Thank you for this excellent explanation, it was what I was assuming but someone asked me a question today during a presentation and it made me wonder.
Sounds like the 2 CDKs on 2 laptops, same corporate network will not be a problem. The questioner was also wondering…what if I want a CDK on a laptop to be shared with my co-workers, where they could hit my URLs and see the apps I have running? Obviously, I have not thought about networking in many years :-) On February 24, 2016 at 7:19:40 PM, Rob Terzi ([email protected]) wrote: A downside of the fixed IP choice in the Vagrantfile is you can't have two boxes running simultaneously on the same machine. A few more details to what Scott said. The hypervisor (VirtualBox, etc.) on the host is doing NAT (network address translation) to create a private network on the host system. If you create a VM yourself under VirtualBox, that's the same as the NAT choice. The private network can't be reached from other systems, they won't know how to route to it, and the host system won't accept packets with that address because it doesn't have any physical adapters on that network. Note: You could run into problems if the (physical) network that the host system is on is using the same subnet (don't remember what the netmask is), so 10.1.2.x. This should be documented some place for troubleshooting. Note: Non-routable doesn't mean it can't be used and routed to as an internal network. It just means Internet routers/gateways shouldn't be routing any of the private reserved networks like 10.x.x.x, 192.168.x.x, 172.16-172.31. --Rob On 2/24/2016 6:33 PM, Scott McCarty wrote: > The 10.x.x.x is a private, non-routable ip, so you can have as many laptops > with a CDK on it, as you want.
