Here is a simple one-liner that returns your computers’ current IP address and its full DNS name:
PS> [System.Net.Dns]::GetHostEntry('')
HostName Aliases AddressList
-------- ------- -----------
DESKTOP-7AAMJLF {} {fe80::532:c4e:c409:b987%18, 192.168.2.129}
To examine a remote machine, simply submit the computer remote name instead of an empty string:
PS> [System.Net.Dns]::GetHostEntry('microsoft.com')
HostName Aliases AddressList
-------- ------- -----------
microsoft.com {} {40.113.200.201, 40.76.4.15, 104.215.148.63, 13.77.161.179...}
If you just would like to get the list of assigned IP addresses, try this:
PS> [System.Net.Dns]::GetHostEntry('microsoft.com').AddressList.IPAddressToString
40.113.200.201
40.76.4.15
104.215.148.63
13.77.161.179
40.112.72.205
Your learning points:
- The System.Net.DNS class contains a number of useful DNS-related methods. GetHostEntry() is especially useful because it accepts both computer names and IP addresses and returns the corresponding DNS names and IP addresses.
- Submit an empty string to view your machines’ own settings
