A few days ago, someone asked a very basic question. Where is the opposite version of this script:
http://enterpriseadmins.org/blog/scripting/do-you-have-any-way-of-getting-server-name-from-the-attached-list-of-ips/? They had a list of host names and wanted the associated IP addresses. Since it is somewhat common for a name to resolve to multiple IP addresses, this function has a few more lines as it will loop through each result.
Function Get-HostIP ([string]$hostName) {
try {
[system.net.dns]::GetHostByName($hostName).AddressList | %{
New-Object psobject -Property @{
HostName = $hostName
IPAddress = $_.IPAddressToString
} # End result object
} # end foreach loop
} catch {
New-Object psobject -Property @{
HostName = $hostName
IPAddress = "Unknown/Error"
} # end result object
} # end try/catch
} # end function
Here is a sample result running this function against google.com:
Get-HostIP 'google.com' IPAddress HostName --------- -------- 173.194.46.67 google.com 173.194.46.71 google.com 173.194.46.65 google.com 173.194.46.66 google.com 173.194.46.69 google.com 173.194.46.72 google.com 173.194.46.70 google.com 173.194.46.78 google.com 173.194.46.68 google.com 173.194.46.73 google.com 173.194.46.64 google.com
