Quick PowerShell Tip!
To list all of the IP addresses on your local system, along with the associated interface name:
Get-NetIPAddress | ft IPAddress, InterfaceAlias
This will include all IPv4 and IPv6 addresses.
On Windows based PCs and Servers, and where IPv6 is enabled on one of the network adapters, you may find that when you do a:
ping name-of-host
… you get an IPv6 address returned in the results. But what if you want to test IPv4 connectivity? You can add a -4 switch to the ping command to force it to use IPv4 as follows:
ping -4 name-of-host
Ping will now ping the IPv4 address as opposed to the IPv6.
It’s worth noting, that if you do want to test for IPv6 connectivity, you can add a -6 switch to force that:
ping -6 name-of-host

What’s a /28? How many IPs do I get to use with a /26? Well, see the table below!
Usable IPs is the Total IPs minus the Network and Broadcast IPs.
