NAT Network, the VMs can communicate but your host cannot access them by default. NAT VMs have internet but cannot communicate with each other. Bridged is simple and allows full LAN access as if you had a physical machine plugged in but is often bad for testing, work or corporate environments and is not very portable when it comes to moving your VMs to other locations and networks. Here is how you can use NAT Ne........

A lot of people think arp wil do it but the arp table will only show devices you have communicated with. Using nmap is a quick and simple way to scan a range to find a machine you may not know the IP for: eg: nmap -sP 10.1.5.0/24 Just change the above to your subnet........

VMWare bridged adapter not working: Message from system: The network bridge on device vmnet0 is not running. The virtual machine will not be able to communicate with the host or with other machines on your network. Failed to connect virtual device Ethernet1. I'm not sure how to fix this but one of the issues is that my eth0 became eth1 after moving my hard drives to a new motherboard.
