add the IP and base URL to my /etc/hosts it works just fine.
I have checked its not blocked by selinux or my firewall or iptables.
Im trying to understand whats happening, the IP is likely to change so I would like to not have to rely upon the static IP in the /etc/hosts

I have a VPN setup with a client that cannot ping our internal subnet when the VPN is up. The client has pings disabled on their side.
